Jacqueline Kerr, PhD
Assistant Professor, Department of Family and Preventive Medicine, UCSD
Adjunct Professor, Psychology Department and the Graduate School of Public Health, SDSU

Dr. Kerr received her PhD from the University of Birmingham, England, in 2001 studying interventions and environments that promote stair use. After 3 years in the Munich Cancer Registry focusing on quality of life and breast/colorectal cancer, she moved to Active Living Research in San Diego. Dr.Kerr is currently an associate professor at UCSD in the Department of Family and Preventive Medicine, and researcher in the Center for Wireless and Population Health Systems at the Qualcomm Institute, Calit2. Dr. Kerr’s research focuses on measurement, intervention and environmental correlates of physical activity and sedentary behavior in older adults.

Dr. Kerr works on several NIH-funded R01 projects with Dr. Jim Sallis on neighborhood correlates of physical activity in children, teens, adults and older adults, including two IPEN studies in adults and teens.

Dr. Kerr leads several NCI-funded projects collecting and processing GPS data, including developing software to aggregate and process GPS data. She has led a review and several workshops on this topic and can help researchers include GPS data in their projects with protocols for IRBs, data collection, processing, matching with GIS etc.

Dr. Kerr is PI of two NCI-funded R01 grants using machine learning techniques to classify physical activity types and sedentary behaviors from raw accelerometer, GPS and heart rate data. Annotated truth images from a SenseCam person worn camera are employed in this work and Dr. Kerr is helping to advance this field.

Dr Kerr’s expertise in physical activity and location measurement inform improved evaluation of behavior change interventions. An example is the NHLBI funded MIPARC study in Continuing Care Retirement Communities, which includes community advocacy.

Simon Marshall, PhD
Associate Professor, Department of Family and Preventive Medicine, UCSD

Dr. Marshall grew up in Zambia and in different parts of the UK (parts where the rain comes at you sideways). As his dreams of becoming a professional cyclist faded, he completed a bachelor’s degree in Sports Science at Liverpool Polytechnic (UK), followed by a master’s degree in kinesiology from SDSU. He returned to the UK in 1998 to complete a PhD in exercise psychology, followed by a post-doctoral fellowship in physical activity and public health. From 2002-2012, he served as professor of exercise and nutritional sciences at SDSU. In addition to his faculty role at UCSD, Dr. Marshall serves as associate director of UCSD's Exercise and Physical Activity Resource Center (EPARC) in the Center for Wireless and Population Health Systems. He has over 16 years of experience in designing and implementing methods for measuring and evaluating physical activity. Since 2004, Dr. Marshall’s externally funded research has focused predominantly on physical activity and exercise promotion in the Latino community. He served as principal investigator (PI) for Pasos Adelante, a Spanish language physical activity program funded by the Centers for Disease Control and Prevention (CDC), and he currently serves as PI for Academia Fit, a CDC-funded translation study of supervised, grouped-based exercise classes offered in public parks and recreation centers. He has authored over 60 articles and book chapters on physical activity and sedentary behavior, and serves on the editorial board of the International Journal of Behavioral Nutrition and Physical Activity. When not working he tries to keep up with his professional triathlete wife, Lesley Paterson, who continually reminds him that exercising in San Diego is as close to paradise as it comes.
