Bio
I am a practicing emergency physician and an clinical investigator. I have specific training and expertise in designing and testing digital behavioral interventions, collecting and interpreting in situ digital sensor data and identifying unique mechanisms of behavior change. My primary programmatic research focus is advancing the effectiveness and reach of brief alcohol interventions with a focus on using phone sensors to infer drinking events and conversational agents to improve alcohol counseling. From 2024-2028, I currently serve as the PI on an NIH-funded study (1R01AA030986) to test the efficacy of a text message intervention, ASPIRE, designed to address cognitive and behavioral elements and modify exposure to peers that influence drinking behaviors. This trial will generate unique and critical information on a national sample of young adults not in college related to how close peer networks and activity spaces change as individuals reduce their alcohol consumption. I also have a secondary focus in studying novel methods to reduce falls in older adults, using wearable sensors and behavioral interventions to improve mobility.
