Biography

Diptesh Dey received his Ph.D. degree in 2017 from the Indian Institute of Science Education and Research Kolkata under the supervision of Prof. Ashwani K. Tiwari (Thesis: Quantum and Classical Dynamics for Certain Elementary Gas-Phase Reactions). From 2017 to 2019, he was an H. C. Ørsted (Marie Skłodowska-Curie Cofund) postdoctoral research fellow at the Technical University of Denmark with Prof. Niels E. Henriksen (Project: Laser Induced Control of Molecules and Chemical Reactions). He joined UCL Chemistry on 2020 to research with Prof. Graham Worth after securing the prestigious Marie Skłodowska-Curie individual fellowship (Project: Simulating Intramolecular Charge Migration on Attosecond Timescales).

Research Summary

My research interests center around the photochemistry associated with the absorption of a photon of light energy by a molecular system, with a goal to control the outcome of the chemical process. To achieve this, I follow either time-dependent quantum mechanical wave packet approach or quasi-classical descriptions, develop my own computer codes to simulate the electron and nuclear dynamics, and perform requisite electronic structure calculations. Currently, I am investigating the excited-state (non-adiabatic) dynamics to simulate: (a) intramolecular charge migration upon photoionization and (b) time-resolved photoelectron spectra.


The following keywords can describe my areas of research: Theoretical Reaction Dynamics, Gas-Phase Reactions, Correlated Electron-Nuclear Motion, Potential Energy Surface, Laser control, Reactive Scattering
