areas of research broadly focus on economics of health
information/information technology (HIT) and medical
applications of decision theory.
As an example to my health information and HIT work, I worked on research problems around i) the design of payment models to incentivize the adoption of technology, ii) the impact of technology adoption on operations and outcomes, and iii) relationship between information sharing, guideline design, and physician behavior.
My work on clinical decision making relates to interactions between medical decisions and health policy. As part of my work in medical decision making, I developed an interest in using analytics and data mining to create predictive algorithms in helping physicians make better decisions. I am a strong believer in data-driven decision making playing a significant role in delivery of health care in the future. Therefore, to me, identifying factors that mediate the conversion from information to knowledge to wisdom is critical.
I enjoy interdisciplinary
research and have closely collaborated with researchers from
various disciplines including economics, computer science,
bioinformatics, medicine. Because of the interdisciplinary
nature of my work, besides publishing in management journals, I
also publish in clinical and medical-informatics journals on the
broader subjects of cost-effectiveness, comparative
effectiveness, and analytics in healthcare.
research was recognized by various organizations including
INFORMS Decision Analysis Society, INFORMS Information Systems
Society, and Workshop on Health Information Technology and
