Welcome to Stephen DeSalvo's home page!

My email address is [firstname][lastname]@

Currently I am a Program in Computing Assistant Adjunct Professor at UCLA (it's basically a postdoc with some teaching).  

My research interests include probability, asymptotic analysis, enumerative combinatorics, random sampling of conditional distributions, integer partitions, Poisson approximation (Stein's method)and local central limit theorems. 

I also have an extensive applied mathematics background, see Mathematical and Biological Applications.  I have been teaching using the new C++11/14 ISO Standard, and I have worked with MPI (message passing interface) for parallel computing; B-spline interpolationspatial fuzzy c-means clustering, and other image processing techniques in Matlab; orbital mechanics, specifically, the restricted 3-body problem and the invariant manifolds of the Sun-Earth-S/C and Earth-Moon-S/C dynamical systems; satellite communications systems, in the form of calculating channel capacity under various forms of noise; PI3K signal transduction pathway for Dictyostelium Discoideum; I also implemented many numerical and statistical algorithms from numerical linear algebra and statistical regression analysis in MathStudio. I also recently participated in several workshops in applied mathematics: predictive policing in Providence, Rhode Island, where we looked at dispatch data to design an optimal allocation of police resources at a district level; and also a workshop for mathematical problems in industry at Duke University, where I worked with ReVon on analyzing triage data for asthma and COPD patients using various machine learning and statistical tools.

Postdoc at the University of California Los Angeles working with Igor Pak and more recently Georg Menz.
PhD in applied mathematics at the University of Southern California in 2012 under the direction of Richard Arratia
Master's degree in statistics at the University of Southern California in 2009.
I worked with Fadil Santosa as an undergraduate student in conjunction with the Minnesota Supercomputing Institute and an REU at the University of Minnesota.

Some Recent Highlights (last updated November 21, 2016):
  • New paper with Igor Pak on finding limit shapes of restricted integer partitions via bijections. 
  • New paper with Georg Menz on a quantitative local central limit theorem relevant for understanding the joint distribution of component sizes in a random combinatorial structure.
