Tech Tuesday Talks

Tech Tuesday Talks is a monthly seminar series bringing together researchers from across the USC campus who share interest in technology-assisted health promotion and disease prevention interventions and research.  The series presents a forum to learn about one another’s work, spark collaborations as well as to introduce students to the ongoing research conducted on the USC campus which incorporates technology in health promotion.  All interested faculty and students are invited to attend.  The event is free and open to the public.

Tech Tuesday Talks are presented on the fourth Tuesday of the month in Discovery I Building, Room 140 at noon.  Lunch will be available for the first 20 arrivals and you may also bring your own lunch with you. For more information email

Speaker:  Siobhan Phillips, PhD
Assistant Professor at Northwestern University

Division of Behavioral Medicine

Feinberg School of Medicine

Topic:  Optimizing a mHealth Physical Activity Intervention for Breast Cancer Survivors

Dr. Phillips will describe the development, implementation and preliminary findings of the Fit2Thrive Study. Fit2Thrive is a mHealth intervention that uses multiphase optimization strategy (MOST) methodology to determine which of 5 intervention components are most effective and scalable for increasing physical activity among a nationwide sample (n=269) of breast cancer survivors. This study is supported by the National Cancer Institute (K07CA196840 and R21CA219028).

Siobhan Phillips, PhD, MPH is an Assistant Professor in the Division of Behavioral Medicine in the Department of Preventive Medicine at Northwestern University Feinberg School of Medicine. She received her PhD in Kinesiology from the University of Illinois Urbana Champaign and MPH in Quantitative Methods from Harvard University, and completed a postdoctoral research fellowship with the Cancer Prevention Fellowship Program at the National Cancer Institute. Dr. Phillips’ interdisciplinary research uses technology and innovative study designs to better understand the determinants and outcomes of physical activity and the biopsychosocial mechanisms underlying the relationship between physical activity and health and disease outcomes.  She seeks to develop and test physical activity behavior change interventions which can be translated into practice, with a particular focus on interventions targeting aging populations and cancer survivors.
