Research interests
Working on a problem related to the stability of hurricanes...during hurricane Sandy...

My research is currently focused on understanding mixing and nonlinear stability in fluid mechanics at high Reynolds number and kinetic theory in the collisionless limit (with a specific interest in plasma physics). The rest of my work has been devoted the mathematical analysis of PDEs or variational problems arising from solid mechanics or mathematical biology and computational physics.
My research is currently funded by an NSF CAREER grant, Applied Mathematics grant DMS1462029, and a Sloan Fellowship.

Summer MAPSREU 2016
As part of the MAPS REU in the mathematics department, I am advising 5 students on projects related to mixing and dissipation in fluid mechanics. The students are working on a variety of analysis and computational PDE projects. The talented students are:
 William Golding
 Gareth Johnson
 Chloe Ondracek
 Charlie Parker
 Jenalee Reardon
We would like to acknowledge the University of Maryland supercomputing resources (http://www.it.umd.edu/hpcc) made available for conducting the research. We are specifically using resources available on the Deepthought2 cluster. I would also like to acknowledge the Sloan foundation for providing some funding related to the research.
Seminars and current topics courses
 Spring 2016: Stochastic fluid mechanincs reading course; we have worked through a variety of notes and works on the uniqueness of invariant measures for the 2D stochastically forced NavierStokes equations. Specifically, our aim was to get familiar with the work of Hairer and Mattingly on the topic.
 Fall 2015: Stochastic fluid mechanics reading course; we are mostly working through the book on 2D stochastically forceed NavierStokes by Kuksin and Shirikyan. Email me or Michele Coti Zelati...Next semester we will likely work through Hairer and Mattingly (and the works that led up to this one).
 Spring 2015: WiPs seminar: joint with the MFD group in the Courant institute at NYU, we are currently running a seminar on waves in plasma. The page can be found here ! Email LiseMarie or myself if you would like more information, or simply show up at the seminar at CSCAMM or Courant (depending on your physical location).
Teaching
I am now part of the Applied Mathematics, Statistics and Scientific Computation (AMSC) program!
If you are a graduate or undergraduate student interested in finding an REU project or PhD adviser, feel free to contact me and perhaps we can find something. I am open to advising students interested in the analysis of PDE as well as students who may also interested in doing some computation. Likely topics will be focused in some aspect of fluid mechanics or kinetic theory, tailored by the student interests, my interests, and our mutual expertises
