Previous Experience

My first research experiences were in the synthesis and optical characterization of colloidal semiconductor quantum dots during my M.S. degree. Later, my Ph.D. was focused on the development and implementation of novel coherent spectroscopy techniques, such as MultiDimensional Coherent Spectroscopy (MDCS), that leverage ultrafast laser pulses to map out the quantum pathway of excited carriers in response to instantaneous optical excitations. After graduate school, I had a postdoctoral appointment at the University of Washington where I was awarded the ORISE Intelligence Community Postdoctoral Fellowship. During this time, I used ultrafast pump-probe experiments to measure unique aspects of exciton magnon coupling in two-dimensional magnetic semiconductors.

Professional Interests

The Diederich lab uses optical spectroscopy techniques to simultaneously measure and influence the electronic, magnetic, and temporal behavior of quantum materials at the very smallest length scales (one billionth of a meter!) and the fastest time scales (one millionth of one billionth of a second!). We are interested in how quantum phenomena that occur at these scales can be made accessible on the macroscopic scale and implemented into functional quantum devices that can enable the next generation of information storage and processing, energy harvesting, and quantum simulations. We aim to achieve this goal by working alongside world leading materials scientists, experts in the fabrication of nanoscale quantum devices, and theorists who specialize in the simulation and prediction of optical interactions with quantum materials. This collaborative approach allows us to explore the rich landscape of physical phenomena presented in quantum materials using our expertise in sophisticated optical experiments.
