I'll give an introduction to modelling contagion processes on networks. I will discuss both biological and social contagions, and I will focus especially on the latter. I will consider what subjects like dynamical systems, statistical physics, and...

A video of this event is available on mathtube.org Experimental design is a branch of statistics focused upon designing experimental studies in a way that maximizes the amount of salient information produced by the experiment. It is a topic which has...

Lecture slidesfor this event are available on mathtube.org In this seminar we will discuss a new model for strategic investment model for a merchant energy storage facility. The facility's actions impact market-clearing outcomes, and thus it is a...

The profit obtained from operating energy infrastructure depends on fluctuating market prices. Oil production is a topical example. When oil prices are low enough, it makes sense to shut in the wells. Shutting in a well avoids producing petroleum to...

Mathematical analysts are typically a careful sort. We sweat over the tiniest details to ensure proofs are rock-solid. The advent of fast and easy to use computers revolutionized science, engineering and some areas of mathematics. Oddly though, most...

The classical theorem of Edouard Helly (1913) is a masterpiece of geometry. In the simplest form it states that if a family $\Gamma$ of convex sets in $R^n$ has the property that every $n+1$ of the sets have a non-empty intersection, then all the...

Sustained oscillations occur in complex networks in contexts as diverse as physiology, gene regulatory networks and neural networks. Despite intensive research effort, important questions remain about the sources of oscillations in large networks...

A video of this event is available on mathtube.org. Many problems in science and engineering require the reconstruction of an object - an image or signal, for example - from a collection of measurements. Due to time, cost or other constraints, one is...

In many physical processes, one is interested in mixing and obstructions to mixing: warm air currents mixing with cold air; pollutant dispersal etc. Analogous questions arise in pure mathematics in dynamical systems and Markov chains. In this talk, I...

The “language" of mathematics has been developed since the dawn of humanity to describe and comprehend the surrounding world and its phenomena. Mathematics as a science and a school subject is widely identified with the mechanical rules of algebra or...
