My current primary interest is in developing data analysis methods and experimental designs aimed at improving real time multi-stage decision making in mobile health. I am particularly interested in methods and algorithms that can be employed on wearable devices, such as smartphones, to deliver individually tailored treatments. This is an area within the domain of dynamic treatment regimes; a dynamic treatment regime is a sequence of decision rules that specify when to alter the therapy and specify which intensity or type of subsequent therapy should be offered. The decision rules employ variables such as patient response, risk, burden, adherence, and preference, collected during prior therapy.
This work is or has been funded by National Institute on Drug Abuse and by National Institute of Mental Health. I work with researchers at The Methodology Center on these topics.
