Biomathematics, Biophysics, and Bioengineering

I am an Assistant Professor at Florida State University in the Department of Mathematics and the Institute of Molecular Biophysics. I am interested in a number of topics in applied mathematics. Most of these involve applications of the theory of dynamical systems, partial and stochastic differential equations, and nonequilibrium statistical physics to problems in cell biology, synthetic biology, physiology, biophysics, collective behavior, and decision making. Here are a few of the projects on which I am interested:

Before coming to FSU I was a postdoctoral fellow at the University of Houston and Rice University, collaborating with Professors Kresimir Josic, Matthew Bennett, and Will Ott. I obtained my Ph. D. in Mathematics from the University of Utah under the supervision of Professor Paul Bressloff in 2017. Prior to that, I obtained a Bachelor of Science degree in Mathematics and a Bachelor of Science degree in Biochemistry from the University of Oklahoma in 2012.
