Dr Lauren Jarocha

Biography

Currently, I’m working as a PDRA in a joint collaboration between the Hore, Mackenzie, and Timmel groups in the Department of Physical and Theoretical Chemistry. I completed my PhD with Prof. Malcolm Forbes at the University of North Carolina at Chapel Hill in 2014, with a focus on using transient and steady state electron paramagnetic resonance techniques to study the effects of nanoscale confinement on radical pair chemistry. My undergraduate work was done at Carleton College in Northfield, MN.

Research interests

My general research interests are radical pair chemistry, photochemistry, optical spectroscopy, and magnetic resonance.

My current research project is at the intersection of physical chemistry, biochemistry, and spectroscopy. In order to try to identify and understand the chemical basis for magneto-sensitivity in animals, we investigate de novo proteins designed to produce magnetically sensitive radicals through photo-induced electron transfer, with the aim of modelling the fundamental physical behaviour observed in naturally occurring proteins. This work also includes developing new cavity enhanced absorption spectroscopies for studying photochemistry in condensed phase, biological samples.

Teaching

Physical Chemistry courses for all years, including atomic and molecular spectroscopy, magnetic resonance, and thermodynamics related to liquid and soft condensed matter
