Welcome to the Multidimensional Spectroscopy & Imaging LABoratory

who we are
We are an interdisciplinary group of physicists and physical chemists who work at the interface of experiment and theory. We like building optical spectrometers and shining femtosecond laser pulses in a dark optics lab in order to probe electronic properties of novel molecules and materials. We also like to play with toy model Hamiltonians to understand our spectroscopy through analytic theory and computation. We also leverage our expertise in inventing applied optical devices for sensing and imaging.

questions that excite us
Our group develops advanced spectroscopic techniques and quantum dynamical models to probe questions such as how does an exciton dissociate to yield charge carriers, why is this yield efficient in certain materials versus poor in others, why do natural photosynthetic proteins have near unity quantum efficiency of charge carrier generation, can slow nuclei and fast electrons couple to enhance energy and charge transfer, can quantum coherences promote this phenomenon, can natural photosynthesis guide the design of new photovoltaics with improved charge generation, etc. We are also very interested in the applied aspects of spectroscopy such as inventing better sensing and imaging tools.
Visit our publications page to learn more about such questions and (some of) our recent insights.
research theme
Discovering new phenomenon to refine existing theoretical models necessarily requires inventing experiments that surpass the state-of-the-art.
With our specialized optical spectrometers, we strive to gain a fundamental understanding of the quantum dynamics of energy and charge transport in emerging energy harvesting and storage technologies. Such technologies depend on materials such as organic polymers and singlet fission materials, inorganic perovskites, quantum dots and layered 2D materials. Femtosecond timescales are the natural scales to probe the initial steps of energy and charge transfer phenomena that eventually govern the performance of these technologies. We are also interested in applying our expertise in inventing better sensing, imaging and diagnostic tools.
Typically all projects in our group involve both, experimental and theoretical components. Visit our research page or directly contact us to know more about our current research directions.
