Welcome!

I'm a Postdoctoral Scholar at UC Davis with a Ph.D. in Psychology from Johns Hopkins University.

I investigate the neural mechanisms of cognitive control, attention, and emotion in mood disorders, with a focus on interventional and clinical approaches. I apply EEG, fMRI, TMS, behavioral, and computational methods to my research. I aim to translate this work to improve clinical outcomes, digital mental health, and diagnostic accuracy. I strive to provide an excellent education for students in conjunction with my research, as a research mentor, teaching assistant, and lecturer.

After my postdoctoral position, I plan to compete for a faculty position at a research university.
