We are mainly interested in understanding the mechanism of membrane protein function using computational approaches. We have been investigating water-transporting aquaporin channels and the related members forming the superfamily of major intrinsic proteins from different species. Another major area of research interest is to understand the molecular mechanism of recognition between proand anti-apoptotic Bcl-2 family members. We have combined sequence analysis tools, structural bioinformatics approach and molecular dynamics simulations to address the above research problems.
