We use electric fields to push molecules, materials, and interfaces into doing interesting things. Our lab studies how large static, dynamic, and bipolar electric fields influence crystallization, assembly, and environmental sensing, especially in systems where the field does more than simply drive Faradaic chemistry. We work across electrochemistry, materials science, environmental chemistry, applied physics, and scientific communication, with a bias toward creative experiments.
PROJECTS
We build simple, cheap, and creative ways to measure harmful contaminants in drinking water. Our work focuses on simple point-of-use chemical sensors for contaminants like heavy metals and PFAS, often using bipolar electrochemistry mixed with electrochemiluminescence, solid-state luminescence, molecular imprinting, and microfabrication.
We use electric fields to grow useful crystalline materials. One branch develops bipolar electrochemical liquid-liquid-solid (ec-LLS) growth of semiconductors like Ge and Si at suspended liquid metal microdroplets. A second uses huge electric fields (>1 billion V/m!) in the electrical double layer to tune molecular nucleation and control API polymorph selection.
We develop authentic research experiences for the undergraduate classroom. These projects turn real chemical problems into open-ended course modules, including complex equilibria modeling inspired by the Flint water crisis, hybrid perovskite thin-film solar cells, non-aqueous redox flow batteries, on-chip microcapillary electrophoresis separations, environmental water analysis, and other messy, real-world chemical systems.
PEOPLE
Eli Fahrenkrug
Eli received his B.S. in Chemistry from The Evergreen State College in 2011 and his Ph.D. from the University of Michigan in 2016, where he helped pioneer electrochemical methods for growing semiconductor crystals at liquid metal electrodes. His interest in electrochemistry started at Hummingbird Scientific, where he helped develop tools for watching electrochemical reactions at the atomic scale. After Michigan, he spent time as a visiting scientist at the Institute of Semiconductors at the Chinese Academy of Sciences and helped build one of the world’s highest-elevation microbreweries on the Tibetan Plateau. Eli joined Colorado College in 2017. He teaches across general, analytical, instrumental, inorganic, solid-state, snow, and environmental chemistry. In the lab, he likes growing crystals, building sensors, and making snow. Outside the lab, he co-founded the Fountain Valley Water Project, moonlights as a wedding officiant, cooks Sichuan food, hikes with his dogs Pizza and Strugi, sees live music, and pursues Type 2 and Type 3 fun.
