Health Outcomes Research and Clinical Epidemiology Section

The theme of the Health Outcomes Research and Clinical Epidemiology Section is that of medical decision making. We strive to conduct analyses that impact how physicians should make decisions with individual patients. Typically these analyses take the form of prediction model development and validation, health-related quality of life assessment instrument development and validation, and cost effectiveness analysis. We feel these are the approaches best suited for the promotion of personalized medicine and comparative effectiveness.

Our faculty members have diverse interests.  Each is described below.

Jarrod Dalton is a statistical bioinformaticist who specializes in machine learning approaches to medical decision support. His interests span a wide range of applications in clinical and translational medicine but generally involve interdisciplinary modeling efforts to combine information from accumulated scientific research findings and electronic health record data to better inform everyday decisions shared between doctors and patients. He is working on developing practical tools for efficient and scalable implementation of probabilistic graphical models in the health care setting, including Bayesian network models for directed networks and systems, Markov random field models for undirected graphs (e.g., social networks), and decision networks for studies in health economics.

Michael Kattan  has a general research interest in medical decision making. More specifically, his research is focused on the development, validation, and use of prediction models. Most of these models are available online, and designed for physician use, at He is also interested in quality of life assessment to support medical decision making (such as utility assessment), decision analysis, cost-effectiveness analysis, and comparative effectiveness.

Jesse Schold is a statistician and health services researcher. His interests include population studies, models for evaluating quality of care of healthcare providers, healthcare policy, access to care and models to inform individual decision-making. His work has generally been in the context of organ transplantation and end-organ disease and works with several national disease registries.
