Research Interests

Statistical genetics; genetic epidemiology

Research Activities

I work on both applied and theoretical problems in the study of complex disease genetics. Examples include:

  • studying the genetics of rolandic epilepsy
  • genetic modifiers in cystic fibrosis
  • applications of evidential statistics in genetics
  • development of evidential methodology for analysis of genetic data
