Postdoc studying neural mechanisms of attention.
Welcome! I am a cognitive and computational neuroscientist studying visual perception, attention, and representation. My research utilizes behavioural psychophysics combined with neural measures (such as EEG) and computational modeling. I am also interested in theoretical issues in perception and attention.
Since the beginning of 2026, I have been a Postdoctoral Research Fellow in the School of Psychological Sciences at Victoria University of Wellington in New Zealand, where I work with Tirta Susilo. Prior to my current position, I was a postdoc with Rachel Denison at Boston University for 3 years. I received my PhD from UC San Diego in 2022, where I worked in the labs of Viola Störmer and John Serences.
