Biography

Nancy is a Post Bachelors Research Associate and is currently working on her Master’s degree in Environmental Science at Washington State University Tri-Cities. She joined the lab in June 2017 as a student under the Minority Serving Institutions Partnership Program (MSIPP). Since then, Nancy’s work has included research in several programs including the Fuel Cycle Technology Waste Management Research, Deep Vadose Zone (DVZ), Immobilized Low Activity Waste (ILAW) and Nuclear Process Science Initiative (NPSI). Nancy also serves as a back-up analyst in the Environmental Sciences Laboratory (ESL) during time of need, operating instrumentation such as the ICP-OES.
