## Research

**Research Area:** Computational Statistics**Research Profile: **Dr. McNicholasâ€™ research focuses on computational statistics, and he is at the cutting edge of international research on mixture model-based clustering and classification. Current research includes work on big data featuring outlying or spurious points, with a focus on classification, clustering, dimension reduction and discriminant analysis. Another important aspect of Dr. McNicholasâ€™ current research is work on non-Gaussian mixture models, which present a useful alternative to the Gaussian mixture model. Work on clustering categorical data and data of mixed type is ongoing. Applications of Dr. McNicholasâ€™ research are readily found in several fields, including bioinformatics, sensometrics, and psychometrics.
