The Midwest Mathematical Biology Seminar will be a series of virtual talks on mathematical biology featuring speakers from the Midwest region and beyond. All areas of mathematical biology will be represented in the seminar series, and a goal for this seminar is to build connections and foster research collaborations.
Schedule (Fall 2025)
(All talks at 11am Eastern Time / 10am Central Time on Tuesdays)

Title: Stochastic Oscillators
Abstract: Phase reduction and isostable (or amplitude) reduction are important tools for studying synchronization, entrainment, and control of nonlinear limit cycle oscillators that arise throughout mathematical biology. Phase and amplitude coordinates were introduced classically for deterministic oscillators. The definitions of asymptotic phase, isochron, and isostable break down when oscillators are subject to stochastic forcing (noise). At the same time, there are models for biological oscillations in which the oscillations cease in the absence of noise. (Examples include excitable systems, quasicycle systems, and noisy heteroclinic cycles). In this talk I will review an approach to defining the asymptotic phase of a stochastic oscillator, as well as its isostable coordinates, by diagonalizing the stochastic Koopman operator. The talk will include a brief tutorial introduction to a stochastic oscillator toolbox developed with Max Kreider, who completed his PhD under my supervision last spring (https://github.com/MaxKreider/Stochastic_Oscillator_Workshop). The talk will also set the stage for Max Kreider's talk on synchronization and Arnold tongues for coupled stochastic oscillators scheduled for the Midwest Mathematical Biology Seminar for September 23, 2025.
