Dr. Mani’s research seeks to understand the underlying principles of the chemical reactions that take place after molecules are ionized or absorb light, exploring how we can control them to our advantage using a combined approach of chemical synthesis, spectroscopy, and computational techniques.

Dr. Mani performed his postdoctoral work as a Goldhaber Fellow in the Electron- and Photo-Induced Processes Group, directed by John R. Miller, at the Brookhaven National Laboratory (BNL). He received his PhD from the University of Pennsylvania, under the mentorship of Sergei A. Vinogradov, where he studied how magnetic fields control molecular emissivity.

At BNL, Dr. Mani utilized pulse radiolysis, together with other methods, to investigate the nature of charges in conjugated molecules. He demonstrated that by using molecular vibrations we can gain insights into the energetics and dynamics of charged species not otherwise available. His work has potential to change our understanding of conjugated polymers in ways that could realize their promise for contributing to solar energy capture and conversion, and significantly contribute to developing a new understanding of reduction potential in nonpolar environments.

“The goal of my research is to elucidate the fundamental principles that govern the energetics and dynamics of charged and excited states in molecules and molecular assemblies, and to further exploit them for the development of new technologies in energy and life sciences.”
