Research Interests
Our research focuses on computational structural and systems biology. We develop computational methods to model complex biomolecular systems such as proteins and protein networks. Our goal is to understand the relationship between sequence, structure, function, and evolution at the level of proteins and protein networks. The tools we use include informatics, modeling, and simulation. Our research combines prediction and analysis in modeling proteins and protein networks.
- Computational Structural Biology focuses on computer modeling and analysis of protein structures. Ongoing projects in the lab include: prediction of protein three-dimensional structure and function, modeling protein sequence-structure-function relationships, comparative and evolutionary analysis of proteins.
- Computational Systems Biology focuses on computer modeling and analysis of protein networks. Ongoing projects in the lab include: reconstruction of protein-protein interaction and regulatory networks by genomic data integration, modeling dynamics and evolution of protein-protein interaction and regulatory networks, comparative and evolutionary analysis of protein networks.
