An exercise physiologist by training, my expertise is on the use of physical activity to prevent and manage chronic disease. My studies have shown that cancer survivors can benefit from exercise that reverses treatment-related side effects and symptoms. Ultimately the goal of my work is to develop safe, targeted and effective exercise programs that translate well to community settings and clinical practice so that people can make positive lifestyle choices for better long-term health.

Bryan Loy, PhD
Senior Research Associate

I joined the Winters-Stone lab in 2018 after completing a National Institutes of Health postdoctoral fellowship at OHSU that focused on complimentary and integrative health approaches for treating fatigue and gait deficits. Prior to OHSU, I earned a Ph.D. in Kinesiology (concentration in exercise psychology) from the University of Georgia. My research previously focused on measurement of perceived fatigue, and the effects and mechanisms by which exercise may reduce fatigue. The goal of this research was to learn what types of exercise reduce fatigue for what groups of people, and brain changes that cause this to occur. In my free time, I enjoy participating in all the outdoor activities that Oregon has to offer (I am an Eagle Scout) and attending concerts. I am also an avid distance runner and have completed the Boston Marathon several times.

Since obtaining my Master's degree in exercise science in 2006, I have been blessed with the opportunity to work as a project director on multiple exercise intervention studies aimed at using exercise to improve symptoms and side effects from cancer and cancer treatment, ultimately improving quality of life for many cancer survivors. I have seen firsthand what exercise can do for this population and am thrilled to continue working on these types of studies as long as possible with the ultimate goal of implementing the classes into the community for all cancer survivors to benefit from.

Since completing my Masters of Public Health degree with a concentration in Epidemiology from Boston University in 2012, I've focused my career on cancer research. My work has ranged the whole cancer spectrum, from cancer screening to cancer survivorship. I truly believe in the positive effect exercise can have in anyone's life, especially cancer survivors, and appreciate being a part of this life-transforming work.

As a Registered Dietitian with a background in health promotion and health research, I am excited to be a part of Dr. Kerri Winters-Stone's research team. My passion is improving patients' quality of life through healthy behaviors such as exercise and nutrition. I'm grateful to be a part of a team that uses exercise to advance the way that we care for cancer patients. In my spare time I frequent the Portland farmers markets and local hiking trails with my family.

Senior Research Assistant

After years of being a competitive athlete, I pursued a Master's degree in Sports Medicine-Athletic Training from Florida International University. Upon my return to Portland I have worked as an exercise specialist on several of Dr. Winters-Stone's exercise trials for cancer survivors, while also instructing exercise classes for cancer survivors outside of the research setting. As an advocate of exercise as medicine I maintain a strong base of clients with a range of acute and chronic health conditions that I train to improve their mobility, physical function and general health and wellbeing.

Research Assistant I

Following high school in Northern California, I moved to Oregon to pursue a Bachelor's of Science in Exercise Science from Linfield College. After receiving my degree, I joined this team in order to combine my passion for exercise and love of research. I firmly believe that exercise is medicine, and I am so excited to work on studies that apply this idea in order to better the lives of cancer survivors.

Research Assistant I

I graduated from the University of Oregon in June 2018 with Bachelor of Science Degrees in Human Physiology and Chemistry. I am ultimately interested in the field of medicine, but I am also passionate about contributing to the wide-reaching impact that discovery through research offers. As an Undergraduate, I worked in Dr. Li-Shan Chou's Motion Analysis Lab for two years and through this research completed my senior thesis project. I joined Dr. Winters-Stone laboratory with hopes of advancing my knowledge of, and making a tangible impact within the exercise oncology field. Outside of work, I also love to explore the outdoors. One of my most memorable adventures was backpacking through Bend, Oregon en route to summiting South Sister Mountain.
