Group Alumni


Nadia Jorgenson

B.S. Student
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. Student
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.
M. Warren

Melanie Warren

M.S. Student
Melanie graduated in May 2019 with a M.S. in Environmental Engineering (and received her Bachelor of Science in Environmental Engineering at CU Boulder in May of 2017). Her research focused on analyzing the water quality in Puerto Rico after Hurricane Maria and characterizing the challenges with lead and copper sampling protocol for drinking water distribution systems. In her spare time she likes to practice yoga, snowboard, and travel on outdoor adventures.
