Dr. Murphy's current primary interest is in causal inference and multi-stage decisions, sometimes called dynamic treatment regimes. Dynamic treatment regimes are individually tailored treatments involving a sequence of decision rules that specify when to alter therapy. The decision rules employ variables such as patient response, risk, burden, adherence, and preference, collected during prior therapy.
