The Dunbrack group concentrates on research in computational structural biology, including homology modeling, fold recognition, molecular dynamics simulations, statistical analysis of the PDB, and bioinformatics. In developing these methods, we use methods from various areas of mathematics and computer science, including Bayesian statistics and computational geometry. We place an emphasis on large-scale benchmarking of new methods and comparison with existing methods. We are interested in applying comparative modeling to important problems in various areas of biology. Areas of particular interest include DNA repair, proteases and other peptide-binding protein families, and membrane proteins.
Our software development uses visual programming environments, such as Visual Studio, and modern programming languages such as object-oriented C++ and C#. Our goal is to produce easy-to-use, professional software for use in our own research as well as to be distributed to other research groups around the world.
