We have been working in the field of computational biology and bioinformatics on protein-protein interactions and protein dynamics; specifically on:

Protein-protein interfaces: the regions where two proteins bind each other. We have extensively studied the structural (geometrical) and physico-chemical properties of interfaces. We have two interface datasets (Keskin et al, 2004 and Tuncbag et al 2009, PRINT). In these datasets, the protein interfaces are classified as Type I, II and III. She showed that as expected if two proteins are similar, they bind through similar interfaces (type I). She also emphasized that, unexpectedly, even if two proteins are dissimilar, they might still use similar type of interfaces (type II).
