About Us | We are ultrafast spectroscopists at Yale University working to uncover how energy and charge interact with and traverse complex nanoscale environments—from proteins to quantum materials. In pursuit of this understanding, we develop and apply new forms of multidimensional spectroscopy that push the frontier of experimental capability. These approaches allow us to uniquely probe dynamical processes that span many scales (in energy, length, and time), driving transformations such as light-to-chemical energy conversion in photosynthetic systems and the emergence of new quasiparticles and phases of matter in quantum materials. Our research program aims to establish frameworks to understand and ultimately inform the design of solar conversion sources, functionally engineered proteins, and advanced-generation devices.

The Arsenault Lab is highly interdisciplinary (bridging chemistry, physics, biophysics, and materials science) and collaborative. We are always excited about new opportunities throughout the condensed phase.
