Research

The Usselman research lab is always welcoming eager, inquisitive, and motivated undergraduate and graduate students to join our multidisciplinary research team to study front-edge science.  Please email Prof. Usselman for inquiries about the many research opportunities.  

The overarching theme of the Usselman research program is to use advanced magnetic resonance and optical microscopy techniques to address bio-physical chemistry problems in the areas of chemical biology, biomaterials, and redox biochemistry.  We aim to develop novel methodologies and instrumentation that address the fundamental gap in knowledge between physical measurements and theoretical models for bio-engineered systems operating at the quantum/classical interface.  We seek to understand how quantum properties play governing roles in biological function and apply theory-driven predictions of quantum biology for multi-scale integration of cellular function.
