About Me

Hi, I am a Ph.D. candidate in the Dept. of Psychology at Harvard University, advised by Prof. George Alvarez and Prof. Talia Konkle in the Vision Sciences Lab and Cognitive and Neural Organization Lab. I am grateful to be supported by the Graduate Fellowship at the Kempner Institute for the Study of Natural and Artificial Vision.

I am broadly interested in how the human mind transforms visual sensory information into meaningful percepts of the world, and whether we can use Artificial Vision models to dissect the sophisticated mechanims that biological vision uses to isolate and segment different objects in a scene. Specifically, I am exploring the tuning and spatial topographies of proto-object representations, as well as the early-mid mechanisms that lead to the emergence of an object’s global shape information.

To achieve these goals, I use a multidisciplinary approach that combines computational models of vision, primarily Deep Neural Networks, with behavioral psychophysics and neuroimaging data. By integrating these techniques, I aim to gain deeper insights into the emergent behavioral and neural signatures of mid-level computations that underlie biological vision. Here’s a brief walkthrough about my ongoing research, and you can learn more about my background and previous work on the Harvard Brain Science Initiative page.
