 Jordan Pommerenk

Jordan is leading the development of MonteCarlo algorithms and their application to liquidvapor systems. Current project goals include:
 Compare the accuracy and convergence of various algorithms at predicting the density of states for squarewell fluid.
 Formulate and develop new algorithms, as well as, make significant/substantial modifications to existing algorithms.
 Apply histogram methods to multiple ensembles including both canonical and grandcanonical.
Jordan is also studying the adsorption of gasses into adsorbates such as metalorganic frameworks
 Kirstie Finster
 Kirstie is exploring the fluidsolid phase diagram of a WeeksChandlerAnderson (WCA) fluid. A WCA fluid is a model fluid with a softsphere potential in which the spheres, or "atoms", exhibit repulsion, but no attraction. She is using code that applies Soft Fundamental Measure Theory (SFMT), a classical density functional theory for soft spheres, to the WCA fluid to investigate crystallization.

 Jin Kiatvongcharoen
 Continuing the work on the dynein motor protein. He is implementing a Monte Carlo analysis that is more efficient than the brownian dynamics.
 Jacob Vande Griend
 Grand canonical broad histogram methods.
Alums
 John Waczak
 John is studying the dynein motor protein. He is working to determine the values of physical parameters for the 2 dimensional simulation of the dynein protein.
 Cade Trotter
 Twodimensional grand canonical broad histogram methods.
 Sean McDonough
 Studied the hydrodynamics of surfboards.
 Lahiru Fernando
 A thermodynamics description of economics
 Elliott Capek
 Elliott is working on a Brownian dynamics simulation of a model of the dynein motor protein. The goal of this project is to test if a prestroke/poststroke hypothesis for stepping is sufficient to explain how dynein walks. The project involves deriving motion equations for a simplified dynein model, writing C++ simulation code, then fitting model parameters to experiment.

 Eric Krebs

Ph.D. 2015
Theory of inhomogeneous fluids
Eric began at Oregon State in the fall of 2010, and began by working on a classical density functional for water. He improved our functional for water to benefit from Jeff's work on the hardsphere distribution function at contact. He also worked on developing a functional based on Soft Fundamental Measure Theory for notquitehard spheres.

Ph.D. 2015
Hard spheres within classical density functional theory and Min proteins within Escherichia Coli
Jeff has studied the inhomogeneous hard sphere fluid, and developed a functional describing the likelihood of finding spheres in contact as a function of position. He then developed a simulation of minD oscillations in bacteria, and a theory for the pair distribution function of the inhomogeneous hardsphere fluid.
