Currently, Dr. Joy is a postdoctoral research fellow at Department of Environmental Science, Policy, & Management, University of California, Berkeley and working on Selenium biogeochemistry. Focus is being given to elucidate the mechanism of microbial Se oxidation and to examine Se oxidation in natural soil/sediment matrices under different environmental conditions. Before that, he did his master (M.Tech) in Biotechnology from Indian Institute of Technology (IIT), Guwahati, India. During his master time, he did his specialization in Environment Biotechnology and worked on biohydrogen synthesis from carbon monooxide. Joy obtained his PhD in Environmental Technology from UNESCO-IHE, Netherlands. His main research was on the development of a novel microbial synthesis process of chalcogenide nanoparticles (NPs) by combining biological treatment of selenium/tellurium (Se/Te)-containing wastewaters with biorecovery of Se/Te in the form of chalcogenides NPs (e.g. Se, Te, CdSe). He generally uses several technologies like SEM-EDX, TEM, XRD, Raman spectroscopy and XPS for characterizing biogenic nanoparticles (e.g. Se, Te) and studying their interaction with microbes. He also designed and operated various bio-reactors, e.g. UASB and sequencing batch reactor to study the continuous wastewater treatment and resource recovery to help in transferring knowledge from lab scale to large scale. As part of the PhD program, he also carried out his research at various universities including Université Paris-Est, France and Leiden University, Netherlands. His expertise also expands to nano-ecotoxicology when he worked particularly on the toxicity of biogenic and chemogenic Se nanoparticles on zebrafish embryos. He has also been awarded with a short-term research scientific mission grant (STSM, COST action ES1302, supported by Horizon 2020 European Union) and worked on extracellular polymeric substances (EPS) fingerprint characterization extracted from anaerobic granular sludge and interaction of EPS with engineered nanoparticles at University of Limoges, France. So far, he has total 8 publications in international peer reviewed journals including Bioresource Technology, J of Hazardous materials, Nanotoxicology, Env. Sci. Nano. Etc.
