Dr.
Singh received his M.S. degree in Biochemistry from Calcutta
University, India. He was awarded his PhD. Degree in Molecular Biology
from Jadavpur University, India. Dr. Singh joined UCLA School of
Medicine for his post doctoral research. He currently holds dual
faculty appointment as an Assistant Professor at Charles R. Drew

Research Interests I
am interested in understanding the signal transduction pathways that
regulate cell proliferation, apoptosis and differentiation. Currently I
am investigating the role of androgens during cell differentiation
using pluripotent stem cells as model system.
