Ida Clarke

M.S. 2022
Ida graduated with an M.S. in Environmental Engineering in 2022. She brought her experience as a former water treatment operator back to the lab. Her research focuses on organic matter removal from wastewater effluent to improve the efficiency of water reuse treatment systems. She earned a B.S. in Environmental Physical Science from Black Hills State University. She is a member of the Oglala Lakota tribe in South Dakota and her research is supported by the Tribal Climate Leaders Program of the North Central Climate Adaptation Center.

Nadia Jorgenson

B.S. 2019
Nadia is an undergraduate student in the Chemical and Biological Engineering Department participating in the 2019 CU SPUR program. Her research focuses on the selective removal of hexavalent chromium (Cr(VI)) using using novel adsorbents and ion exchange materials. The research goal is to increase capacity and selectivity for Cr(VI) removal in challenging groundwaters.

Juliette Kaplan

M.S. 2020
Juliette graduated with a M.S. in Environmental Engineering in 2020. She completed her bachelor's degree in Environmental Engineering in 2018 at the University of Colorado Boulder. Juliette worked with a local municipality and consulting firm to conduct bench- and pilot- treatment studies to support the design of a new water treatment plant. Her research investigated the use of fluorescence to model DOC removal by coagulation.
