Research Description

My general interests include Bayesian and computational statistics, particularly when applied to problems in population genetics.  Specific interests include:

  • estimating haplotypes from population genotype data (for which I distribute a software package PHASE).
  • developing statistical models for patterns of linkage disequilibrium across multiple loci, and using these patterns to identify recombination hotspots.
  • spatial modelling of allele frequency variation.
