Description of Research Expertise

I am a physician scientist with an interest in the developmental biology of pancreatic endocrine cells. My current research is aimed at bridging the existing knowledge gap between the maturation of fetal beta cells and stem-cell derived beta cells. The results of this research could lead to improvements in vitro differentiation protocols and help in providing a cell replacement therapy for patients with type 1 diabetes.

Main lab projects:
1) Human pancreatic endocrine cell maturation - we use functional assays and single cell RNA seq to characterize the maturation of human beta cells in development.
2) Role of Slc38a5 in alpha cell specification and maturation in mouse development - we use mouse models to characterize the role of the glycine and glutamine transporter - Slc38a5 - in alpha cell development.

Rotation projects:
1) Single cell RNA-seq data analysis of human fetal endocrine cells
2) Characterization of alpha and beta cell maturational markers
