Dr. Rituraj Purohit
Research Focus
My scientific interests focus on range of issues related to structural bioinformatics. By adopting multidisciplinary approach combines first-principle physics with the analysis of biological systems such as 3-dimensional structure of proteins, protein-drug complex and nucleic acids, I would like to observe that how certain mutation alter the dynamics behavior of proteins and its interaction with other molecules. I am very much interested in molecular folding, evolution, and binding interactions, and structure/function relationships of experimentally solved structures and from computational models.
