I am an engineer interested specifically in speech and vision science and its applications to machine intelligence and more generally, understanding how brains work and reason with information. I am currently pursuing a PhD at the University of Southern California where I work with an interdisciplinary group of researchers to explore the cognitive and technological aspects of speech science. My principal advisor is Dr. Shrikanth Narayanan.
