I am currently looking for a new graduate student.

Undergraduate Students

Elliott Capek
Elliott Elliott is studying the dynein motor protein. He is currently working on Brownian dynamics simulations of a two-dimensional model of the dynein motor protein.


Brenden Vischer
B.S. 2016
The free energy of a liquid
Brenden studied the free energy of the square well fluid using Monte Carlo simulations.
Ryan Scheirer
M.S. 2016 Ryan
Exploring Phase Equilibrium with Statistical non-Associating Fluid Theory: A Generalized Renormalization Group Theory Approach
Billy Geerhart III
M.S. 2016
Finding the arbitrary parameter $L$ in Renormalization Group Theory via fitting Monte Carlo simulations to Statistical Associating Fluid Theory
Eric Krebs
Ph.D. 2015 Eric Krebs
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 hard-sphere distribution function at contact. He also worked on developing a functional based on Soft Fundamental Measure Theory for not-quite-hard spheres.
Austin Valeske
B.S. 2015
Determining free energies of hard sphere fluids via Monte Carlo simulation
Patrick Kreitzberg
B.S. 2015 Patrick Kreitzberg
Monte Carlo simulations for a soft sphere fluid
Michael Perlin
B.S. 2015 Michael
Optimizing Monte Carlo simulation of the square-well fluid
Josh Montegna
B.S. 2015
Determining the effective entropy of a visual hash system
Jeff Schulte
Ph.D. 2015 Jeff Schulte
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 min-D oscillations in bacteria, and a theory for the pair distribution function of the inhomogeneous hard-sphere fluid.
Daniel Roth
M.S. 2014
Applying Renormalization Group Theory to the Square Well Liquid
Paho Lurie-Gregg
B.S. 2014 Paho Lurie-Gregg
The contact value approximation to the pair distribution function for an inhomogeneous hard sphere fluid
Paho also worked on Monte Carlo simulations of hard-polyhedron fluids.
Rene Zeto
B.S. 2014
Testing the model for Min D protein oscillations in Escherichia coli
Denny Jackson
Ph.D. 2011 Denny
An Ising-like model to predict the dielectric properties of the relaxor ferroelectric solid solution $\text{BaTiO}_3\text{-Bi(Zn}_{\frac12}\text{Ti}_{\frac{1}{2}})\text{O}_3$
Chris Haglund
Switched majors to Earth Science Chris Haglund
Chris joined us in his sophomore year, and from 2011 to 2012 wrote our first Monte Carlo code to simulate the hard sphere fluid and find the probability of contact.
Murray Wade
B.S. 2012
Creating a Thermodynamics Simulation Using the Ising Model: A Microcanonical Monte Carlo Approach
Jessica Hughes
M.S. 2011 Jess
A Classical Density-Functional Theory for Describing Water Interfaces
Michael Nielson
B.S. 2010
Modeling the linear response function for broad frequency sound generation
Steve Brinkley
B.S. 2010
Measuring the Acoustic Response Function with White Noise
Jason Dagit
Computer Science M.S. 2009 Jason
Type Correct Changes—A Safe Approach to Version Control Implementation
Jason got a Masters degree in Computer Science, working on the patch theory of darcs and ensuring its proper use via type witnesses.
