Electrophoresis of Polyelectrolytes in Microfluidic Devices

My passion is soft matter and so to be able to study problems in which both thermal forces and advective forces are important, I've written an in-house Multi-Particle Collision Dynamics (MPCD) code. I now spend my days applying the algorithm to interesting systems. Martin Bertrand and I are currently extended the work of Owen Hickey and I, to study the electrophoresis of polyelectrolytes in microfluidic channels.

But I don't always look at single polymers. Recently, I have been thinking about polymer brushes grafted in capillaries and polyelectrolyte brushes subject to normal electric fields and have proposed that polymer coatings in microfluidic channels may increase the separating power of Field-Flow Fractionation (FFF). I really enjoy thinking about hydrodynamic separation techniques such as FFF and hydrodynamic chromatography (HC). We have tied the different operational-modes of FFF together into a single retention theory that naturally describes HC as well and also predicts the existence of a previously unexpected separation regime. With Michel Godin's research group, we experimentally verified our predictions and studied just how important wall-induced drag can be in such systems.

When I'm not in the lab, I'm still thinking about science. I write a bi-weekly science column for the student paper, the Fulcrum, entitled What's he building in there?.
