Mark Alan Fontana, PhD
Senior Director of Data Science
Dr. Fontana is an economist and Senior Director of Data Science at the Center for the Advancement of Value in Musculoskeletal Care at HSS. He is also an Assistant Professor in the Department of Healthcare Policy & Research at Weill Cornell Medical College. A digital native, his interests are interdisciplinary and empirical, focused on the intersection of health policy, machine learning, survey and experimental design, mobile health, and behavioral economics. He has an overarching interest in applying his technical and analytical skills to problems that involve large-scale computational tasks. He is fascinated by data and data collection methods not traditionally available to social scientists (spanning academic and industry sources). His work at HSS focuses on (1) collecting novel patient information through digital and mobile platforms (e.g., goals, presenteeism), (2) leveraging machine learning and large datasets to predict patient outcomes for creating pre-treatment decision-support tools and augmenting post-treatment patient monitoring (e.g., predicting patient-reported outcome measures, complications, readmissions, or running injury), (3) evaluating the effectiveness of those tools and monitoring techniques beyond simple predictive power (i.e., do they actually help patients’ downstream outcomes), (4) miscellaneous policy-related research (e.g., trends utilization of services following initial diagnosis of low back pain or osteoarthritis, or evaluating consumer-facing hospital quality rating systems), and (5) helping oversee and organize the Center’s portfolio of analytics projects (e.g., the creation of various dashboards for tracking patients). His PhD in economics is from the University of Michigan, where his dissertation investigated the pro-health impact of mobile push notifications, adaptive survey methods for measuring financial risk tolerance, and how genetic predispositions moderate the impact of cigarette tax policy. He did postdoctoral work at the University of Southern California’s Behavioral and Health Genomics Center, where his research focused on identifying genetic variants associated with behavioral phenotypes (e.g. risk-taking, depression, educational attainment), as well as supervising the design and development of a mobile platform for collecting behavioral and game data. He also has a master’s in operations research from Cornell University, where he received his bachelor’s in economics and government.
