Cindy received her B.A. in Psychology and Minor in Linguistics from UC Berkeley and is a primary grad student in the PEP lab. Broadly speaking, she is interested in emotion regulation and the etiology and treatment of mental illness.

She is also intrigued by the potential interplay between emotional intelligence, access to mental health services, and stigmatization of psychopathology, especially amongst minority and rural populations. In her free time, she likes to read, draw, practice taekwondo, and attend local concerts.
