who we are
We are an interdisciplinary group of physicists and physical chemists who work at the interface of experiment and theory.
Our daily routines are centered around playing with ultrafast optical components, electronics and femtosecond laser pulses in a dark optics lab. We also like to play with toy model Hamiltonians on a computer to understand our experiments. Alongside answering fundamental questions, we also leverage our expertise in optics and electronics to invent applied optical devices for sensing and imaging applications.
Students in the group work on projects spanning ultrafast optics and spectroscopy, theoretical modeling, optical instrumentation, and scientific data analysis, providing opportunities for students from physics, physical chemistry, applied optics, and engineering backgrounds.

questions that excite us
What fundamental photophysics make a material functional ? For example, what determines quantum transport in dissipative systems ?
Our research explores how excitons and charge carriers form, interact, and move in complex materials immediately after light absorption. These processes begin on ultrafast timescales (femtoseconds) and are governed by quantum interactions between electronic and vibrational degrees of freedom. By carefully sequencing femtosecond pulses and theoretical modeling, we investigate the fundamental physics of these dynamics in emerging materials for energy and photonic technologies.
Visit our research and publications pages to learn more about such questions and our recent insights, and our current systems of interest.
current interests
Our current interests are in studying how processes such as electron–phonon interactions, vibronic coupling, and many-body effects govern quantum transport in dissipative systems and whether these pathways can be altered by hybrid light-matter states (polaritons). These directions encompass the following -
