We are all different: Modeling key individual differences in physiological systems

January 27, 2025

ANGU 347 and Zoom

Mathematical models of whole-body dynamics have advanced our understanding of human integrative systems that regulate physiological processes such as metabolism, temperature, and blood pressure. For most of these whole-body models, baseline parameters describe a 35-year-old young adult man who... Read more

Scaling limits of geodesics and upper tail asymptotics in the directed landscape

January 21, 2025

MATH 126

Two central objects in the Kardar-Parisi-Zhang universality class are the Airy process and the directed landscape. The latter can be thought of as the negative of a random directed metric space (i.e., paths are directed and have weights, which are maximized to give geodesics), and the former as... Read more

Mathematical models to untangle infectious disease eco-evolutionary dynamics across scales

January 21, 2025

Room 102: Lecture Theatre - Michael Smith Laboratories

Infectious diseases are complex systems across many scales. In this talk, I will use mathematical models to investigate a range of cross-scale questions in infectious disease eco-evolutionary dynamics. I will begin by modelling the transition from pathogen emergence to endemicity, landscapes of... Read more

A new member of the Kardar-Parisi-Zhang universality class

January 20, 2025

MATX 1100 and Zoom

A recurring theme in probability theory is that of universality: when extremely different looking systems have the same large scale statistical behavior. In the last few decades, an important new universality class has been discovered, called the Kardar-Parisi-Zhang (KPZ) universality class.... Read more

Groups with good reduction and buildings

January 20, 2025

Over the last few years, the analysis of algebraic groups with good reduction has come to the forefront in the emerging arithmetic theory of algebraic groups over higher-dimensional fields. Current efforts are focused on finiteness conjectures for forms of reductive algebraic groups with good... Read more

Phase transitions and finitary codings

January 17, 2025

ESB 2012 and Zoom

In this talk we will explore the connection between the two seemingly unrelated concepts appearing in the title. Phase transitions occur when a system undergoes an abrupt change in behaviour as a consequence of a small change in parameters. While phase transitions are evidently observed in the... Read more

Random Lipschitz functions on trees

January 16, 2025

MATH 126

A Lipschitz function on a graph G is a function f:V->Z from the vertex set of the graph to the integers which changes by at most 1 along any edge of the graph. Given a finite connected graph G, and fixing the value of the function to be 0 on at least one vertex, we may sample such a Lipschitz... Read more

Representations of the Double Dyck Path Algebra and Beyond

January 14, 2025

ESB 4133 (PIMS library)

The shuffle theorem is a celebrated result in algebraic combinatorics that identifies three objects: the Frobenius character of certain $S_n$ representations, the action of the elliptic Hall algebra on symmetric functions, and a particular combinatorial expression in terms of labeled lattice...

Community ecology of infectious disease pathogens

January 14, 2025

Room 102: Lecture Theatre - Michael Smith Laboratories

The human population presents a unique ecosystem for studying pathogen communities, with anthropogenic activities like COVID-19 lockdowns serving as large-scale natural experiments. In this talk, I begin by exploring how host immune response facilitate the invasion and persistence of novel... Read more
