Research Aims

My research takes a deeply interdisciplinary approach to the study of human behavior, drawing insights and tools from social science, computer science, and statistics. Each of these fields offers a unique perspective on human behavior and the problems that arise during its examination. I have organized my early career around the belief that the advancement of scientific understanding will require individuals capable of traversing the borderland where these fields meet. In addition to serving as an interdisciplinary liaison and translator, I strive to integrate these perspectives into more nuanced and detailed wholes.

Current Projects

Automated Analysis of Facial Behavior

Facial behavior is a highly visible and informative avenue of affective and interpersonal communication. However, quantitative measurement of facial behavior using traditional observational methods (e.g., expert human coders) is expensive and time-consuming. This project focuses on developing and validating new computational methods that automate the analysis of facial expressions, head pose, and eye gaze. By drawing from recent advances in computer vision and machine learning, automated analyses can supplement or replace traditional observational methods and achieve higher levels of consistency and efficiency.

Automated Analysis of Clinical Depression

Clinical depression is associated with impairments in affective and interpersonal functioning (e.g., decreased reward processing, psychomotor disturbance, and social withdrawal) that can be detected in patterns of expressive and communicative behavior. This project focuses on applying and validating computational tools (e.g., automated analysis of facial behavior) to aid in the screening and diagnosis of depressive disorders, the tracking of symptoms over time to assess patients’ response to treatment, and the testing and refining of clinical theories regarding the mechanisms underlying depressive psychopathology.
