Research Interests

I am a statistician working with biological datasets to understand the mechanisms underlying human disease and identify possible treatments. Such work is only possible with close collaboration with biologists, and I moved to the CIMR in 2009 to pursue these collaborations. During the GWAS era, we, and others, identified many genetic polymorphisms that alter risk of human diseases such as type 1 diabetes and hypertension. My focus has now mostly shifted towards identifying the molecular function of these variants. I am particularly interested in disentangling apparently colocalising traits, to understand if the effect of a variant on disease is mediated by its effect on another trait such as gene expression or whether a common variant alters risk of two related diseases, and to developing new and powerful methods for examining allelic expression imbalance within individuals. Statistically, my current work is focused on variable selection, Bayesian model averaging and mixture models.
