My Research

Background Dramatic growth of biological data including genome sequences, gene expression data, large-scale protein interaction screens, and experimentally determined 3D structures of biological macromolecules (DNAs, RNAs, proteins) and their complexes has led to the increasing need for efficient computational approaches. A full understanding of these large data-sets aided by computational methods, will accelerate the path to biological discoveries, provide a number of new diagnostic and treatment tools, and initiate genomic person-specific medicine development.
Goals Within the broad research area of computational biology I intend to develop a versatile research program linking structural biology with genome research focusing on: (1) understanding of folding, (2) interactions, and (3) design of bio-molecules with desired properties and (4) genome-wide analysis and inter-genome comparison of bio-molecules and their functions leading to better understanding of life.
Methods One of the fundamental approaches for combinatorial problem solving, the randomized search paradigm underlies many of the best-performing algorithms for solving difficult computational problems from many problem domains. To elucidate the above problems, my research will employ the following computational methods: (1) efficient randomized search methods; (2) machine learning techniques for optimization; and (3) application of graph-theoretical and computational geometry methods. I will focus on three tightly related methodological goals: obtaining an improved understanding of search behavior and performance, developing better search algorithms, and applying advanced search methods to problems in bioinformatics relevant to human health. In addition, I intend to forge collaborative research interests with biologists and biophysicists.
