After time as a postdoc and lecturer in the Maths department at the University Nottingham Gareth joined the Maths department at UEA. Eventually after a spell as Dean he moved to  CMP.

Key Research Interests

Gareth Janacek is part of the Knowledge Discovery and Data Mining Group

Gareth is a member of the Modeling and Algorithms Group [MAG] within the School of Computing Sciences at UEA and his main interests are:

The Analysis of time series:

He has had a long running interest in time series analysis, current interests include;

  • The clustering of time series, in particular using clipped series.
  • Spatial time series models, in particular for modeling the Madden Julian effect.
  • The analysis of extremes of UK temperature and rainfall time series.

Statistical Quality Control:

After spending much time as a guest of the Manufacturing Engineering Department at Warwick he got interested in problems in quality control, in particular SPC.

Statistical Modeling:

He has always had a passion for statistical modelling in almost all areas and is evangelical about the use of R for this purpose.
