Srimal joined the lab in September 2017.
Srimal received a bachelor’s of science (2010) from University of Peradeniya, Sri Lanka and Ph.D. (2017) from University of South Carolina (Advisor: Dr. Parastoo Hashemi).
In Hashemi lab, he developed a method to simultaneously measure serotonin and histamine in vivo using Fast Scan Cyclic Voltammetry and explored how these two neurotransmitters regulate each other in the brain in healthy and diseased brain.
Srimal plans to concentrate on work with mice expressing new and improved version of enhanced visual arrestin-1. He will also participate in biochemical and behavioral studies of arrestin family to explore diverse molecular mechanisms of arrestin-mediated signaling.
