## Research interests

### Research Interests

My research interests are in developing new clustering and classification methods. Past work has involved research on finite mixture model based methods and variations that incorporate variable selection and semi-supervised updating. Currently I am working on creating hybrid clustering methods using both parametric and classical algorithmic approaches. I have also developed new mixture model clustering methods for discrete and space-restricted data. Social network analysis and dynamic treatment regimes are also current areas of interest. Application areas I have looked at include: housing markets, cDNA microarrays, electronic educational testing, food authenticity studies and many others. I am on the committee for an International Federation of Classification Societies initiative to promote good benchmarking practices in clustering research.
