Every day, we look out into the world and see scenes of people in motion, and make sense of these scenes by appealing to their underlying causes. We appreciate the mental lives of others, including their desires, percepts, and beliefs, and we also see these actors as solid bodies, who can exert forces and navigate themselves through a physical world. How do our minds get so much meaning from this input, and how we grow to this knowledge over development?
My work aims to get at these questions through behavioral studies of human infants, and is also deeply informed by tools and theories from computational cognitive science. My research is or has been funded by the Center for Brains, Minds and Machines, DARPA, and the NSF Graduate Research Fellowship Program.
I am committed to making science more open (transparent, reproducible, and inclusive). Part of this commitment is providing high-quality mentorship to students from all backgrounds. As a first-generation immigrant to the US who stumbled into science, I am aware that without supportive mentors, and a great deal of personal development, I would have stumbled out.
I am currently postdoctoral researcher in the Saxelab at MIT. Prior to this, I was a graduate student at the Lab For Developmental Studies at Harvard. Here's a recent CV. Thanks to Kris Brewer for the above photo, and to Natalia Vélez for the illustration!
