Research title: "Flow Separation and Lagrangian Coherent Structures in Complex Geometries with Discontinuous-Galerkin Methods"My current work focuses on the development of a high-order Lagrangian analysis method that is consistent in implementation and accuracy with high-order discontinuous-Galerkin fluid solvers. The method allows high-order accurate determination of distinguished coherent material flow structures that form the dynamic skeleton of unsteady separated flows, thus providing a pathway for the control of such structures.

-Advised and mentored a team of 5 undergraduate students in a summer research internship at the SDSU Computational Physics Laboratory, sponsored by the San Diego MESA Alliance and the California Space Grant Consortium.-Developed research goals for the 5-student team that led to the design and fabrication of a prototype experimental apparatus for the study of compressible flows using the shallow water analogy.-Held weekly meetings to ensure sufficient progress by the team in order to meet the overall educational goals of the program.-Gave lectures on theoretical methods including compressible flow theory, shallow water equations and the shallow water-compressible flow analogy.

-Led the development and execution, with 2 assistant coordinators, of a 1 week Research Academy for 20 local undergraduate MESA students in a program sponsored by the San Diego MESA Alliance and the California Space Grant Consortium.-Developed training material for research practices and methodologies and preparing research presentations.-Coordinated with researchers at UCSD and SDSU to provide investigative shadowing of current research projects in which the students participated in over the course of the training academy.-Coordinated an all day symposium at the end of the training academy where student participants presented their work and experience during the investigative shadowing.

I provided multiphysics modeling expertise to the mechanical seals organization.
