Sudeep Bhattacharyay
  • Associate Professor
  • Chemistry and Biochemistry
  • Blugold Supercomputing Cluster

Teaching Interests
  • General Chemistry: CHEM 103, CHEM 104
  • Physical Chemistry: CHEM 433, CHEM 434, CHEM 406
  • Analytical Chemistry: CHEM 213

One of my main interests is to foster active learning through discovery-guided projects. In the past few semesters, classroom research projects have been designed and introduced in biophysical and physical chemistry courses, mostly with senior students. These projects are computational and are being carried out using either a remote server or the in-house Blugold Super-Computing Cluster.

Research and Creative Activities
  • Computational and theoretical chemistry to probe the chemistry of enzymes
  • Redox Chemistry
  • Protein Dynamics

We use theory, concepts of physical chemistry, and advanced computer simulation methods to explore these questions. In addition, we also collaborate with experimentalists to validate the theoretical findings.

Education
  • Ph.D. Indian Association for the Cultivation of Science, Jadavpur, India (Chemistry)
  • M.S. Indian Institute of Technology, Kharagpur, India (Chemistry)
  • B.S. Indian Institute of Technology, Kharagpur, India (Chemistry)
