Summary

Fifth year Ph.D. candidate studying chemical physics at the University of Minnesota. Research is focused on the use and development of computational methods such as molecular simulation and empirical calculations to study and design efficient separation processes. These studies have lead to a clearer understanding of the molecular-scale processes leading to separation in complex systems such as those used in chromatography as well as to the development of efficient approaches for screening of numerous (order 0.5 million) candidate setups for 2D-chromatographic separations. Other skills include ~13 years experience with computer programming and fluency in multiple programming languages; an engineer always has the right tool for the job.

Research Area [ 2010 - Current | Siepmann Group ]

My research focus is split between two areas. In the first, I make use of advanced Monte Carlo simulation in order understand the phenomena which lead to high precision separation in liquid chromatography.  From this research, insight into retention mechanisms is provided, which can then be used in directed design of future columns and for re-evaluation of long standing chromatographic theorems. My second area of focus is on coarse-grained and united-atom simulations for predictions of loading and stability in nano-structured surfactant/solvent/solute systems, with the aim of aiding formulation scientists in product tuning and design.

Research Area [ 2008 - 2010 | Potoff Group ]

Force fields were developed in order to simulate the biological fate of the post-detonation products of high energy materials as well as the removal of nerve agents via adsorbent materials found in respirators. By performing these experiments in silico we eliminate the need for many of the physical experiments on these systems which have high risk of serious injury.
