News
New! Applications are invited for a 3year postdoctoral fellowship in mathematical neuroscience to work with Professor Paul C. Bressloff at the University of Utah. This position is jointly funded by the NSF and the Department of Mathematics.
Candidates should hold a Ph.D. in mathematics or theoretical physics, and have some experience in numerical methods/scientific computing.
The initial focus of the research program will be neural field theory and models of visual cortex. However, there is also scope to work on stochastic models in molecular and cellular neurobiology.
Applications must be completed through the general website for postdoctoral positions, www.mathjobs.org/jobs/Utah. A complete application includes a cover letter, CV, publication list, research statement, teaching statement, and at least three letters of recommendation (at least one of which should address the applicant's teaching). Completed applications received before January 1, 2017, will receive full consideration by the Departmental Instructorship Committee.
Informal inquiries about this posting can be made by sending an email to bressloff@math.utah.edu.
New! Elected a Fellow of the Society for Industrial and Applied Mathematics (2016)
Appointed Associate Editor of the SIAM Journal of Applied Mathematics (2015)
Plenary speaker: SIAM Conference on Nonlinear waves and Coherent Structures (2014)
Published two books for Springer (2014): Stochastic Processes in Cell Biology, Waves in Neural Media
Stochastic Processes in Molecular and Cell Biology, Statistical and Biological Physics, Mathematical Neuroscience
A major goal of our research is to understand the fundamental biophysical mechanisms underlying cellular function in health and disease. This includes both single cells and multicellular systems. Our work draws upon a wide variety of methods in applied mathematics and theoretical physics including stochastic processes, statistical physics, nonlinear PDEs, and dynamical systems theory. Applications range from molecular and cellular neuroscience to gene networks to bacterial cell polarization and quorum sensing. We are also developing new mathematical and numerical methods for analyzing complex and stochastic nonlinear systems. Current research topics include the following:
Biological processes in switching environments: diffusion in domains with randomly switching boundaries; diffusionlimited reactions; stochastic gap junctions; genetic switches; bacterial persistence in switching environments
Intracellular transport: molecular motors; synaptic democracy and axonal transport; exclusion processes; aggregation models of intracellular transport; random intermittent search;
Cell polarization: active transport in budding yeast; MT regulation in growth cones; symmetry unbreaking in fission yeast
Intracellular pattern formation: Turing mechanism and active transport; synaptogenesis in C elegans
Cellular length control: axonal length sensing, intraflagellar transport
Stochastic hybrid systems: stochastic ion channels; large deviations and pathintegrals; switching master equations
Quorum sensing: coupled PDEODE systems; stochastic models and moment closure
Neural field theory: waves in stochastic neural fields; binocular rivalry waves; symmetric bifurcations in product neural fields; laminar neural fields
