Barbara Bekins: Research Hydrologist specializing in modeling of transport with biological reactions. Works closely with Ean Warren to collect microbial data and formulate realistic models of microbial growth, degradation rates, and succession of microbial populations. Works with Isabelle Cozzarelli to look at chemical conditions that control microbial population shifts. Also, Barbara collaborates with Earthquake Hazards Team to model heat transport on the San Andreas and with Marine and Coastal Geology Team to model fluid pressures in the Cascadia subduction zone.

Gary Curtis: Environmental Engineer specializing in numerical simulation of organic and inorganic reactions and the interactions of the two. Works closely with Isabelle Cozzarelli to model the Bemidji field site. Also, Gary works with Jim Davis and Matthias Kohler using models to understand the sorption and transport of uranium and with Peter McMahon to understand geochemical processes at a site where chlorinated hydrocarbons are being treated with a permeable reactive barrier consisting of zero valent iron.

Hedeff Essaid: Research Hydrologist specializing in modeling multiphase flow, microbial reactions, and saltwater intrusion. Hedeff has developed two USGS computer codes: BIOMOC for modeling transport and biodegradation of subsurface contaminants, and SHARP for modeling saltwater intrusion in coastal aquifers. She collaborates closely with Bill Herkelrath to determine the correct model expressions to use for modeling multi-phase flow.
