Professor Xiaohui Liu (PhD, CEng, FBCS)
College of Engineering, Design and Physical Sciences
I joined Brunel as Professor of Computing in 2000. Prior to that, I was a member of academic staff at Birkbeck, University of London in Computer Science and research staff at Durham and Heriot-Watt Universities in Engineering. At Brunel, I was Director of Research for the School of Information Systems, Computing and Mathematics (2006-2014) and Doctoral Programme Director for Computer Science (2008-2013).
My research interests include the construction of computationally intelligent algorithms, software and systems as well as the integration, analysis and visualisation of large-scale, fast evolving real-world complex data. I chaired the first (see the conference report) & second International Symposia on Intelligent Data Analysis in 1995 & 1997. More recently, I have been calling for the introduction of a new A-level course in the UK on Data Analytics to lay a firm foundation for next generation data scientists in light of Big Data (see an official report: A World Full of Data by Roger Porkess, launched by the Royal Statistical Society and the Institute and Faculty of Actuaries on 11 September 2013).
I have advised funding agencies on interdisciplinary research programmes in data analytics, genomics and security as well as served on grant panels of research councils in the UK, including the BBSRC, EPSRC and NERC. Recently I have been named as a 2016 Web of Science Highly Cited Researcher (HCR). Previously I was also included in the list of Thomson Reuters HCRs in 2014 and in 2015.
News: Miqing Li, a PhD student at the Centre for Intelligent Data Analysis, was announced as the winner of the Best Student Paper award at the IEEE Congress on Evolutionary Computation (CEC-2014) for the paper entitled “A Test Problem for Visual Investigation of High-Dimensional Multi-Objective Search”.
