### Biography

I hold the position of Senior Lecturer (Statistics) in the Department of Mathematics and Statistics and am co-PI (with Professors Stephen O'Brien, and Eugene Benilov) of the applied mathematics and statistics SFI funded research group MACSI (www.macsi.ie) I lead a work packages in the EI/IDA funded UL based Pharmaceutical Manufacturing Technology Centre (PMTC). I am also a Health Research Institute affiliated researcher.

### Research Interests

My main research area concerns the statistical analysis of curve data as applied to the area of human biomechanics. My main collaborators in this area are Doctors Drew Harrison (PESS) and Norma Bargary (MACSI). Our current research is concerned with developing mathematical and statistical models to help understand the relationship and interaction between biomechanical function and muscular stimulus. I also have considerable experience analysing large epidemiological / population based data sets and data from biomedical applications. Other research interests include multivariate general linear mixed models, outlier detection, functional data analysis.
