Liam Steadman


I am a postgraduate research student within the CDT in Urban Science and Progress at the University of Warwick. I graduated with an MEng degree in Computer Science in 2016 and am now under the supervision of Prof. Nathan Griffiths and Prof. Stephen Jarvis.


My primary research area is spatiotemporal data processing, particularly within the transportation domain. I am interested in how we can permit analysis and modelling of spatiotemporal datasets when the volume of data rules traditional techniques impractical. My research includes:

  • Spatiotemporal Data Reduction 
    Data generated by sensors in the environment, such as traffic count data, is growing in volume at increasing rates. Analysing and processing this data in a timely manner is therefore becoming impractical using traditional techniques. My work investigates how we can reduce a dataset's volume, using summaritive models that sacrifice spatial or temporal resolution when possible, without losing meaningful information.
  • Spatiotemporal Data Linking
    Often datasets become more meaningful when they are analysed in the context of other datasets. However, the volume of these joined datasets can become too great for later analysis or processing. Therefore, I am investigating methods for linking spatiotemporal datasets after they have been reduced to enable learning from the linked data.

The data I work with is primarily sourced from the transportation domain. My research is supported by the Transport Research Laboratory.

For the 2018/19 academic year I have been involved with the teaching of the following modules:

Previously I have assisted with the following modules:

  • CS140 Computer Security
  • CS241 Operating Systems & Networks
  • CS261 Software Engineering (group software project)
  • CS352 Project Management for Computer Scientists

WISC CDT Student-Staff Liaison Committee

This year I am fortunate to have been awarded 'SSLC Chair of the Year' by Warwick Students' Union for my work as chair of the WISC CDT Student-Staff Liaison Committee. If you have any concerns, queries or suggestions and sit within the CDT, please feel free to email me or talk to your other student representatives.
