The Game of Cycles, introduced in my book Mathematics for Human Flourishing, is played on a connected planar graph together with its bounded cells, and players take turns marking edges with arrows according to a sink-source rule that gives the game a...

Functions of microorganisms like looking for nutrition and biological processes such as infection and reproduction are possible due to microfluidic motion. Developments over the past two decades in tracking and manipulation at the microfluidic level...

We prove the agent’s choice will be a locally Lipschitz function of their type in the subclass of principal-agent problems considered by Figalli, Kim, and McCann (2011). Our approach is based on the construction of a suitable comparison potential...

The Riemann zeta function plays a central role in our understanding of the prime numbers. In this talk we will review some of its amazing properties as well as properties of other similar functions, the Dirichlet L-functions. We will then see how the...

The nonlinear incidence mechanism is a more general disease transmission mechanism to fit the data in clinical observations or laboratory experiments. In a heterogeneous environment, how to describe the cognitive dispersal of individuals is also an...

Transient dynamics are referred to as those dynamics that happen on ecologically relevant timescales, in which classical modelling techniques often fail to capture. Due to the ever-changing environments and ecosystems, increased interest has been...

Habitat loss is a key component driving decreases in biodiversity and the extinction of species worldwide. Of particular concern is human-driven habitat loss, primarily through agriculture, resource extraction, and urbanization. In this talk, I will...

A revolution has been underway in wave physics in recent years based around concepts of resonance and microstructured media often coupled with periodicity. This has resulted in materials known as metamaterials that have, for instance, negative...

Gliomas are the most prevalent, aggressive, and invasive subtype of primary brain tumors, characterized by fast cell growth, strong invasion capability, and well-developed tumor vasculature. Their growth and migration in the brain is a highly complex...

Observing a sample of random variables, we wish to decide whether or not some hypothesis about the distribution of the observed sample is correct. A decision procedure for such a problem is called a statistical test of the hypothesis under...
