Na+ and K+ condensation around DNA

Chromatin & DNA Modeling

DNA associates with histon proteins in higher eukaryotic cells, compactifying million-fold. The resulting chromatin fibers are very dynamic, regulating gene transcription. Using all-atom and coarse-grained molecular dynamics simulations, we are developing new insights into the chromatin fiber structure and stability.  Learn more... Haiqing Zhao, Hao Wu, Mary Pitman

Rhodopsin Cascade  

Cytoskeleton Dynamics and Cell Motility

Employing tools from non-equilibrium statistical physics, we are building models of signal transduction networks. In particular, we are interested in spatio-temporal regulation of eukaryotic cell motility. We have developed models for actin based cellular organelles, such as filopodia -- the fingerlike sensorial membrane protrusions, -- and lamellipodia -- larger flat actin-based cell motility structures Learn more...

Water in Protein Dynamics

Native Protein Dynamics

We are developing an integrated system of multi-scale computational techniques, from very coarse-grained to all-atom models, to describe the native dynamics of various enzymes and signaling proteins. In a related project, we are working on new free energy computational methods for proteins. Learn more...  Haiqing Zhao, Hao Wu
