Biography

Research Interests:

The research in our group focuses on the application and development of theoretical and computational methods with the intent of gaining an in-depth understanding of biomolecular switches. The research in our laboratory seeks to decipher the underlying principles governing cell signaling mechanisms and biomolecular interactions involving proteins and RNAs. In these endeavors, we use simulation-based approaches, and related statistical mechanics, classical and quantum mechanical methods, as a complementary tool to experiments.
