Research

I am interested in the simulation of electrokinetic phenomena, namely electrophoresis and electroosmotic flow, involving polymers. Particularly I am interested in simulating systems which have yet to be explored using molecular dynamics and the sometimes surprising results of the interplay between electrostatic and hydrodynamic interactions.

I have made a number of videos (with much help from Georg Rempfer) which illustrate some of the intricacies of electrokinetics, particularly with regard to polyelectrolyte electrophoresis. They can be found here [1]
