Dr. Igor Carboni Oliveira joins the FoCS group and the department as a new Assistant Professor

Igor Carboni OliveiraThe FoCS group and the Department of Computer Science are welcoming our new Assistant Professor, Dr. Igor Carboni Oliveira, 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, Igor held postdoctoral positions at the Department of Computer Science at the University of Oxford and at the School of Mathematics at Charles University in Prague, and was a research fellow at UC Berkeley's Simons Institute for the Theory of Computing. He obtained his PhD in Computer Science from Columbia University in 2015. He is also Royal Society University Research Fellow 2019.


His research is primarily focused on the limitations of algorithms and computations, with connections to combinatorics and mathematical logic. For more information about his work and interests, please see his web page at https://www.dcs.warwick.ac.uk/~igorcarb/

EPSRC funding success for Dr Sayan Bhattacharya

Dr Sayan BhattacharyaWe are pleased to report that Dr Sayan Bhattacharya from the Theory and Foundations research theme at the Computer Science Department has received an EPSRC New Investigator Award. This will allow him to lead a research project on the theory and applications of dynamic algorithms. The approximately £250K project will aim to develop new techniques to design algorithms for fundamental optimisation problems in a setting where the input data changes over time.

The proposal was ranked top at its funding prioritisation panel, and the reviewers said:

The intended research explorations are of very high quality and will likely make a substantial impact on the research community; and possibly on the industrial sector.

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, https://algouk.wixsite.com/warwick2019.

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.

The Warwick AlgoUK workshop's web page is available at https://algouk.wixsite.com/warwick2019.
