Peek inside the human genome and, among the 20,000 or so genes that serve as building blocks of life, you’ll find flecks of DNA left behind by viruses that infected our primate ancestors tens of millions of years ago.

Scientists have long considered these ancient hitchhikers, known as endogenous retroviruses, as inert or "junk" DNA that were rendered harmless millennia ago. But new ŷ��ڱ��Ƶ research shows that, when reawakened, they can play a critical role in helping cancer survive and thrive. The study also suggests that silencing certain endogenous retroviruses can make cancer treatments work better.

“Our study shows that diseases today can be significantly influenced by these ancient viral infections that, until recently, very few researchers were paying attention to,” said Edward Chuong, an assistant professor of molecular, cellular and developmental biology at ŷ��ڱ��Ƶ Boulder’s BioFrontiers Institute.

After slipping into the cells of our primate ancestors, these invaders coaxed their unknowing hosts into copying and carrying their genetic material — passing their DNA on to future generations.

While endogenous retroviruses can no longer sicken their hosts or spread like live viruses, they can act as switches that turn on nearby genes, with both good and bad results.

On the plus side, they contributed to the development of the placenta, a critical milestone in human evolution. Chuong’s research also shows they can switch on genes that help us fight infection.

However, endogenous retroviruses also have a dark side.

Chuong’s latest study found that a lineage known as LTR10 is remarkably active in about a third of colon cancer tumors, where it appears to fire up genes that inflame cancer.

The good news: When those viral relics are silenced, the cancer-promoting genes go dark too, and tumor-shrinking treatments become more effective.

As a leading researcher in the burgeoning field, Chuong hopes that by better understanding these oft-neglected bits of the genome, scientists can come up with new ways to treat modern-day illnesses.

Cannabis and Pregnancy

Marijuana use during pregnancy has been linked to childhood sleep problems for up to a decade, according to a ŷ��ڱ��Ƶ Boulder study, which is the first to suggest marijuana use can impact children’s sleep long term. As legalization spreads, roughly 7% of pregnant women in the U.S. are using marijuana to help curb morning sickness. Lead author John Hewitt, director of ŷ��ڱ��Ƶ’s Institute for Behavioral Genetics, said, “This study is one more example of why pregnant women are advised to avoid substance use, including cannabis.”

Teensy, Fast and Strong

Inspired by cockroaches, mechanical engineering assistant professor Kaushik Jayaram created one of the world’s smallest, fastest robots, HAMR-Jr. Weighing less than a paperclip, the four-legged robot is roughly the size of a penny. It is able to carry 10 times its body weight and moves about one foot per second. According to Jayaram, there are a lot of potential applications with HAMR-Jr., such as airplane engine inspections or human surgeries. "I want to build robots that can get out of the lab and run around like bugs,” Jayaram said.

New Center to Advance Quantum Science and Engineering

With a $25 million National Science Foundation award, ŷ��ڱ��Ƶ Boulder is launching a new quantum science and engineering research center, led by physicist and JILA fellow Jun Ye. The center will partner with 11 other research organizations in the U.S. and abroad — including Harvard, Stanford and MIT — to create new technologies using advancements in areas related to quantum entanglement, quantum sensing and more.
“We’re asking how we can take advantage of recent advances in quantum physics to actually solve useful problems for society,” said Ye.

Everything...connects back to wanting to make sure that Black women in particular — [and] Black people in general — get to pursue [their] dreams in the daytime, not just when everyone else is asleep.”

The beeping was constant.

In the chaos of rushing between Iŷ��ڱ��Ƶ patients and making critical decisions on the spot, calls flooded Marco Uribe’s (Soc’12) pager.

People desperate for an update on their mother, father, spouse. Needing to know — unable to see or speak to them — their conditions.

Marco had to explain on the phone to families that their loved one was dying from the COVID-19 virus, sometimes being forced to ask if their ventilator could go to someone else with a higher probability of surviving.

“Many nights I stay up thinking about those conversations with families.”

One shift, he became overwhelmed. He slipped into an empty room in the Jacobi Medical Center in the Bronx, New York, to call the person he needed to speak to most — his wife, Whitney Lewis Uribe (Jour’12).

“I remember him calling me completely shaken, asking, ‘How do I even ask a family to answer this question?’” Whitney said.

Marco added, “Many nights I stay up thinking about those conversations with families.”

It was March 2020 and Marco was three months away from completing his first year of residency through the ŷ��ڱ��Ƶ School of Medicine’s advanced anesthesiology program. The residency includes three years of specialized training after completing an intern year. ŷ��ڱ��Ƶ assigned Marco to a hospital system in the Bronx for his intern year, which began in June 2019.

“New York was definitely a surprise for us,” said Whitney.

But as the pandemic ripped through the city, the couple realized they were exactly where they were supposed to be. New York was an experience to learn, grow and lean on each other — just as they had for the past 12 years.

Hallett Hall

Marco and Whitney Uribe met in August 2008 during freshman move-in day at ŷ��ڱ��Ƶ Boulder.

Marco and Whitney met in August 2008 during freshman move-in day at ŷ��ڱ��Ƶ Boulder. Marco was coming from Austin, Texas, to start a pre-med track, and Whitney from Steamboat Springs, ŷ��ڱ��Ƶ, to study journalism. They were on the same floor in Hallett Hall.

“We both caught each other’s eye,” said Whitney.

When Marco’s mom and sister, Marisa, came to visit for Homecoming, he solicited Marisa to invite Whitney to join them at a family tailgate — and 13-year-old Marisa was very insistent.

“The litmus was how Whitney interacted with my little sister, who had special needs,” Marco said. “When I saw that she treated Marisa with love and respect, I knew she had a big heart.”

As their relationship developed, Whitney learned how special Marisa was and how much she meant to Marco. Doctors diagnosed her with brain cancer as an infant, and the chemotherapy and radiation she underwent until age 5 stunted her neurological development and altered her hormonal balance.

“She had an extra big capacity to love everyone around her,” said Whitney.

“She was my reason to go into medicine,” Marco said.

Med School

After graduating from ŷ��ڱ��Ƶ in 2012, Marco applied to medical schools while he skied, fly-fished and waited tables in ŷ��ڱ��Ƶ. Whitney moved to Los Angeles to work for an entertainment production company. They dated long-distance.

In 2013, Marco was accepted to medical school at the University of Texas Health Science Center San Antonio. After a year and a half, Whitney joined him in Texas to work in the nonprofit sector. They were engaged near the Flatirons during a trip to Boulder in 2015, which is where they had their first date.

In Marco’s second year of medical school, Marisa was diagnosed with colon cancer. The couple put their lives on hold to spend time with her. She died in September 2016 at 21 years old.

“We leaned on each other a lot during that time,” said Whitney. “We grew closer.”

Focusing on his studies was “a serious challenge” during that period, Marco said, but after some time off and Whitney’s support, he continued with medical school.

Marco and Whitney married in July 2017 in Steamboat Springs. Two years later, Marco graduated and pursued residency options. ŷ��ڱ��Ƶ’s advanced anesthesiology program at the Anschutz campus was his top choice.

“Anesthesia really came to me,” said Marco. “When Marisa was really sick, an anesthesiologist gave her an epidural catheter which greatly helped in managing her pain so we could spend quality time together. It gave me some of the most cherished time with my sister.”

After Marco was accepted into ŷ��ڱ��Ƶ and subsequently assigned to New York, the couple — both 29 years old at the time — rented a 500-square-foot apartment in Manhattan and moved in with their 65-pound wirehaired griffon, Rooster.

Whitney volunteered for a childhood cancer research organization and trained to get her certification in Pilates. Marco worked in the general surgery department at a hospital system in the Bronx, where many units were understaffed and overwhelmed before the pandemic.

“It was sink-or-swim kind of training,” Marco said.

“I’d go to the emergency department and ask colleagues, ‘What do you think of this COVID thing? Are we prepared?’”

The COVID Tidal Wave

Marco first heard of COVID-19 in December.

“It was something we knew was out there but hadn’t been completely studied. There didn’t seem to be anything concrete,” he said. “In January it became more of a discussion.”

In February things seemed different.

“I’d go to the emergency department and ask colleagues, ‘What do you think of this COVID thing? Are we prepared?’” Marco recalled. “They said it’s coming and it’s going to hit us like a tidal wave.”

Marco prepared to dive in.

“I remember the day when he came home and he said this is going to be really hard and a lot of people are going to die,” Whitney said. “I stopped watching the news. I needed to match his fearless energy because he was now going to be seeing this firsthand.”

Marco volunteered to work in his hospital’s Iŷ��ڱ��Ƶ doing critical care for COVID-19 patients. He started work at 5:30 a.m. and sometimes wouldn’t return home until 9 p.m. or later. Whitney remembers giving him protein shakes often as he was too exhausted to eat.

“Eight hours of sleep minus the commute time wasn’t a lot, but it was worth going home,” Marco said. “I would change out of scrubs in the hallway, take my shoes off, put those scrubs in a bag, go straight to the laundry and take a shower.”

In mid-April, Marco, top, second from left, was featured on CBS News wheeling a recovered COVID-19 patient out of a New York City hospital.

By the end of March, the entire hospital and every Iŷ��ڱ��Ƶ floor was overflowing, and ventilators were running sparse. While attending physicians frantically tried to obtain supplies, staff and space for dying patients, the residents helped run the Iŷ��ڱ��Ƶs.

“I quickly learned how to serve my patients as a critical care physician,” Marco said.

Whitney helped him create talking points for difficult conversations with families.

Despite it all, Marco knew he was where he was supposed to be.

“This is why we go into medicine,” he said. “This is our call.”

In mid-April, Marco — wearing a ŷ��ڱ��Ƶ Boulder lanyard — was featured on CBS News wheeling a recovered patient out of the hospital to his family.

“I would have wanted to be in the fight whether or not I was in New York,” Marco said. “The fact that I was there by luck — I thank God for the experience.”

Return to ŷ��ڱ��Ƶ

At the end of June, the couple moved from New York to a historic house in the Berkeley neighborhood of Denver.

“Every time we move to a new city it feels like a new chapter,” Whitney said. “We trust what is in store for us, good or bad.”

Whitney sought out an advertising position and is continuing her volunteer work in childhood cancer research. In July, Marco began the second year of his residency at ŷ��ڱ��Ƶ's medical campus, focused once again on anesthesiology.

But, he added, “We’re excited for whatever could come next.”

Twins Cara (MCDBio'11) and Amy Faliano (MCDBio'11) have been on the frontlines of the COVID-19 pandemic in the labs of the UC Health system: Cara is the coordinator of laboratory safety for UCHealth in the Denver Metro area, and Amy is a lead medical laboratory scientist at UCHealth's Highlands Ranch community hospital. Here, the sisters discuss their love for biology, what it’s like working in separate labs and the benefits of having each other.

What drew you to biology and medical testing?

Cara: Amy and I have loved science since we were little girls. Our mom used to take us to the library and we'd check out stacks of books at a time. We stayed study buddies throughout our schooling and found that biology, specifically things on the microscopic level, sparked our interest the most, so studying MCDB at ŷ��ڱ��Ƶ was an easy choice for both of us.

What was your favorite thing at ŷ��ڱ��Ƶ Boulder?

Cara: Having a Division 1 football team to support was a dream for both of us. We never missed a football game and attended a lot of basketball as well — and still love to go watch ŷ��ڱ��Ƶ play.

Amy: I loved the extracurriculars, like sports games, giving campus tours and being in ŷ��ڱ��Ƶ Collegiate Chorale.

Amy Faliano

When did you first become concerned about COVID-19?

Cara: I help manage the special pathogens unit in my hospital, so I'm always reading about infectious disease news. I would say around Christmas is when COVID-19 really started to catch my attention, because it's well-known that a SARS-like or flu-like respiratory illness would be the next "pandemic" and this seemed mysterious enough to fit the bill.

What COVID-related questions have you been getting most from friends and family?

Cara: We're getting a lot of questions about how the testing works, which is great! Lab testing and medical laboratory science has always been one of the less-talked-about fields in the medical world, so it's been great to have a spotlight shined overall on the great work that clinical labs do to support patient care.

Amy: A lot of friends and family who have reached out had questions about how the testing is performed, what the results look like. One of my aunts just had to know if the novel coronavirus really looks like the "spiky ball' picture she has seen on the news. The answer is yes, that is what it looks like under an electron microscope.

Cara Faliano

What has it been like working through this difficult time?

Cara: Like anyone in healthcare would say, this has been a very tiring and trying couple of months of hard work, rapid changes and adapting to the situation as it develops. I've personally been involved on the more administrative side of the laboratory, so I've re-written the lab's "COVID-19" procedure more times than I can count, have been tasked with things like helping to create drive-thru testing locations, have had to find creative new inventory for the lab to use in supply chain shortages — like 3D-printed swabs — and have been managing the inventory of testing supplies for the entire hospital system. Everyone is wearing many hats in this pandemic, and it's been a scramble for all in the lab.

Amy: I am a leader in the laboratory at UCHealth Highlands Ranch Hospital, a community hospital in the UCHealth system. I had to quickly validate new testing for COVID-19, train all staff and figure out how to balance that testing with all of our normal testing for patients seen at our hospital and clinic. It was stressful to have to get the validation paperwork and new procedures at a rapid pace, and I have worked a lot of long hours.

You both worked in blood banks during the 2012 Aurora movie theater shooting. What was that like?

Amy: We both got called into work the night of the shootings and came to the hospital blood bank right away. That was a crazy night of assisting in testing and preparing blood products for a mass-casualty situation, but definitely affirmed my decision to go into the career field. What the hospital laboratory does is so important, and this pandemic is another reminder of that.

How has having each other been therapeutic?

Cara: My work on the admin side directly impacts Amy in her lab, as her lab follows the procedures I've written and uses the same materials, so we've been able to brainstorm together on some things or bounce questions off of each other.

Amy: Through the stress of the pandemic it was nice to have someone who was there for me, and understood how hard it was to have to continue working as if things were business as usual. Cara understood how physically and mentally exhausting it was to have to work hard and work long hours. I needed her to vent to, but also to inspire me to go work hard again the next day since we were in this together.

Both of you went to the same university, same degree, same career field — just how competitive are you two?

Cara: Neither of us have a competitive bone in our bodies! We've always been really supportive of each other and want the other to do well.

Amy: I agree with that! It makes sense that we ended up in similar careers since our love of science has always been the thing that bonded us. I think we used our different strengths to find our niches in the career field, no competitiveness there.

What's one common misconception about being a twin?

Cara: I think people sometimes love to assume that we do everything together since we're in the same career field. We've rarely worked directly together, and have our own lives and interests outside of work. We're just like any other really close friends!

Amy: I don't think twins are that different from any other siblings who are close.

ŷ��ڱ��Ƶ Boulder computer science assistant professor Mirela Alistar wants to make healthcare more personal. Her work with microfluidic biochips is getting us there. Here, the director of the ATLAS Institute’s Living Matter Lab discusses her biochips, in-home testing and melding science with art.

What brought you to ŷ��ڱ��Ƶ?

I was ready to start my own research group, so I embarked on an exciting journey of applying to more than 100 universities for a faculty position. While interviewing all over the world, I was impressed with the interdisciplinarity of ATLAS Institute, with ŷ��ڱ��Ƶ’s ambition and drive to support young faculty and with Boulder’s natural beauty and progressive culture. Needless to say, choosing ŷ��ڱ��Ƶ Boulder was the easiest decision I ever made.

What is your main intention with the Living Matter Lab?

As the name says, I am interested in living matter, especially in its non-human form. In the Living Matter Lab, we explore the connection between humans and the life around us by focusing on personal healthcare. Specifically, we are investigating how far we can push healthcare into the hands of people by the means of technology. To do this, we develop biochip instruments that can be used at home by people for various medical applications.

Can you describe these instruments?

Biochips are small electronic devices that manipulate droplets of fluids by executing bio-protocols — programs that move, split and mix droplets containing chemical compounds (reagents). Biochips automate processes traditionally performed in wet labs. The key advantage of biochips is that they are adaptable, thus capable of running different bio-protocols. Instead of going to a specialist, a patient can download a bio-protocol.

Why do we need biochips?

Microfluidics is the engineering that figures out how to manipulate fluids in very small amounts, at micro level. You see, fluids at large scale — the coffee in your cup, the water coming from the tap — behave very differently than when in very small amounts. To give you an idea of how small we are talking, the size of a rain droplet is about 20 microliters [one-millionth of a liter] and that is around the maximum size approached with microfluidics. Such tiny amounts of fluids are hard to manipulate because they have a strong surface tension that has to be overcome. Biochip instruments are able to manipulate such droplets in the picoliter [a trillionth of a liter] range.

What sort of tests might people perform with these?

Biochips have been shown to be able to perform basic tests, such as detecting the glucose levels on physiological fluids such as blood, saliva, urine and serum. We are working on developing a procedure that allows biochips to test for bacterial and viral infections.

Mirela Alistar

Could these biochips detect coronaviruses or other viral infections?

I am working on developing biochips that can perform ELISA [enzyme-linked immunosorbent assay], a standard procedure used to detect viral infections. ELISA is currently used as one of the methods of testing for [the novel] coronavirus. We do hope during the next year we will have a biochip that can run ELISA, and that means it will be able to detect various viral infections. I am also aware and even had collaborated with other research labs working on the same problem. However, even if any of us are successful in developing such biochips, they will still need quite a few years of development until approved to be used as a diagnosis tool.

What do you see them being used for the most initially?

I foresee a progressive roadmap for biochips, where they first will be adopted by doctors as an effective way of performing quick tests, an essential step in differential diagnosis. Then, I see a lot of potential for biochips to be used in mobile settings, such as during traveling or outdoor activities. Finally, biochips will empower patients to perform selected tests at home, as part of their decision whether to see a doctor.

How could these change our healthcare system?

Similar to how mobile computing has enabled over 60% of the population to solve a wide range of problems by means of software, I believe that biochips will change how people interact with a wide range of healthcare processes. In the long run, I believe biochips will lead to democratizing healthcare, and to a process that moves away from the current ‘one size fits all’ concept towards more personalized care.

Are there non-health uses for these biochips?

Yes, for example, researchers at University of Washington forked one of our older biochip devices and are using it for DNA computing. That means they embed DNA inside the droplets and use the droplet mixing and splitting to perform operations on the information contained in the DNA. I am also aware of people that replicated our biochips to use them for perfume mixing. One of the students in my class is designing a biochip that tells the time, basically a clock with fluids.

What other things are you working on right now?

Apart from personal healthcare, we have a second angle to approach our work in the Living Matter Lab. This angle is an artistic one, where we explore and design interactions and tangible interfaces between humans and non-human life. Examples of current projects include designing an escape room where humans and dinoflagellates [algae] collaborate to find the exit, developing do-it-yourself spirulina bioreactors for at-home use and inventing biomaterials that allow kids to grow their own toys and people to ‘cook’ their own clothes.

What do you do outside of your work?

I am focused right now on building a strong community in Boulder that engages in sci-art and bio-art. I would love to see science, technology and art coming together in interactive installations and performances available to the public at large.

John Warner has climbed and skied mountains in the United States and abroad, raced motorcycles and mountain bikes and, by the way, also served as a mayor, search-and-rescue volunteer, orchestra backer and dentist-of-mercy in Guatemala.

If life is what you make of it, Warner (Bio’73) knows the drill.

As a ŷ��ڱ��Ƶ Boulder student, Warner liked the natural sciences and initially planned to pursue medical school. But as an undergrad, he happened to work with a group of ŷ��ڱ��Ƶ dentists who were pioneering a protocol to stimulate dental-bone growth using bone marrow that Warner harvested from cadavers. He went on to dental school instead, at ŷ��ڱ��Ƶ’s School of Dental Medicine, and later opened a practice in Breckenridge.

When Warner and his wife, Carre, moved there, Breckenridge was a lot smaller and his practice didn’t keep him too busy. Civic engagement filled the gap. He led the Breckenridge Music Institute and volunteered for the Summit County Search and Rescue Group. He also founded the Summit Huts Association, a nonprofit that rents backcountry cabins, and served multiple terms on the town council and as mayor.

After Hurricane Katrina in 2005, he provided free dental care in New Orleans’ Ninth Ward. Later, he volunteered similar services in Guatemala.

The Guatemalans Warner treated lived far from dental clinics. Many had never seen a dentist. His patients sat on bags of grain while he mostly pulled teeth and filled cavities. He did this without basic diagnostic tools, such as an X-ray machine.

Like many Coloradans, Warner, who spent much of his childhood in Denver, answers to yet another calling: The outdoors.

He and some buddies have skied hut to hut in Austria, France, Switzerland, Italy and Canada. They’ve trained at Mount Rainier and climbed Denali and Aconcagua — North and South America’s highest peaks, respectively.

Living at 9,600 feet gives Warner an edge at altitude, he said.

Recently, he completed the Double Triple Bypass, a cycling event in which he rode 220 miles and climbed 22,000 feet in two days.

He’s also a seven-time finisher of the Elk Mountain Grand Traverse, a midnight ski race from Crested Butte to Aspen. In 2015, he and teammate Jack Wolfe became the oldest team — combined age: 123 — to complete the race.

In his mid-60s, he skied the Cristo Couloir, which tumbles down the southern flanks of Quandary Peak, a fourteener. He also skied down Torreys Peak, descending a route no more than 50 yards wide in spots, with rocks lining both sides.

That might sound like a daredevil stunt; Warner insists he’s careful.

“I don’t want to make a mistake,” he said, adding that he doesn’t want his former search-and-rescue colleagues to have to collect his body.

When not pushing limits on skis, peaks or bikes, Warner channels his energy into community service. It’s “helped me professionally,” he said, “and helped me be a better person.”

Course Correction

Courtnie Paschall (Neuro, ElEngr’15)

For Courtnie Paschall (Neuro, ElEngr’15), working on a drug trial for patients with schizophrenia while applying to 20 MD-PhD programs counts as light duty.

By the time she touched down at ŷ��ڱ��Ƶ-Boulder in 2013 to study neuroscience and electrical engineering, she had proved she could handle stress: She’d graduated from the U.S. Naval Academy (’08), where she studied physics and Mandarin Chinese, attained the rank of Navy lieutenant and trained for years in a T-34C “Turbomentor” airplane and a modified Bell 206 helicopter.

She’d not only learned to fly both fixed-wing aircraft and rotorcraft, but to perform stunts also — figure-eights, Immelmann turns and barrel rolls.

Then she charted a new course: Today Paschall is a research assistant at the University of ŷ��ڱ��Ƶ Anschutz Medical Campus and headed for a career in medicine and neuroscience research.

“The next decade in neuroscience is going to revolutionize the way we approach our health,” she says.

Paschall — who in May graduated from ŷ��ڱ��Ƶ summa cum laude and was named Outstanding Graduate for the College of Arts and Sciences — had long thought the military would be her life: Her parents are both Marines. Her dad is still on active duty.

She was two weeks from “winging” — a graduation ceremony in which military pilots celebrate the end of flight school and sign an eight-year service contract —when the Navy decided to pare its forces.

Paschall had the option to sign up or move on.

Given her deep military ties, it was a “terrifying” crossroads, she says — and like most crossroads, also an opportunity.

“The blood rushed from my face,” she says. “I had to walk outside and take a deep breath and just make sure that I was really willing to commit to an unknown future and give up everything this path meant.”

Paschall was 23.

“The military was all I’d ever known,” she says, “and I wanted to do something else.”

That something else was neuroscience, which led her to ŷ��ڱ��Ƶ-Boulder. She enrolled as a junior with an unusually refined sense of purpose.

In her honors thesis, Paschall probed the morphological effects of marijuana on three subcortical brain structures shown to be affected by drug use in human adults.

Marie Banich, professor of psychology and neuroscience and Paschall’s thesis advisor, described her as “exceptionally bright and motivated” — and also fast, finishing her honors thesis in nine months, half the time of an average honors student.

Now the pilot has filed an MD-PhD flight plan.

Says Paschall, “I am deeply fascinated by human cognition — how we think, what causes cognitive dysfunction, and how can we intervene to restore normal processes.”

Resuscitating a Dormant Dream: Toshiko Luckow

Resuscitating a Dormant Dream: Toshiko Luckow Anonymous (not verified) Fri, 03/01/2013 - 00:00

Toshiko Luckow’s (MTeleComm’87, MD’10) motto for life came from a professor.

“You can do everything you want to do — you just can’t do it all at once,” she recalls him saying. “So, voilà! That has been my motto.”

When she graduated in 2010, Toshiko was one of the oldest students to earn a medical degree in the history of the University of ŷ��ڱ��Ƶ. At 53, an age when most professionals are beginning their last decade in the workforce, she began her family medicine residency at the Medical College of Wisconsin, St. Joseph Hospital in Milwaukee.

Toshiko, who was raised in Japan, came to the United States at age 15 as a foreign exchange student. Her English vocabulary consisted of the words “yes,” “no” and “thank you.”

After college Toshiko pursued a career in education, attending ŷ��ڱ��Ƶ-Boulder for a teaching certificate in English as a Second Language. She also earned a master’s degree in telecommunications.

When she and her husband, who also is fluent in Japanese, moved to Tokyo, she landed a job downtown at AT&T working as a systems engineer. The couple moved back to the U.S. just as the telecom industry was contracting and launched a successful Japanese technical translation business in Boulder.

“I can confidently say that I have always taken actions that are true to my dreams, and they have led me to challenging and successful careers, volunteer activities and my family,” she says. “At the same time, though, I have always had a feeling that something was not quite complete.”

When she turned 40, she finally acknowledged her deeply rooted desire to become a medical doctor. Both her father and grandfather were doctors, but the cultural norms in Japan when she was a child didn’t encourage girls to become doctors. The dream lay dormant for decades.

Although she will have significant debt from medical school, that doesn’t deter her.

“I will have to work for a long time, or I’ll have to drop dead and have the loan forgiven,” she says.

Odds are, she’s got a long career ahead of her. Toshiko’s father, an internist with a doctorate, just retired last year at age 84.

Toshiko’s commitment to her dreams already has inspired others. Last year, her 54-year-old husband, Mike Luckow (DistSt’84), whom she met at ŷ��ڱ��Ƶ-Boulder, became the oldest student to begin medical school at ŷ��ڱ��Ƶ. When Toshiko finishes her residency in Wisconsin, she hopes to return to ŷ��ڱ��Ƶ.
