About Me

Hello! I am a postdoctoral researcher in Bill Freeman’s group at MIT. I am interested in developing algorithms that learn or reason through image synthesis. Data-driven synthesis techniques have rapidly improved in recent years, and are now capable of simulating realistic faces, outdoor scenes, and even videos of human actions. I want to leverage such techniques to make models that can (1) learn by simulating hypothetical visual scenarios, and (2) causally analyze the decision processes of other vision algorithms.

I am also driven by important vision problems in applied fields, particularly medicine. Examples of my medical-related work include non-invasive vitals signs measurement from videos, and fast learning-based registration of medical images. Please take a look below at some of my projects.

I completed my Master’s (2013) and Ph.D. (2018) degrees in the EECS department at MIT, advised by John Guttag and Frédo Durand. My Ph.D. dissertation was titled Analyzing and Synthesizing Deformations in Image Datasets. My Master's dissertation focused on analyzing vitals signs from subtle body motions in video recordings.

I completed my B.S.E. (2011) degrees in Computer Science and Computer Engineering at the University of Michigan, Ann Arbor.
