Biography

Ryan G. Hadt is a professor in the Division of Chemistry and Chemical Engineering at the California Institute of Technology (Caltech). He holds a Bachelor's degree from the University of Minnesota, Duluth, a Master's degree, and a Ph.D. from Stanford University. His research interests focus on Physical Inorganic Chemistry, employing a range of steady-state and time-resolved spectroscopies to understand the roles of transition metal electronic structure in interdisciplinary areas such as chemistry, biology, and physics. Hadt's current work explores the geometric and electronic structure contributions to first-row transition metal catalyzed reactions, provides insights into electron spin decoherence mechanisms relevant to quantum information science, and develops methods for sustainable drug synthesis using earth-abundant metal catalysts. He has published extensively on these topics and teaches various courses in inorganic chemistry at Caltech, guiding students through the complexities of chemical bonding and molecular dynamics.
