Prospective students and postdocs PLEASE CLICK HERE.

I am a Professor in the Department of Mechanical and Aerospace Engineering at UCSD and at Scripps Institution of Oceanography.

My research interests lie mostly in fluid dynamics and applied mathematics. I work in particular on geophysical fluid dynamics, vortex dynamics, fluid-structure interaction and asymptotics. I also have an interest in Mathematics in Industry. The Research page and its subpages give more detail about my work.

I wrote a LaTeX class file that satisfies NSF guidelines for proposals. I also wrote the Journal of Fluid Mechanics bibliography style file. See the LaTex page. Resources for mathematical software can be found on the Mathematical software page.

I am also an associate editor of the SIAM Journal on Applied Mathematics. From the website, "The SIAM Journal on Applied Mathematics is an interdisciplinary journal containing research articles that treat scientific problems using methods that are of mathematical interest. Appropriate subject areas include the physical, engineering, financial, and life sciences. Examples are problems in fluid mechanics, including reaction-diffusion problems, sedimentation, combustion, and transport theory; solid mechanics; elasticity; electromagnetic theory and optics; materials science; mathematical biology, including population dynamics, biomechanics, and physiology; linear and nonlinear wave propagation, including scattering theory and wave propagation in random media; inverse problems; nonlinear dynamics; and stochastic processes, including queueing theory. Mathematical techniques of interest include asymptotic methods, bifurcation theory, dynamical systems theory, complex network theory, computational methods, and probabilistic and statistical methods."

I am also a faculty member of the Geophysical Fluid Dynamics Program at WHOI, which runs a summer school every year. I encourage graduate students with a strong background in applied mathematics and/or fluid mechanics with an interest in GFD to consider applying.

I did my undergraduate and graduate work in Mathematics at the University of Cambridge at Queens' College. I did a postdoc at SIO and was a Research Fellow at Queens' and DAMTP. I moved to MAE in 1999. I was on sabbatical at the Laboratoire de Physique Statistique of the Ecole Normale Supérieure during 2004-2005 and at the Institut de Mécanique des Fluides de Toulouse during 2011-2012. Here is my full CV.

This is an old (1999) picture, but I like it.
