Research Interests

Structural Elucidation and Thermodynamic Characterization of the Mechanisms of Transporters

Current transporters include NaCT, VcINDY, and LaINDY.
Uses collective variables, driven MD simulations, the string method with swarms of trajectories (SMwST), bias-exchange umbrella sampling (BEUS), and the weighted histogram analysis method (WHAM).
Also utilizes structural modeling and bioinformatics techniques.
Provides key insight to biomedical researchers developing drugs targeting transporters and synthetic bioengineers hoping to develop custom biomachines.

Investigation of the Evolutionary Relationships between Elevator and Rocking Bundle Transporters

Involves developing from scratch a new computational framework to perform topology-corrected structural comparisons between transporters.
Also involves generating a phylogenetic tree to enable visualization of the evolutionary relationships between transporter families.
Constitutes a powerful new evolutionary context in which the fundamental similarities and differences between elevator and rocking bundle transporters and their mechanisms can be investigated and understood

Atomistic Modeling, Visualization, and Simulation of Cell-Scale Membrane Structures

Capabilities encapsulated in xMAS (Experimentally-Derived Membrane of Arbitrary Shape) Builder.
Analyzes 3D meshes derived from techniques like electron microscopy to determine placement, orientation, and number of lipid molecules.
Optimizes lipid placement using an MD-based technique, builds atomistic models using a set of lipid conformation libraries, and eliminates complex lipid clashes using an energy minimization simulation technique.
Current application is a Terasaki ramp, a structural motif from endoplasmic reticula with a complex helicoidal structure like that of a parking ramp.
Models allow the interplay between atomic-scale biochemistry and cell-scale biophysics to be probed for the first time.
