Biography

Joyabrata Mal was born in 1987 in Kolkata, India. Joy did his bachelor (B.Tech) in Biotechnology at West Bengal University of Technology. He later joined the Indian Institute of Technology, Guwahati, India for his master (M.Tech) of Technology degree in Biotechnology. During this degree, he did his specialization in Environment Biotechnology and worked on synthesis of biohydrogen from carbon monooxide. Joy got admitted into Erasmus Mundus Joint Doctorate Program on Environment Technologies for Contaminated Solids, Soils and Sediments (ETeCoS3) and started as PhD Fellow at UNESCO-IHE from October 2013. As part of program, he also carried out his PhD research at Université Paris-Est. and worked at University of Limoges under a short term scientific mission (STSM, COST Action ES1302). His research was mainly focused on developing novel methods for chalcogens (selenium and tellurium) bioremediation, bioreduction and recovery. He is currently a postdoctoral fellow in University of California Berkeley and working on selenium biogeochemistry.
