dr. C. Baeumer MSc (Chris)

Assistant Professor

About Me

I am passionate about materials science education and research - at the boarder between physics, chemistry and engineering. I am driven by scientific curiosity for a fundamental understanding of materials and processes and  I believe that ground-breaking science can and should address great societal changes. Currently, my research focuses on the solid/liquid interface, in particular for electrocatalysts that enable energy conversion and sustainable synthesis of chemicals and chemical fuels. 

Besides my position at the UT, I am also an associated researcher at the Peter Grünberg Institut at Forschungszentrum Jülich in Germany.

Before joining the UT in 2020, I was a Marie Skłodowska Curie Fellow at Stanford University and RWTH Aachen University. I obtained my Ph.D in physics at RWTH Aachen University and Forschungszentrum Jülich in 2016 and my M.Sc. in materials science at the University of Illinois at Urbana-Champaign in 2013.
