My research interests lie in the analysis of nonlinear partial differential equations.

My most recent focus has been on the Navier-Stokes equations which describe the motion of a large class of viscous, incompressible fluids.

Click here and follow the links on that page for a summary of this long-standing and interesting problem.

Click here as well for a summary of my research as it relates to that problem.


Click here for news of my recent EPSRC grant success through their 'First Grant' scheme.

The grant will run from October 2015 through October 2017, and will include a workshop (date TBD) on the Navier-Stokes regularity problem.

The link also provides quite a bit of background about my research in general.
