biography

Dr. Amar M. Singh is a research faculty member in the Department of Biochemistry and Molecular Biology at the University of Georgia. Dr. Singh received his undergraduate and graduate training at the University of Florida, and obtained his Ph.D in Molecular Cell Biology in 2006. He then went on to perform postdoctoral research at the University of Miami and the University of Georgia. He later went on to work in the biotechnology sector at Transposagen Biopharmaceuticals, Inc., prior to returning to the University of Georgia. His primary research area is in the field of mouse and human pluripotent stem cell biology, where he examines the role of signaling pathways and the cell cycle in controlling stem cell self-renewal, differentiation and heterogeneity. From his work, he has published numerous manuscripts, spoken at national and international conferences and has received many awards.
