Dr. Prabhakar Sharma is an Assistant Professor at the School of Ecology and Environment Studies, Nalanda University. In addition to teaching a number of courses, Dr. Sharma developed an environmental laboratory for teaching and investigating engineered nanomaterials fate and transport in subsurface systems. Earlier, he served at the Department of Earth Sciences, Uppsala University, Sweden as an Assistant Professor. He was involved in teaching field and groundwater modelling related courses and performed research related to large scale CO2 sequestration through a laboratory scale setup for transport and leakage of gaseous CO2 in subsurface media, in addition, continued his research related to nanomaterial transport and retention. He had also worked at University of Western Ontario (Canada) and Ålbog University (Denmark) as a full time researcher to understand the fate and transport of nanoparticles and gaseous contaminants using column experiment and modeling through saturated and unsaturated zone. His PhD dissertation was in the area of Soil Physics and the specific research topic dealt the problems associated with movement of micro-size particles in the subsurface system (Colloid and Colloid-Facilitated Transport) at Washington State University, USA.
Teaching and research experience
Dr. Sharma has been involved with number of academic and non-academic activities and received several awards and fellowships for continuing his higher education and research activities. In his research carrier, he had supervised one PhD and several masters’ students, published more than two dozens of peer-reviewed journal articles, and received number of grants/fellowships for performing those researches. As part of his professional responsibilities, he is serving in the editorial board for Frontiers in Environmental Science and World Science Environment as well as volunteering to review 6-8 journal articles every year.
Dr. Sharma is currently leading the subsurface hydrology research related to transport and leakage of CO2 (for geological storage of CO2), fate and transport of gaseous contaminants, the role of liquid-gas interfaces on the interaction of colloids and nanomaterials, and contaminant-soil interactions for establishing a program that focuses on micro- as well as macro-scale behaviour of contaminant migration. In addition, he is involved in local and regional scale surface and shallow subsurface hydrological research through field and modeling of soil properties and subsurface water bodies using various logging techniques.
