Research Interests

I am currently interested in the atypical visual perception found in autism. My research focuses on the understanding of the atypical visual perception in autism by estimating their visual system’s internal noise using a non-invasive psychophysical approach. I am also interested in typical development.

I am a postdoctoral fellowship awardee from the Transforming Autism Care Consortium (TACC).

Keywords: autism, visual perception, internal noise, psychophysics
