New degree programmes for 2017 entry!

We are very pleased to announce our new undergraduate degree programme: BSc Financial Mathematics and Statistics.  The programme is now open for 2017 entry and will provide graduates with a very strong mathematical and statistical background, combined with knowledge of economics and finance, and training in coding and computation in addition to the other, broader, elements of an LSE education. 

In addition, the new MSc Operations Reserach & Analytics course, providing students with the skills needed to apply mathematical methods to real-world analytics problems faced by companies, governments, and other institutions, is also open for 2017 entry.

November 2017: Public Lecture: Game Theory Through the Computational Lens

Date: Thursday 30 November 2017
Speaker: Prof Tim Roughgarden
Chair:  Martin Anthony

Venue: Old Theatre, Old Building, LSE

Tim Roughgarden is a Professor in the Computer Science and (by courtesy) Management Science and Engineering Departments, Stanford University, as well as a Visiting Professor in the Department of Mathematics.

The fields of computer science and game theory both trace their roots to the first half of the 20th century, with the work of Turing, von Neumann, Nash, and others.  Fast forwarding to the present, there are now many fruitful points of contact between these two fields.  Game theory plays an important role in 21st-century computer science applications, ranging from social networks to routing in the Internet.  The flow of ideas also travels in the other direction, with computer science offering a number of tools to reason about economic problems in novel ways. For example, computational complexity theory sheds new light on the “bounded rationality” of decision-makers. Approximation guarantees, originally developed to analyse fast heuristic algorithms, can be usefully applied to Nash equilibria. Computationally efficient algorithms are an essential ingredient to modern, large-scale auction designs.  In this lecture, Tim Roughgarden will survey the key ideas behind these connections and their implications.

July 2017: Summer Graduation Day

LSE graduation is always one of the best times of the year, symbolising the end of another successful academic year, and 2017 has been no exception.  We had a wonderful time celebrating with our graduates and sharing their special day with their friends and families.  We're extremely proud of all our students and wish them well in their future careers. Please do stay in touch with us via the LSE Alumni community!


Public Lecture: Weapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy

Date: 3 July 2017, 6.30pm
Speaker: Dr Cathy O'Neil
Venue: Hong Kong Thetare, Clement House, LSE

 Cathy O'Neil is a data scientist and author of the blog mathbabe.org. She earned a Ph.D. in mathematics from Harvard and taught at Barnard College before moving to the private sector, where she worked for the hedge fund D. E. Shaw. She then worked as a data scientist at various start-ups, building models that predict people's purchases and clicks. O'Neil started the Lede Program in Data Journalism at Columbia and is the author of Doing Data Science. She appears weekly on the Slate Money podcast.

We live in the age of the algorithm. Increasingly, the decisions that affect our lives - whether we get a job or a loan, how much we pay for insurance - are being made by mathematical models. In theory, this should lead to greater fairness: everyone is judged according to the same rules, and bias is eliminated. But as Cathy O'Neil reveals in this urgent and necessary book, the opposite is true. The models being used today are opaque, unregulated, and incontestable, even when they're wrong. Most troubling, they reinforce discrimination, creating a toxic cocktail for democracy.

Full details can be read here.


May 2017: And the winners are...            

Summer Term is a time for celebration and we're very pleased to announce the following winners in 2017:

May 2017: 2017 Colloquia in Combinatorics

2017 sees the eleventh year of the Colloquia in Combinatoricswhich took place on 10-11 May, hosted by QMUL and LSE.  Find out more about the event here.


Public Lecture: The response of Cambridge mathematicians to the First World War

Date: Thursday 9 March 2017
Speaker: Professor June Barrow-Green
Venue: Hong Kong Thetare, Clement House, LSE

Professor June Barrow-Green is Professor of History of Mathematics at the Open University.  She is also Visiting Professor of Mathematics at the London School of Economics.

In this lecture, Professor Barrow-Green considered how Cambridge mathematicians responded to the First World War in a variety of ways.  There were those who volunteered their mathematical skills for work at establishments such as the Royal Aircraft Factory, the National Physical Laboratory, or the Anti-Aircraft Experimental Section of the Ministry of Munitions, those who followed a military path, and those who, for reasons of conscience, refused to take an active part in the War. Professor Barrow-Green discussed the war-time activities of Cambridge mathematicians and examined the impact of the War on their careers as well as on mathematics itself.

The podcast and video of this lecture can be accessed here.


Congratulations to Drs Ewan Davies, Matthew Jenssen, Daniel Quiroz, Barnaby Roberts, Pongphat Taptagaporn and Junwei Xu!

Well done, Drs Davies, Jenssen, Quiroz, Roberts, Taptagaporn and Xu, and welcome to the department of Mathematics' alumni family!  We're so happy for you to have been awarded your PhD in Mathematics.  For details of thier theses and to view the ever-growing list of PhD alumni of the department, please view our PhD "Roll of Honour".

July 2017: EPSRC Grant Award - Dr Julia Böttcher

Dr Julia Böttcher, Associate Professor of Mathematics at LSE, has been awarded a grant from the Engineering and Physical Sciences Research Council for a project entitled  ‘Packing large-scale graphs, and graceful labellings’. Commenting on the award, Martin Anthony, Head of the Mathematics Department, said “We congratulate Julia on winning this grant. This project will address fundamental questions in the important and hugely active area of graph theory (the mathematics that underpins the study of all types of networks). Julia has made very significant contributions already, using a variety of sophisticated approaches; this grant will enable her to make even more progress on solving key mathematical questions.”

Cathy O’Neil discusses her book “Weapons of Math Destruction” in our first vlog

Cathy O’Neil visited the Department of Mathematics, LSE in July 2017 to present a Public Lecture entitled “Weapons of Math Destruction: how big data increases inequality and threatens democracy“, related to her book of the same name.  Whilst visiting, she took the time to talk with Martin Anthony and Andy Lewis-Pye (LSE Maths) about how she came to be an author, her latest book, how to define these ‘weapons’ and what the future holds.  Watch our vlog here.

Prize winners 2016/17

Congratulations to our winners of the

  • Cyril Offord Prize
  • IMA Prize

New Blog Post: Norman Biggs – History of Mathematics: The LSE Course

Norman Biggs is Emeritus Professor of Mathematics at LSE.  He is the author of 13 books and over 100 papers on Mathematics, and has also published in the fields of Numismatics and Metrology.  He is also one of the founders of our History of Mathematics in Finance and Economics course (MA318).  In his latest blog post, he writes about the course and how it came to be.  We also feature commentary from Michael Seal, a recent student on the course and winner of the British Society for the History of Mathematics (BSHM) Undergraduate Essay Prize. Read all about it here.

EPSRC Grant Award - Dr Peter Allen

Dr Peter Allen, Associate Professor of Mathematics at LSE, has been awarded a grant from the Engineering and Physical Sciences Research Council (EPSRC) for a project entitled ‘The Sparse Hypergraph Regularity Method’. Commenting on the award, Martin Anthony, Head of the Mathematics Department, said “We congratulate Peter on winning this grant. His work is characterised by its emphasis not only on solving important mathematical problems, but also on developing new insights and techniques that have deep and far-reaching consequences in many areas of mathematics. This grant will help him continue to make important advances in extremal combinatorics and related areas.”
