Research Interests

My research interests are concerned with understanding the life cycle of the internal tide, beginning with its production via topographic generation, interaction with mesoscale features such as eddies and jets, and eventual dissipation at small scales.

I'm also interested in the application of high order/performance numerical methods. The power of these methods opens up the solution of choice problems that are otherwise prohibitively expensive to solve.

DJLES is a MATLAB based package that finds a mode-one internal solitary wave solution to the DJL equation.

You can download it here: DJLES-1.3.tar.gz along with the user guide here: djles.pdf.

Also you can follow development at GitHub.
