Biographical Summary

Sumit Mukhopadhyay is a member of the scientific staff in the Earth Sciences Division at Lawrence Berkeley National Laboratory (LBNL). Sumit received his Ph.D. in chemical engineering from the University of Southern California in 1995. After a stint of about three years at Purdue University as Research Associate, he joined LBNL in 1998 as a scientist. In 2004, Sumit was made a career member of the scientific staff. Sumit has over 60 scientific publications, about 25 of which are in peer-reviewed journals, in addition to numerous laboratory and research reports.

Sumit’s area of expertise is numerical model development and applications for coupled subsurface flow and transport processes.  He has worked in coupled fluid and heat transport processes associated with radioactive waste disposal in the unsaturated zone, numerical modeling study of reductive bioimmobilzation of Cr(VI) in groundwater, reactive transport modeling of plume mobility using a reactive facies approach, reactive transport of natural isotopic tracers in geothermal reservoirs, and subsurface sequestration of supercritical carbon dioxide. Sumit has developed methodologies for estimating the transport properties of unsaturated fractured rock from flowing fluid temperature logging (FFTL) using multiphase inverse modeling. Sumit’s research interest also includes investigation of feedback effects of reactive transport on flow in the unsaturated zone and analysis of multiphase transport processes in air-gap membrane distillation for purification of seawater.
