At Nationwide Children’s, the Steve and Cindy Rasmussen Institute of Genomic Medicine brings the rapidly advancing science to the clinic to improve diagnosis, therapies and outcomes for children with gene-based conditions.
At the center of this research-to-clinic integration sits physician-scientist Beth Kozel, MD, PhD, chief of the Division of Genetics and Genomic Medicine, director of Constitutional Genomics Translational Research and a principal investigator in the Institute for Genomic Medicine. As a clinical geneticist, Dr. Kozel has dedicated most of her career to advancing genomics and incorporating it into clinical care in the truest sense of translational research — with “one foot in the clinical realm and one foot in research.”
Expanding her research on elastin, which she began with the National Institutes of Health, she aims to answer questions involving elastin-related rare diseases, including Williams Syndrome. Whether she’s mentoring, leading, researching or treating, Dr. Kozel’s mission is to develop therapeutics, apply novel concepts that impact rare disease management and foster the next generation of physician-scientists as they discover new frontiers in genomics.

Read on to learn more about Dr. Kozel’s work and research career.
Why did you decide to pursue a career in genomics?
I pursued a physician-scientist (MD-PhD) program at Washington University School of Medicine. During my scientific training, I worked in a basic science learning the basics of connective tissue biology, including how the molecule elastin is formed and how it affects the body’s function when there isn’t enough of it. Elastin, as its name sounds is the molecule in your body that makes your tissues like your blood vessels, lungs, and skin stretch. In PhD training, experiments have a certain expected cause and effect. When you change the molecule a certain way, it reacts a certain way. When I finished my training and began caring for people with changes in these genes, however, I saw a much broader range of outcomes. People with the same genetic change could present very differently. That raised questions that continue to fascinate me: Where does that variation come from? How can the same genetic change lead to such different outcomes from one person to another? It really made me think.
I’ve always been driven by curiosity when the patient in front of me says, “I have this health problem, and I don’t understand why it is happening.” My response is, “I bet we could figure that out if we study it further.”
That curiosity led me to study genetic variation among people and, ultimately, to better understand which genomic changes contribute to disease and which are simply part of what makes each of us different.
How has your work evolved at Nationwide Children’s?
Since arriving at Nationwide Children’s, we’ve been able to apply research concepts clinically that weren’t possible just a couple of years ago. Coming here has allowed me to collaborate with an incredible group of gene therapy experts at the Center for Gene Therapy and diagnostic experts at the Institute of Genomic Medicine and to focus on that critical space between diagnosis and therapeutics. I knew Nationwide Children’s would be a good match regarding where the research was heading and what we could do for patients around the world.
We had already laid the foundation for research and clinical work to identify Williams Syndrome; we just needed to move into an interventional therapeutic space next. Now, we can see a patient in the intensive care unit, order genomic testing, get results back in two days and use that information to create a personalized plan to guide their care. This was not a process we could perform at this scale two or three years ago. We’re now able to translate research into clinical care at a pace we simply couldn’t before.
What do you hope to accomplish in your research and professional development going forward?
From the research perspective, we’re focused on the therapeutic aspects of elastic fiber disease. How do we take what we know about the fundamental biology of elastin fiber formation to put it to work to improve rare disease and chronic health conditions? We will continue to study the fundamental biology that underlies it, because that helps us optimize a therapeutic system better, but ultimately our goal is treatment for our patients. Regarding my broader clinical role as the chief of Genetics and Genomic Medicine, we have been redefining what genetics does and how we engage in clinical care.
Fun Facts About Dr. Kozel
What’s your favorite word, and why?
Maybe an unusual choice, but “yet” is a word I use a lot. When someone says, “I don’t know how to do that,” or “We don’t know how to solve that,” adding “yet” changes the perspective. It acknowledges where we are while reminding us we can keep working to get somewhere better.
What would be your dream job if you could do anything (that wasn’t working in research)?
I’d love to be a flower farmer. Knowing myself, I’d probably still turn it into an experiment by trying different varieties, changing one thing at a time and tracking what worked. Apparently, I have a hard time imagining a life that doesn’t involve some kind of discovery.
What’s your favorite food?
Cheese — in all its forms from simple to gourmet. It is a comfort food.
Favorite band/genre/artist?
This one changes all the time — I think my favorite genre is classic, sing-out-loud songs that make for a good soundtrack to a family road trip.
Favorite way to relax?
I’m not sure I’m good at relaxing, but my favorite time spent is in dinnertime conversations with my family. We have different topics every day, ranging from world events to perspectives on a new idea or trend. I so enjoy having the opportunity to learn about the people my children are becoming.
Improving technologies have allowed us into spaces where our sickest people in the hospital get timely answers to make meaningful decisions. The next phase, in parallel to the research we’re doing, is being able to say, now that we know the genetic answer, what do we do about it?
Understanding a health problem at a genetic level helps determine where to go next in a patient’s treatment. Eventually, we will use the research to make precision therapeutics part of the expected plan for every person with health problems caused by problems with genes.
