About
Dr. Sandeep Singh Shekhawat is a Postdoctoral Fellow at the Institute for Water and Wastewater Technology, Durban University of Technology, South Africa. His research focuses on water quality, wastewater treatment, and the safe reuse of treated effluents, with particular emphasis on microbial adaptation and resistance to disinfection processes.
He earned his Ph.D. in Environmental Engineering from the Department of Civil Engineering at Malaviya National Institute of Technology (MNIT) Jaipur in 2021. He also holds a Master of Science in Biotechnology from the University of Rajasthan and a Master of Technology in Disaster Assessment and Mitigation from MNIT Jaipur. He has qualified several national-level competitive examinations in India, including GATE, CSIR-NET, and ICAR-NET.
Dr. Shekhawat’s research investigates chlorine- and UV-resistant bacteria in treated wastewater, post-disinfection microbial regrowth, antimicrobial-resistant bacteria (ARB), antibiotic resistance genes (ARGs), and disinfection by-products (DBPs). His work integrates environmental microbiology, redox biology, and disinfection chemistry to better understand microbial inactivation mechanisms and adaptive resistance in water systems. He is particularly interested in advancing hybrid chlorine–UV disinfection technologies to enhance the safety and sustainability of non-potable wastewater reuse.
He has previously served as an Assistant Professor and has over five years of teaching and research experience across reputed academic institutions. He also worked as a Senior Research Fellow in the Indo–EU DST project “Saraswati 2.0: Identifying Best Available Technologies for Decentralized Wastewater Treatment and Resource Recovery for India” at MNIT Jaipur.
Dr. Shekhawat has authored multiple SCI/Scopus-indexed research articles and a book chapter, and he actively contributes as a peer reviewer for international journals. He has presented his work at national and international conferences and received the First Position (Flash Talk Award) at the BSAEH-2021 international conference.
His current research aims to develop mechanistically informed hybrid disinfection strategies that limit microbial regrowth and antimicrobial resistance dissemination from treated wastewater, supporting resilient and sustainable water reuse systems.
