Present occupation

I am a Full Professor in the department of Applied Mathematics and Statistics at the Baskin Shool of Engineering at UC Santa Cruz. My main research interests are in fluid dynamics and magnetohydrodynamics applied to astrophysics and occasionally geophysics. I specialize in semi-analytical work, using a combination of "pen-and-paper" calculations with moderate-size numerical computations. I also collaborate with researchers specialized in high-performance computing of fluid dynamical phenomena and help in the interpretation of the numerical results. I am a member of the Fluid Dynamics Group of UCSC, and of the Theoretical Astrophysics at Santa Cruz (TASC) research unit. I am also on the Faculty of the GFD Summer Program (WHOI), and the founding director of the Kavli Summer Program in Astrophysics


My main research interests at the moment are:

  • Large-scale magnetohydrodynamics of the solar interior
  • Modeling large-scale flows in stellar interior
  • Modeling turbulent convection
  • Modeling shear instabilities
  • Understanding the properties of fingering convection, with applications to oceanography and astrophysics
  • Understanding the properties of double-diffusive convection, with applications to astrophysics
  • Modeling the dynamics of dust particles in proto-stellar disks

See my research page for detail.


I teach a number of classes in Applied Mathematics from the introductory undergraduate level to the advanced graduate level. See the "Teaching" section of my web-site. This year (2017-2018), I will be teaching:

In addition, I alternate teaching the graduate seminar class on Geophysical and Astrophysical Fluid Dynamics (AMS 280C) with Nic Brummell and Dongwook Lee.

Graduate students & Postdoctoral Researchers

I am currently working with 4 graduate students :

  • Sutirtha Sengupta (2nd year AMS graduate student) on "Rotating fingering convection"
  • Jayashree Sridar (2nd year AMS graduate student) on "Stratified shear instabilities"
  • Sara Nasab (3rd year AMS graduate student) on "Double-diffusive sedimentation"
  • Lydia Korre (5th year AMS graduate student, co-advised with Nic Brummell) on "The solar tachocline"

Please see the information for prospective graduate students if you are a propective graduate student interested in working with me. If you are a postdoctoral researcher with your own funding, and interested in working with me PLEASE call anytime!

Current administrative & synergestic positions




I completed my undergraduate studies in Mathematics and Physics at the University Louis Pasteur in Strasbourg, in 1996. I then decided to study abroad for a year and was awarded a Knox Scholarship by Trinity College to take part in the gruelling Part III of the Mathematical Tripos in Cambridge (UK).

I chose to stay in Cambridge for my PhD, and was awarded an Isaac Newton Studentship to study "The dynamics of the solar tachocline" with Prof. D. O. Gough (Institute of Astronomy, Cambridge) and Prof. N. O. Weiss (Department of Applied Mathematics and Theoretical Physics, Cambridge). I completed my PhD in 2001, and stayed in Cambridge for my post-doc for another 4 years, funded by fellowships from New Hall (now Murray-Edwards college) and the Particle Physics and Astrophysics Research Council (PPARC). During my PPARC fellowship I had the opportunity to apply for a position at UCSC, and was delighted to be offered the job.

Since arriving at UCSC in 2004, I was awarded an NSF CAREER grant to study the evolution of magnetized stars. I was tenured in 2010, and became a Full Professor in 2012. See my Publication Page for a list of my papers.
