Biography

 

 

Yoshiko Fujita, Ph.D.https://bios.inl.gov/Lists/Researcher/DisplayOverrideForm.aspx?ID=173Yoshiko Fujita, Ph.D.Dr. Yoshiko Fujita is a senior scientist in the Biological and Chemical Processing Department at the Idaho National Laboratory. She has served as a principal investigator on multiple projects sponsored by the U.S. Department of Energy’s Office of Science and Office of Energy Efficiency & Renewable Energy, in the areas of subsurface contaminant fate and transport, critical materials, and geothermal energy. She is the lead for the “Environmental Sustainability” thrust area within DOE’s Critical Materials Institute. Her research interests are in the area of biogeochemistry as related to water quality, with an emphasis on fundamental studies supporting the development of practical applications and approaches for implementation. A unique feature of her career has been her extensive experience in field-based research, complemented with studies at the molecular and bench-scale. During her dissertation and postdoctoral work at Stanford University, she studied changes in organic water quality during aquifer recharge by treated wastewater. At the INL, she continued her interest in field-based research but transitioned to a focus on mineral precipitation/dissolution and associated effects on inorganic contaminant fate and transport in the subsurface. More recently, she has investigated the potential for biomarkers to inform geothermal resource evaluation and studied interactions between rare earth elements and microorganisms, considering both impacts to ecological function and the prospect for microbiological approaches to enhance strategic metal recovery. <div class="ExternalClass9760950EE11E4B618D17D046B0CC0DC5"><p>​Ph.D., Civil Engineering - Stanford University</p><p>M.S., Civil Engineering - Stanford University</p><p>B.A., Chemistry - Williams College</p></div><div class="ExternalClass415B094014C146DBA20FFAC608507800"><p>​Biogeochemistry in subsurface environments and water quality</p></div><div class="ExternalClass0E4AF313CDDA4B01A40AC3A7A4A4A923">American Geophysical Union<div>American Chemical Society</div><div>American Society for Microbiology</div><div>Geochemical Society</div><div>Interpore Society<br></div></div><div class="ExternalClassF6DB335C5F924F5FA24F36034365D8E0"><div><p>Reed, D.
