The primary emphasis of my work has been applications-driven empirical research in the areas of information systems economics and healthcare informatics. My research has an inter-disciplinary focus that spans multiple disciplines including management science, information systems, and operations management. My research interests can be classified into two primary areas:

  1. Healthcare Analytics and Informatics
  2. Business Value and Productivity Impact of Information Technology

Role of IT in Enabling Healthcare Delivery and Patient Care:

A recent research focus is in the measurement of the role of health information technologies and their impact on healthcare delivery and patient outcomes. My research focuses on four research themes:

  1. Estimation of the impact of health IT on cost and process quality of healthcare delivery.
  2. Development of new predictive models for predicting the propensity and timing of patient readmissions due to congestive heart failure
  3. Estimation of the impact of health IT on patient readmission risk in order to determine optimal length of stay, and
  4. Development of new econometric models to better understand patient switching behavior and estimate the impact of patient switching across hospitals on duplication rates of tests associated with outpatient visits.
