PhD Candidate in Physical Chemistry

Jonas is a Ph.D. candidate in the Chemistry Department at the University of Colorado at Boulder. He is a member of the Steven George Group in the Chemistry Department and also has a co-advisor, Victor Bright, in the Mechanical Engineering Department. His research is focused on  Atomic Layer Deposition (ALD) and Atomic Layer Etching (ALE) and their applications for MEMS devices. Jonas received his B.S. in Chemistry and Physics from Wisconsin Lutheran College in Milwaukee, WI in 2012. His undergraduate research focused on ozone for sensor and potable water applications. In his free time he enjoys snowboarding, biking, hiking, volleyball, and hanging out with his dog, Einstein.
