Overview

I am currently a Lecturer in the Section of Applied Statistics at the University of Reading.

My research interests centre around the application of statistics to problems in genetics. Ongoing research includes estimating population genetics parameters such as the inbreeding coefficient and formulae for relatedness testing. Collaborative research includes the analysis of data from prospective studies on shingles patients, evaluation of markers for species identification and analysis of bryozoan statoblast data.

Background

Jan. 2002 -
Lecturer, School & later Section of Applied Statistics, University of Reading.
  • 2003 - successfully completed the University of Reading Certificate in Further Professional Studies in Higher Education (accredited by the ILTHE)
  • 2005 - School Award for Teaching Excellence (Rising Star)
  • 2007 - School Award for Teaching Excellence

 
Aug. 1999 - Dec. 2001
Research fellow, Department of Applied Statistics, University of Reading.
The project (funded by the BBSRC) focused on the development of new statistical techniques (using coalescent methodology) for investigating DNA sequence variation on the human X chromosome (mutation and recombination rates). The project was supervised by David Balding and John Whittaker, and was in collaboration with Francesco Giannelli and colleagues at Guys Hospital, London, who generated data for the project.
 
Jan. 1999 - July 1999
Research assistant, Dept. of Environmental and Preventive Medicine, Wolfson Institute of Preventive Medicine, St. Bartholomew's and the Royal London School of Medicine and Dentistry.
Work included (i) analysing data from a prospective cohort study for haemostatic risk factors for heart disease (myocardial infarction) in middle-aged men (working with George Miller), and (ii) maintaining the computer database for the European Randomised Trial of Ovarian Cancer Screening (ERTOCS; working with Deborah Ashby); also web administrator for Wolfson Institute of Preventive Medicine.
 
1995 - 1998
Ph.D. in Applied Statistics at the University of Reading (first year completed at Queen Mary & Westfield College, London).
I was supervised by David Balding, and was funded by a studentship from the EPSRC. My thesis is entitled "Measuring Genetic Correlations Within and Between Loci, With Implications For Disequilibrium Mapping and Forensic Identification".
 
1994 - 1995
M.Sc. in Statistics at the London School of Economics.
 
1991 - 1994
B.Sc. in Pure Mathematics (1st class honours) at Queen Mary & Westfield College, University of London.
