Tessa Calhoun

Associate Professor

The Calhoun lab’s interdisciplinary research program specializes in the application and advancement of nonlinear spectroscopy and microscopy techniques for the study of a variety of complex systems. The overarching goal in all of our work is to understand the role of environmental effects by probing electronic excited states with a specific focus on imaging dynamic interfaces. To this end, we are currently employing optical techniques such as second harmonic scattering and microscopy to probe how living bacterial membranes uptake, transport, localize and efflux small molecules, including antibiotics.
