Biographical Summary

Jiamin Wan’s was trainedgraduate education is in geochemistry (Institute of Geochemistry, Chinese Academy of Science) and hydrology (New Mexico Institute of Mining and Technology) in graduate school. Since graduation, she has been working employed in the Earth Sciences Division of Lawrence Berkeley National Laboratory, and now is currently a staff Staff scientistScientist. Her research has is focused on interfacial, wetting, and capillary phenomena in geologic materials, and on bio geochemical reactions and subsurface transport of contaminants, colloids and nano-particulates. Her studies under high- pressure reservoir conditions combine pore-scale microscopy of fluid interfacial dynamics with surface spectroscopy and macroscopic interfacial measurements to understand mechanisms controlling CO2, water, and oil interactions. She currently has over 60 publications in peer-reviewed journals. She has been the lead principal investigator for many projects over the past two decades, obtaining funding through competitive peer-reviewed processes.

Research Interests

  • Colloidal and interfacial phenomenon in hydro-geological media: colloid stability, partitioning, and transport; fluid-fluid interfacial tensions under atmosphere and elevated (deep subsurface) pressures and temperatures.

  • Contaminant biogeochemistry and plume remediation: studies of reactions, transport, and remediation of contaminants including U, Cr, and I129.

  • Soil C and N transport and transformations and their impacts on C cycling: from the unsaturated zone to groundwater.

  • Geological CO2 sequestration: studies of mechanisms controlling minerals, CO2, water, and oil reactions with pore-scale microscopy, surface spectroscopy, and macroscopic interfacial measurements under the relevantelevated P-T conditions.

  • CO2 enhanced oil recovery (CO2-EOR): developing new CO2 foam systems to control CO2 mobility.

  • Hydraulic fracturing: developing new CO2-based fracturing fluids and understanding the fluids-rock interactions.
