Complex networks and network mining: developing graph theoretic, mathematical, and computational algorithms for efficient extraction of function from topology of complex real-world networks, such as biological, social, and technological networks.
Computational and systems biology:
studying the interplay between network topology and biological function, disease, and evolution in molecular (e.g., protein-protein interaction) networks.
Computational chemistry: protein folding; computational drug discovery and design.
