Biographical Info |
Rajdeep was born and raised in Kolkata (formerly Calcutta), India. He studied geology in the undergraduate days to try something different and to fulfill his passion for nature and chemistry. After finishing both BSc and MSc degree from Jadavpur University, India he moved to the PhD program in University of Minnesota, USA. He also held a two-year post-doctoral research fellow position in Columbia University before joining Rice University as a faculty member of Earth Science in 2008. |
