Dr. Audrey Collins is a Postdoctoral Research Scientist in the Neuroscience Institute at AdventHealth Research Institute in Orlando, Florida. Trained as an exercise physiologist, she investigates how daily movement behaviors, such as physical activity, sedentary behavior, and sleep, are related to brain health and aging. Her research examines how time use across these behaviors throughout the day may differentially relate to markers of brain and peripheral health, with a particular interest in the role of physical activity to promote cognitive function and reduce dementia risk. Through this work, Dr. Collins aims to develop evidence-based, translational strategies that leverage 24-hour time use to optimize brain and overall health across the lifespan.

Christian Cheung is a Senior Research Scientist on the Performance Science & Health Outcomes team at WHOOP. A cardiovascular and autonomic physiologist by training, Christian earned his PhD in the Human Performance and Health Research Lab at the University of Guelph and completed postdoctoral training with the M3 Research Group at Maastricht University. His graduate and postdoctoral research examined how daily behaviors such as exercise, nutrition, and cannabis use influence cardiac autonomic function, cardiovascular health, and human performance. That focus on connecting everyday behavior to physiology is what drew him to WHOOP, where he now extends those questions from the laboratory to hundreds of thousands of people using real-world wearable data. He leads WHOOP’s COMET research program, which investigates cardiometabolic health across tens of thousands of members, spanning outcomes from blood pressure to the physiology and behavior associated with weight loss. His work sits within WHOOP’s broader effort to understand how modifiable behaviors, from physical activity and sleep to alcohol, tobacco, and marijuana use, affect physiology at population scale.

Amber Schnittjer is a Postdoctoral Scholar in the School of Kinesiology and Rehabilitation Sciences at the University of Central Florida. She earned her PhD in Translational Biomedical Sciences from Ohio University in 2026, where her research focused on sensorimotor control following anterior cruciate ligament (ACL) injury and reconstruction.

Dr. Schnittjer’s path to research was shaped by more than five years of clinical practice as a certified athletic trainer in secondary school, collegiate, and orthopedic settings. Working with patients recovering from musculoskeletal injury motivated her interest in understanding why traditional markers of recovery may not fully capture an individual’s ability to meet the demands of sport. That question has remained central to her work, from early research examining how cognitive demands influence jump-landing mechanics to her doctoral studies investigating relationships between resting-state functional brain connectivity and responses to unanticipated gait perturbations. Her long-term goal is to identify the neural mechanisms that may help explain altered movement responses following ACL reconstruction under unpredictable conditions and inform rehabilitation approaches that better prepare patients for the demands of sport.

HoWon Kim is a postdoctoral research fellow in the PRIME Laboratory at the University of Michigan and a board-certified athletic trainer. He earned dual bachelor’s degrees in physical education with a concentration in Taekwondo and sports medicine from Kyung Hee University in South Korea, a master’s degree in athletic training from Weber State University, a second master’s degree in athletic training (post-professional) from Ohio University, and a PhD in Translational Biomedical Sciences from Ohio University.

Dr. Kim’s research focuses on the neurophysiological and biomechanical mechanisms underlying persistent functional deficits after anterior cruciate ligament reconstruction and other musculoskeletal injuries, with particular emphasis on quadriceps weakness and altered movement patterns. Drawing on his clinical and research experience, he integrates neuroscience, neuroimaging, biomechanics, and athletic training to investigate how central nervous system adaptations influence recovery, performance, reinjury risk, and long-term joint health. His long-term goal is to develop evidence-based, personalized rehabilitation strategies that improve outcomes for athletes and others recovering from musculoskeletal injury.
