Welcome to Multidimensional Spectro-Imaging Group  [‘musig‘]

Our group develops spectroscopic techniques and quantum dynamical models to understand ultrafast energy and charge delocalization on the nanoscale. Typically all projects in our group involve both, experimental and theoretical components.

Visit our homepage or our laboratory to know more about our current projects. In case you are interested in joining our group, please email me your CV along with your research interests.
