Prof. Tessa Calhoun from the University of Tennessee will present a seminar entitled,

“Imaging Complex Systems with Ultrafast Laser Pulses”.

Abstract

Ultrafast laser pulses act as unique probes of chemical behavior and environment due to their short, femtosecond, duration and high peak power. We are exploiting these capabilities in multiple different nonlinear microscopy modalities to answer a diverse set of scientific questions in both material and biological systems. In this talk, I will first describe our work showing how the processing of a solar material alters its interaction with light. Second, I will highlight our effort to image a nonfluorescent, antifungal drug which has revealed localization inconsistent with previously proposed mechanisms of action.
