He is the recipient of recognitions like Expert Panel for UNEP on antimicrobial resistance, Fellow of the Royal Society of Chemistry (FRSC), Best Research Award at 4th IWA Asia Pacific Water Young Professional Conference, Global Change Research (GCR) Grant from Asia Pacific Network, DST young scientist grant, JSPS Research Fellowship, Centre of Excellence (CoE) Young Researcher Fund, and Linnaeus-Palme Grant from SIDA, Sweden. He renders the editorial service to several reputed journals. Dr. Sanjeeb Mohapatra, after fishing his Ph.D. degree at Environmental Science and Engineering Department, IIT Bombay, India, joined the National University of Singapore (NUS), Singapore, to pursue his postdoctoral research. His research interest broadly covers the monitoring of emerging contaminants (ECs), photo-degradation and enzymatic degradation of ECs, the role of dissolved organic matter in deciding the fate of such contaminants and the circular economy approach to solid waste and wastewater and sludge treatment/management. Dr. Karrie A. Weber is Director of the Microbiology and Associate Professor in the School of Biological Sciences with a joint Appointment in the Department of Earth and Atmospheric Sciences at the University of Nebraska—Lincoln. Dr. Weber is also a Fellow of the Daugherty Water for Food Global Institute and member of the Child Health Research Institute. Dr. Weber completed her Ph.D. at the University of Alabama and continued postdoctoral training in the Department of Microbiology at Southern Illinois University and the Department of Plant and Microbial Biology at the University of California at Berkeley. Following her postdoctoral training Dr. Weber held a professional research position at the University of California at Berkeley before starting her position at the University of Nebraska Lincoln. Her research has focused on the identification and description of microbial metabolic processes that couple carbon, nitrogen, and metal/radionuclide biogeochemical processes in natural and anthropogenic systems that impact human and environmental health
