Claudia Avalos

Assistant Professor of Chemistry

Education

B.S. California State University, Chico

Ph.D. University of California, Berkeley

Postdoctoral Research École Polytechnique Fédérale de Lausanne, Switzerland

Areas of Research Interest

Research interests include solid-state nuclear magnetic resonance, electron paramagnetic resonance and NV magnetometry development and application. Research projects will be focused on using optical and magnetic resonance spectroscopies to better understand the spin physics, structure and function of photoactive materials such as ferroelectrics, perovskites and organic chromophores.
