David Lipshutz

Postdoctoral Research Associate
Division of Applied Mathematics
Brown University

Welcome! I'm a postdoctoral fellow in the Division of Applied Mathematics at Brown University, working with Kavita Ramanan. I completed my Ph.D. in 2013 in the Department of Mathematics at the University of California, San Diego, under the direction of Ruth J. Williams.

My research interests lie at the interface of dynamics and stochastics. In particular, I am interested in stochastic analysis, large deviations, dynamical systems with delayed dynamics and their applications to engineering and biology.

Click here for my CV (as of December 6, 2016).

I organize the Brown Probability Seminar.

Public outreach:

I participate in the Math CoOP at Brown, which is a co-operative of students, postdocs and faculty who share a common passion for math outreach and meet monthly to discuss ideas for public outreach. As a participant, I created a presentation for elementary school and middle school students that explains a card "trick'' using De Bruijn sequences, which I first saw in the book Magical Mathematics by Perci Diaconis and Ron Graham. I have also performed the card trick and given the presentation at local elementary schools in Providence, RI.
