My research is, broadly, empirical in approach and focuses on topics in health care operations management. I investigate in particular how hospitals – described by Clayton Christensen as “some of the most managerially intractable institutions in the annals of capitalism” – are affected both operationally and financially by the tremendous variability and uncertainty in patients’ service needs, and propose ways to better manage the resultant complexity. To this end, I currently have three papers on this topic (available below). The first, accepted at Management Science, shows that health care access varies depending on the workload of the service provider, with service complexity moderating this relationship. The second, in preparation for resubmission to Management Science, investigates the productivity implications of treating together patients with different levels of urgency and clinical need, finding benefits of greater specialization for planned care and pooling for emergent care. The third, resubmitted to Management Science, examines the impact on routing decisions when diagnostic uncertainty is high and decision-makers are risk averse and explores a mechanism that can be employed to reduce variability in service delivery.
