- Director of the KU Center for Computational Biology
Dr. Ilya Vakser is an expert in modeling of protein interactions and structural description of protein complexes. He is one of the authors of the FFT docking algorithm, which is a standard tool in protein docking field, and the initiator of the community-wide CAPRI protein docking competition.
Dr. Vakser earned his PhD in biophysics at Moscow State University in 1989 and received further training at the Weizmann Institute, Washington University, and the Rockefeller University. He served on the faculty of the Medical University of South Carolina as an Assistant and Associate Professor and SUNY Stony Brook as an Associate Professor. Since 2005 Dr. Vakser is the founding Director and a Full Professor at the Computational Biology (Bioinformatics) Program and Center for Computational Biology at The University of Kansas.
Molecular modeling in the context of structural genomics and bioinformatics.
The research in our laboratory focuses on molecular modeling in the context of structural genomics and bioinformatics. The major goals are to develop approaches to the modeling of protein interactions and to design procedures for reconstruction of the network of connections between proteins in a genome. The number of protein-protein interactions in a genome is significantly larger than the number of individual proteins. Moreover, most protein structures will be models of limited accuracy. Thus the structure-based methods for building this network have to be (a) fast, and (b) insensitive to significant inaccuracies of modeled structures. The precision of these methods may be correlated with the precision of the protein structures—lower for less accurate models and higher for more exact models.
Our long-term goals are to understand the fundamental principles of protein interaction and to create a structure-based description of genomes. The primary current objectives are: development of methodology for an accurate prediction of the structure of protein complexes, docking in genome-wide databases of modeled protein structures, and development of the integrated environment for docking studies.
