Research Interests

I employ theory, modeling, and computer simulations to explore properties and function of biological and engineered molecular systems. My research addresses a broad range of topics, including (but not limited to):

Protein dynamics and function, broadly taken
Allosteric regulation in biomolecular complexes
Protein-ligand and protein-protein interactions
Molecular recognition and signal transduction
Computer-aided drug design and screening
Energy transduction in protein machines
Biological charge transfer reactions
Molecular electronics and biomolecular engineering
Bioinformatics, cheminformatics, large-scale data mining and analysis
Development of novel methods and software

Molecular Modeling and Simulations Software that I have developed

NEW: Pathways plugin version 1.1 for VMD. Pathways identifies, visualizes, and animates dynamics of dominant electron transfer pathways in biomolecular structures, and analyzes statistics of the electronic coupling fluctuations. See an example animation of pathway dynamics in ruthenated wild type azurin (1BEX) (J. Comp. Chem. 33, 906-210 (2012)).
Updated: Meadionize plugin version 1.2 for VMD. Meadionize employs the MEAD program package for calculating electrostatic potential maps and uses the maps to place ions into potential minima.
Autoionize plugin version 1.2 for VMD (included in VMD). Autoionize randomly places counter-ions in solvent around biomolecular structures.
Membrane plugin version 1.1 for VMD (included in VMD). Membrane generates lipid bilayer structures too be used in membrane protein simulations.
Namdplot, a tool for monitoring and analyzing NAMD2 output in real time (enhanced and re-implemented in Perl Namdplot utility from NAMD2).
