|Biomolecular Computation Lab||Debnath Pal||Computational Biology and Bioinformatics is an interdisciplinary subject area that seeks to answer important questions in biological science exploiting multi-disciplinary expertise from various areas like Physics, Chemistry, Mathematics, Biology, Computer science and engineering. Biological questions are the central point in these studies and interdisciplinary expertise is leveraged to address specific questions. The scope of the questions could range from simple, such as, what is a protein sequence coded by a gene to questions on complex cellular mechanism and signal transductions. Given the diversity and wide range of areas that encompass this subject, each researcher focuses on a few or related questions of his or her interest. For example Prof. Debnath Pal’s laboratory currently focuses on the theme of Sequence→Structure→Function relations in biomolecules, protein in particular. The final goal is to understand the function of biomolecules in molecular and cellular context. Given that function of any biomolecule is governed by its physico-chemical features and environmental contexts, his lab approaches the problem from various angles. For example, addressing the question from the perspective of first principle, Prof. Pal’s lab is studying protein function through its correlation with molecular dynamics. The simple idea that is being investigated is that proteins are flexible molecules ─ can we find specific functional modes of motion to understand what and how proteins perform their function? The same problem is also being approached from the experimental side on a macroscopic scale through Systems Biology approaches using genomics, transcriptomics, proteomics, and metabolomics. Here molecules are being investigated to characterize them for identification, followed by understanding their modification and/or concentration in cells. The data is being used to develop models and hypothesis for biological function. On computer science side, new algorithms are being developed for better and more efficient answer to the said problems.|
