Academic Biography

I am a laser physicist at the Dynamic Compression Sector of the Advanced Photon Source at Argonne National Laboratory where I use a 100 J UV laser to generate shockwaves in materials in order to study their properties under extreme conditions. Born in North Carolina, I attended the University of North Carolina Chapel Hill where I received a B.S. in chemistry with a minor in computer science. I then moved to the University of Colorado Boulder where I earned my Ph.D. studying ultrafast carrier relaxation in semiconductor quantum dots and developing theory for modeling two-dimensional Fourier-transform spectra with Prof. David Jonas. Following graduate school, I relocated to Chicago where I worked with Prof. Elad Harel at Northwestern University to develop multidimensional spectroscopy methods and apply them to nanomaterials and light harvesting protein complexes. Also at Northwestern University, I worked as a postdoctoral researcher in the group of Prof. Lin Chen where I studied the electronic and vibrational dynamics of coupled chemical systems. A central theme of my research has been to use lasers and optics to study the dynamics of complex materials under extreme conditions and timescales.
