Ewan Davies – Counting the number of ways a gas can fill a room

Ewan Davies is a PhD student in the Department of Mathematics. His research is on graph theory, the study of connected systems of abstract ‘things’ which we call graphs. In this example the ‘things’ in the graph are particles of a gas or atoms in a molecule, and he developed a new method for understanding mathematical models in these […]

Tom Lidbetter – Being “Hunted”: how randomness can help

Tom Lidbetter is an LSE Fellow in the Department of Mathematics. His research is concerned with using game theory to analyse models of hide-and-seek such as those described above.  In particular, he developed a new theory of searching for multiple targets by considering the best randomised strategies both for searching and hiding.  For more information about Tom’s research, see […]

Bernhard von Stengel – Supermarket pricing tricks

Bernhard von Stengel goes shopping and uncovers the pricing tricks not every consumer manages to detect.  Bernhard von Stengel is a Professor in LSE’s Department of Mathematics. He teaches abstract mathematics, optimisation and game theory. He co-authored the Game Theory Explorer Software. Twitter: @bvonstengel


In the spring of 2015, the consumer magazine Which? issued a report claiming that discounts by supermarkets are often misleading. […]

5 minutes with Frank Wilczek

We were very pleased to have (Nobel Laureate) Frank Wilczek (Massachusetts Institute of Technology) visit the department and give a fantastic public lecture based on his new book to a packed Old Theatre. To view his presentation, “A Beautiful Question: finding nature’s deep design”, click here. Afterwards Andy Lewis-Pye (LSE) conducted a brief interview with Frank, to follow up […]

5 minutes with Andre Nies

Andre Nies (University of Auckland) visited our Department to present his seminar on “Interactions of computability and randomness”.  He also kindly took time out with Andy Lewis-Pye (LSE) to answer a few questions on his research, the future of algorithmic randomness and incorporating classical music into his presentations.




You’ve been doing some fascinating work on the interactions between computability and randomness. […]

Bernhard von Stengel – Supermarket offers: Bigger doesn’t mean cheaper

Our man Bernhard von Stengel has been in the news again recently, using his expertise in game theory in order to give some useful advice on how to shop. He appeared on BBC Radio 4’s PM programme because the consumer group Which? has been attacking some of the leading supermarkets over the confusing and sometimes misleading ways in which […]
