Hilary Emerson, Postdoctoral Associate
Dr. Hilary P. Emerson is a Postdoctoral Associate at the Applied Research Center. She received her B.S. in Environmental Engineering from the University of Central Florida and her M.S. and PhD in Environmental Engineering and Earth Science from Clemson University. Her technical area of interest is the chemical fate and transport of the actinides within environmental systems. In addition, she has experience with field contaminant monitoring in natural systems and water treatment in developing countries through her previous efforts with Engineers without Borders.
Dr. Emerson is currently a task lead on two DOE-EM funded projects (1) “Remediation Research and Technical Support for WIPP” and (2) “Remediation Research and Technical Support for the Hanford Site” both led by Dr. Yelena Katsenovich. The first research project is for the Waste Isolation Pilot Plant (WIPP) located near Carlsbad, NM which is a transuranic waste disposal facility located more than 2000 feet below ground in the Salado salt formation. Dr. Emerson is conducting batch and mini column experiments to better understand the sorption of trivalent actinides and their analogs to WIPP-relevant minerals in order to update long-term risk assessment models for the facility. For the Hanford site, she is investigating the applicability of ammonia gas injection for remediation of uranium in the vadose zone. She is also actively mentoring students as a part of the DOE Fellows program and as coordinator for the Nuclear Regulatory Commission Scholars and Fellows programs.
