BIOGRAPHY

I am currently a postdoc in the Materials Research Laboratory at UCSB working under Phil Pincus. I did my graduate work under Joseph Rudnick at UCLA. I am a mathematical physicist, working in the areas of statistical mechanics, soft condensed matter, and biophysics theory.

CURRENT PROJECTS

I am currently working on three projects. With Professor Joe Rudnick, I am working on a geometric analysis of mean-field replica theories. With Professors Omar Saleh, Phil Pincus, and Y-S Jho (and others), I am working on a systematic analysis of the molecular excess, which is a simple quantity that characterizes solute/solvent associations. Finally, I am working on a project aimed at providing objective criteria for the success of maximum entropy inference methods.

RESOURCES

  • 1) Introductory slides on replica theory.

    2) A brief note on the basics of fluid mechanics -- based on course material presented by Paul Roberts at UCLA.

    3) As a 2005 summer intern at SLAC, I determined the number of beam position monitors required to completely specify the oscillation parameters of a beam packet orbiting through an accelerator storage ring. This work is presented in the report: Landy, J. SLAC-PUB SLAC-TN-05-055 (2005) [pdf]
