View Profile

Dr. Das did his M.S. Medical Laboratory Technology, at Sankara Nethralaya, in an off-campus course of Birla Institute of Technology, Pilani. He then pursued his M.Phil in Genetics from University of Madras, where he was among the top five best outgoing students of the University. He completed his Ph.D in Developmental Neuroscience from Max Delbrueck Center for Molecular Medicine, Berlin-Germany. He got interested in understanding the potential of stem cells into neuronal regeneration, and did his post doctoral research in stem cells at Karolinska Medical Nobel Institute, Stockholm. He then returned to his home country and worked at Imgenex India Pvt Ltd, where he initiated stem cell related works. He then moved to Narayana Nethralaya, where he is Chief Scientist Basic Science R & D and leads a team towards the usage of stem cell in health and disease. He had previously worked for small period of time at L.V. Prasad Eye Institute, Hyderabad. He is presently recognized by Vellore Institute of Technology to be a guide for M.S. by research, M.Phil and Ph.D students from Vellore.
