Kerri Winters-Stone, PhD, FACSM
Principal Investigator

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.

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.

Research Associate

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.

Senior Research Assistant

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.

Colin Lipps, BS
Research Assistant II

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.

Senior Research Assistant 

As a longtime fitness professional with an academic background in Exercise Science, I have spent the past two decades studying individuals and groups formally and informally in various sport and fitness settings. I am currently pursuing a PhD in Kinesiology at Oregon State University, and my scholarly work focuses broadly on inclusive physical activity promotion. I believe that all people deserve access to positive and safe physical activity participation experiences, and because I am particularly interested in the development and delivery of such experiences for cancer survivors, I am grateful for the opportunity to be a part of the Winters-Stone lab. I see firsthand through our research how beneficial exercise is to cancer survivors’ overall health and wellbeing, and I am committed to contributing as much as I can toward making safe and effective exercise accessible to all survivors.

Research Assistant ll 

I graduated from Linfield College in the spring of 2017.  Immediately after, I began to work in a Physical Therapy clinic as my first post-college job experience.  Realizing that this was not the route I wanted to go, I applied and was accepted into University of Mary’s Masters in Clinical Exercise Physiology graduate program.  After 2 years at the physical therapy clinic, a job opened up that would allow me to work on my Master’s program and do research at the same time.  I joined Dr. Winters-Stone laboratory in the spring of 2019 with hopes of advancing my degree of understanding in chronic diseases and how exercise plays a role in the fight against disease and its side effects. It has been a pleasure to work in a setting that pins exercise as a pivotal aspect in health care, and a pivotal aspect in the fight against cancer.

Research Assistant II

I am originally from Corvallis, OR. I graduated from Eastern Washington University in 2007 where I obtained my B.S. in Exercise Science while playing division one basketball. I continued my journey in my passion for analyzing human movement and improving individual’s health, wellness, and wholeness by obtaining my Doctorate in Physical Therapy from Pacific University in 2018. Along the way (2014) I became a Certified Strength and Conditioning Specialist Certification. I have had the opportunity to use my background in diverse settings and populations, and I am thrilled to be a part of Kerri Winters-Stone’s team to be able to apply my passion for working with the oncology population utilizing exercise-based protocols.

Christopher Chalmers, MS
Research Assistant II

Throughout my bachelor's, I worked as a personal trainer for years, coaching a myriad of different clientele from collegiate athletes to retired veterans. After finishing my bachelor's, I worked in military physiology research, where our efforts were to improve the efficiency and safety of our soldiers. Subsequently, I proceeded to get my Master’s degree in Exercise and Sport Science at Merrimack College where my thesis focused on the effects of seated load carriage on the soldier's physical and mental performance. Now, I am fortunate to work with an amazing team at Dr. Kerri Winters-Stone’s lab, learning, and researching how exercise plays a critical role in cancer survivorship. Cancer has affected everyone to some degree, and seeing how our work positively affects cancer survivors brings me immense fulfillment.

Stephanie Krasnow, Ph.D.

After earning a Ph.D. in Physiology and Biophysics from the University of Washington, I spent a decade at the bench studying the central nervous system pathways that disrupt appetite, metabolism, and neuroendocrine function during acute and chronic illnesses. I was trained in clinical and translational cancer research by completing a Brenden-Colson Center for Pancreatic Disease fellowship and earned a certificate in Human Investigations. My research is focused on identifying predictors of treatment-related side effects and strategies to mitigate their negative impact on clinical outcomes and quality of life in cancer patients.

Deanne Tibbitts, Ph.D.
Postdoctoral Scholar

I grew up in Georgia, where I earned my bachelor’s degree in Genetics and Cellular Biology at the University of Georgia. I then moved to Portland and completed my PhD in Molecular and Medical Genetics at OHSU studying the molecular basis of leukemia and the application of targeted cancer therapeutics. I went on to complete a certificate in Human Investigations at OHSU and an NCCIH-funded clinical research fellowship in complementary and integrative health at the National University of Natural Medicine. During my fellowship, my research focused on using mind-body interventions, including trauma-informed yoga and yoga nidra, to improve emotional wellbeing. In the Winters-Stone lab, my work focuses on the use of exercise and mind-body interventions to improve psychosocial outcomes and quality of life in cancer survivors.
