Welcome to Pandey Group

Interfaces play an important role in a variety of intriguing charge transfer process relevant to biology, catalysis, environmental chemistry and molecular electronics. Fundamental information about the molecules at interfaces is limited as many spectroscopic methods are not able to specifically detect the buried interface between two condensed phases. A primary goal of our research is to use the tools of ultrafast nonlinear spectroscopy to provide a comprehensive picture of interfacial structure and dynamics.
