Research Interests:

Magnetorheological (MR) fluids are suspensions of colloids which acquire dipole moments under application of a magnetic field. Traditionally, these colloids have been used in macroscopic applications, such as controllable dampers, where the ability to tune their bulk rheological properties with a magnetic field has been exploited. We have recently shown that the microstructures formed by the colloids in thin gaps can be used to efficiently separate DNA in microfluidic devices. I am interested in studying the parameters affecting the types of structures that form in these devices. I use Brownian dynamics simulations as well as microscopy experiments to study this problem.
