Garnet K.-L. Chan is currently the Hepburn Professor of Theoretical Chemistry in the Department of Chemistry, Princeton University. He is also an associated faculty member of the Physics department, and a faculty fellow of the Princeton Center for Theoretical Science. Prior to his appointment at Princeton, he was an Associate Professor of Chemistry and Chemical Biology at Cornell University. He has received a number of awards including the ACS Award in Pure Chemistry, the Medal of the International Academy of Quantum Molecular Science, the Camille Dreyfus Teacher-Scholar award, the Alfred P. Sloan and David and Lucile Packard fellowships, and the NSF CAREER award.
His research lies at the interface of theoretical chemistry, condensed matter physics, and quantum information theory, and is concerned with the phenomena and numerical methods associated with quantum many-particle systems. Some current systems of interest include metalloenzymes and biological catalysts, transition metal oxides and superconductivity, and organic molecular crystals and light harvesting. He has contributed to a wide range of quantum simulation methods, including density matrix renormalization and tensor network algorithms for real materials, downfolding through canonical transformations, local quantum chemistry methods, quantum embeddings including dynamical mean-field theory and density matrix embedding theory, and new quantum Monte Carlo techniques.
