• My paper with Doug Speed has now appeared in Nature Genetics (advance online May 22, doi: 10.1038/ng.3865 preprint: BioRxiv).  We show that many existing results on SNP-heritability need to be re-evaluated with better models for effects of MAF, LD and genotype certainty.  Current estimates are generally too low because these factors are not modelled appropriately, but we also show that published estimates of heritability of DHS sites are far too high.  Two weeks out from publication it is still ranked no 2 under "most read" on the Nat Genet website.
  • My primary affiliation is the University of Melbourne, where since Nov 2014 I have  been joint between BioSciences and Maths & Stats (location details below).
  • I retain an affiliation with UCL.
  • Together with Debbie Kennett, Mark Thomas and Adrian Timpson, I have developed a set of web pages under the heading "Debunking Genetic Astrology", aimed at highlighting misuses of genetic ancestry testing.  See
