Introduction
My research is broadly in the area of Operations Management with a focus on empirical health care operations. In my research, I apply advanced empirical methods to large healthcare data sets to study the organizational determinants of decision quality in multi-stage flow systems. My research provides insights into how health providers can evolve their business processes and incorporate new technologies to meet the dual challenge of improving clinical outcomes while controlling costs.

Although medical research has addressed the clinical management of chronic opioid users, little is known about how operational interventions shortly after opioid initiation can impact a patient’s likelihood of long-term opioid use. Using a nationwide U.S. database of medical and pharmaceutical claims, we investigate the care delivery process at the...
Using data from over 300,000 visits to an emergency department (ED), we study the accuracy of gatekeeping decisions - the choices that physicians make regarding patient discharge or admission to the hospital. In our study context, we focus specifically on the effectiveness of a second gatekeeping stage in the ED - a clinical decision unit (CDU). Al...
General hospitals across the world are becoming larger (i.e., admitting more patients each year) and more complex (i.e., offering a wider range of services to patients with more diverse care needs). Prior work suggests that an increase in patient volume in a hospital service is associated with reduced costs per patient in that service. However, it...
Objective
Admission to hospital over a weekend is associated with increased mortality, but the underlying causes of the weekend effect are poorly understood. We explore to what extent differences in emergency department (ED) admission and discharge processes, severity of illness and the seniority of the treating physician explain the weekend effect...

We use a detailed operational and clinical data set from a maternity hospital to investigate how workload affects decisions in gatekeeper-provider systems, where the servers act as gatekeepers to specialists but may also attempt to serve customers themselves, albeit with a probability of success that is decreasing in the complexity of the customers...
