Research interests
I'm interested in neurocognitive mechanisms underlying reward processing, motivation, and cognitive control mediated by the midbrain dopamine system. I am currently examining individual differences in personality traits associated with depression and how these differences are manifested in the aforementioned neurocognitive functions. In particular, I use ERPs to examine the role of anterior cingulate cortex (ACC) in these functions, concerning both healthy and impaired regulation of ACC.
