In the lab, my research focus is on understanding the role of the RNA-binding protein PCBP2 in the pancreatic beta-cell using PCBP2 knock-out mouse model. During my free time, I enjoy playing Setar, spending time in nature, exercising, and watching movies.

In the lab, I study the molecular mechanism of metabolic stress response and glutamine metabolism in beta cells, with a special focus on mitochondrial transaminase "GPT2". In my free time, I enjoy spending time with my cats, cooking, and exploring hiking trails around Philly.

In the lab, I am studying the role of the RNA binding protein, poly(C) binding protein 1 (PCBP1), on beta cell survival and function. The PCBPs are a group of RNA binding proteins that regulate mRNA stability, processing, and translation that have not been widely explored in beta cells. In my free time I enjoy walking new areas in and around Philly, trying to stay in shape, and most importantly, spending time with my son and wife.


Graduate Students

I’m a PhD student in the Biochemistry and Molecular Biophysics graduate group.  My project focuses on uncovering the beta-cell specific role of ATF5, a stress induced transcription factor. I am interested in understanding the interplay of distinct transcriptional interactions that could reveal ATF5’s participation in a stress-induced transcriptional complex. Outside of the lab, I enjoy traveling the world, trying new foods, playing soccer, and reading fiction novels.
