Chen Zheng


Chen joined the lab as a post-doc in August 2016.

He plans to focus on work with mice expressing enhanced visual arrestin-1 to determine how far we can push the compensation for defects in rhodopsin phosphorylation with phosphorylation-independent arrestins.

He also plans to participate in biochemical and biophysical studies of arrestin-1 and other members of the arrestin family to elucidate molecular mechanisms of arrestin-mediated signaling.

Awards
