Kristin (Taylor) Bosworth
Current MD-PhD Program Student
Bio
Bio: I am a first-generation college graduate from a rural and low–socioeconomic status background; these experiences have strongly shaped my commitment to equity in medicine and research. I chose to pursue the MD–PhD pathway to bridge clinical care with rigorous research, particularly to address gaps faced by underserved and marginalized populations. My training has been guided by a desire to not only care for patients, but also to generate evidence that meaningfully improves health systems, clinical practice, and patient experiences. As a physician-scientist, I aim to integrate community-engaged research with compassionate, patient-centered care.
Clinical Interests
My clinical interests have a strong emphasis on caring for people with complex psychosocial needs, including those affected by substance use disorders, dementia, and serious mental disorders. I am particularly drawn to mental health care because of its capacity to directly change and improve the daily lives of people, integrate behavioral health, end-of-life care, and preventive services. My background and training have reinforced the importance of meeting patients where they are and addressing both medical and social determinants of health.
Research Interests
My research interests encompass a handful of topics: substance use disorders, dementia, end-of-life care, and the use of health technologies (e.g., mobile applications, virtual reality, and EHR-based tools) to improve care delivery and patient outcomes. When I was eleven, my mother was seriously injured after being rear-ended by an intoxicated driver. This experience shaped my understanding of the broader impact of substance use on individuals and families. Over time, my early questions about the circumstances of the accident, the support available to the driver, and how such harm might be prevented evolved into a lasting academic and professional interest in alcohol and substance use, guiding both my research trajectory and my decision to pursue medicine. Currently, my PhD work is focused on developing new digital health interventions for alcohol use in heavy-drinking young adults (18-25 years old).
Extracurricular Activities / Hobbies
I am deeply involved in mentorship, teaching, and advocacy. I mentor undergraduate and graduate students from disadvantaged and underrecognized backgrounds, as well as providing individualized academic support to graduate and medical students. I hold multiple leadership roles, encompassing service on trainee and student governance bodies such as MU’s Graduate Professional Council (GPC), as well as university-level committees including the Student Conduct Committee, Student Fee Review Committee (SFRC), and Student Organization Allocation Committee (SOAC). Further, I have chaired committees within national and international research organizations, including NAPCRG. I was tapped in 2025 for the Rollins Society, an organization that recognizes graduate and professional students who display exceptional leadership and service.
Outside of my academic and professional work, I am a very artistic person and enjoy painting and drawing as creative outlets. In addition, I am an avid video game enthusiast and value gaming as a way to relax and stay socially connected with friends.

Mikayla Fraunfelder
Current MD-PhD Program Student
Bio
Bio: I grew up in Portland, Oregon, where I first developed an interest in science and math during high school as a member of our Science Olympiad team. As an undergraduate student at the University of Washington, my wonderful research mentor encouraged me to think about my bench research and medical disease simultaneously. It was as an undergraduate student that I realized the need for physician scientists in medicine, and I began my journey as an MD/PhD.
Research Interests
I began my PhD in Shiyou Chen’s lab at the University of Missouri in 2021, where I developed a fascination with abdominal aortic aneurysm (AAA). AAA is a serious cardiovascular condition where the largest blood vessel in the body, the aorta, stretches and inflames. Patients with AAA are at risk of rupture and bleeding out if AAA goes untreated. Despite the surgical advancements in AAA treatment, we still don’t fully understand what causes the disease nor do we have many medicines to prevent it. I am dedicated to better understanding the molecular mechanisms of AAA formation in the hopes of identifying novel drug therapies that might treat and even reverse the disease.
Clinical Interests
I am interested in matching into Vascular Surgery, where I hope to learn more about the surgical and medical management options for abdominal aortic aneurysm (AAA) and have the opportunity to work directly with the patients my research might affect.
Extracurricular Activities/Hobbies
