Arnab Mukherjee did his BSc from Jadavpur university, Kolkata in 1998. He then joined Indian Institute of Science, Bangalore as an integrated PhD student in chemical sciences. He completed his PhD from S. S. C. U. department of IISc Bangalore in 2005 under the supervision of Professor Biman Bagchi. Dr. Mukherjee then went for his postdoctoral research in Ecole Normale Superierure, Paris, France from 2005 to 2007 and then to University of Colorado, Boulder from 2007 to 2009. He joined IISER Pune as an assistant professor in November, 2009. He became associate professor in 2015 and full professor in 2021.

Research

Computational Chemistry and Computational Biophysics

The research interest of Prof. Arnab Mukherjee is computational chemistry and biophysics in various topics ranging from drug-DNA intercalation, DNA structural change, single water entropy, protein folding and protein-DNA binding, dynamical recrossing and internal friction in proteins and machine learning. He also collaborates with experimental colleagues in various projects such as synthetic ion channels, spectroscopic investigation of molecular recognition, etc.
