Fate and Transport of Subsurface Pollutants

Dr. Pankaj Kumar Gupta has been a postdoctoral fellow at the Faculty of Environment, University of Waterloo since January 2019. The majority of his works focus on two areas: (1) understanding the occurrence of bio-geo-chemical interactions when pollutants migrate into groundwater systems; and (2) developing remediation strategies. He received his Ph.D. from the Department of Hydrology, Indian Institute of Technology Roorkee with a dissertation on “Fate and transport of LNAPL under varying subsurface conditions”. He has received an AGU Student Travel Grant (2017), JPGU Travel Grant (2018), and EXCEED-SWINDON & DAAD Germany Grant (2018). He serves as an editorial board member for SN Applied Sciences and Frontiers in Water. He has published 15+ research papers, ~20 book chapters, and two popular science articles. He has reviewed several research articles for reputed journals including RSC Advances, Groundwater for Sustainable Development,ASCE JEE, ASCE Irrigation and Drainage, Env. Sc, Pollution Research, Ecohydrology, J. of Contaminant Hydrology etc. Further, he has led many site restoration and remediation consultancy projects at polluted industrial sites in India.    Ram Naresh Bharagava is an Assistant Professor at the Department of Microbiology, Babasaheb Bhimrao Ambedkar University, India. He received his B.Sc. in Biology from the University of Lucknow, and his M.Sc. in Molecular Biology and Biotechnology from Govind Ballabh Pant University of Agriculture & Technology (GBPUAT), Pantnagar, India. He completed his Ph.D in Microbiology at the Indian Institute of Toxicology Research (CSIR-IITR), Lucknow and Pt. Ravishankar Shukla University, India. He has published one authored book and eight edited books, as well as more than 150 research publications in national and international journals of repute. His major research interests are in Biodegradation and Bioremediation ofEnvironmental Pollutants, Metagenomics and Wastewater Microbiology. His research has been funded by the University Grants Commission (UGC) and Department of Science and Technology (DST), Govt. of India, New Delhi, India. He is a life member of the Indian Science Congress Association (ISCA), Association of Microbiologists of India (AMI), Biotech Research Society (BRSI), and Academy of Environmental Biology (AEB).
