Cryptography Meets Algorithms at the AlgoUK Workshop

AlgoUKThe Foundations of Computer Science Research Group (FoCS) recently hosted world-renowned researchers in the areas of cryptography and algorithms at the AlgoUK workshop. The event, held on September 17-18 2019, attracted over 130 participants.

Adi Shamir (Weizman Institute), co-inventor of public key cryptography and Turing Award winner, talked about his recent work on understanding the fragile behaviour of machine learning systems. Madhu Sudan (Harvard), winner of the Nevanlinna and Gödel awards, talked about new constructions of "polarizing" codes for communication. Svetla Nikova (KU Leuven) talked about recent work on achieving security against powerful adversaries.

Other speakers at the two day event were Adrià Gascon (Google/The Alan Turing Institute), Mary Cryan (Edinburgh), Paul Goldberg (Oxford), Christian Ikenmeyer (Liverpool), Christian Konrad (Bristol), Daniel Paulusma (Durham) and Thomas Sauerwald (Cambridge).

Slides and abstracts for the talks are available at the workshop website,

AlgoUK Workshop in Warwick

The 4th AlgoUK workshop will take place in Warwick Sept 17 - 18, 2019.

AlgoUK is a series of UK-wide workshops, combining a UK Theory Day with a one day workshop focusing on some applications of algorithms and complexity or applied area relevant to algorithms and complexity.

Every network workshop is open to every algorithms and complexity researcher in the UK and the network itself is intended to support the whole community. There are limited funds available to assist with attendance at AlgoUK’s workshops.

Dr. Torsten Mütze joins the FoCS group and the department as a new Assistant Professor

Torsten Mutze

The Department is welcoming our new Assistant Professor Dr. Torsten Mütze, who will be associated with the Division of Theory and Foundations (FoCS) and the Centre for Discrete Mathematics and its Applications (DIMAP).

Before joining Warwick, Torsten held postdoctoral researcher positions at TU Berlin, Georgia Institute of Technology, and ETH Zürich. He obtained his PhD in Computer Science from ETH Zürich in 2011, under the guidance of Angelika Steger.

His research is primarily in the foundations of computer science and discrete mathematics. Specifically, he is interested in combinatorial algorithms, random graph processes, Ramsey theory, and combinatorial games. For more information about his research, please see his web page at

PhD positions at FoCS group (apply by March 31, 2019)

PhD positions are available in the Centre for Doctoral Training (CDT) at the Department of Computer Science, University of Warwick, UK.
The Theory and Foundations group in the department is inviting applications from those interested in theoretical computer science. The group works on various aspects of theoretical computer science such as:

  • algorithmic aspects of game theory and economics,
  • approximation algorithms,
  • automata and formal languages,
  • computational complexity,
  • cryptography and quantum computing,
  • discrete mathematics, combinatorics, and their applications,
