Prof Dan Bradley - Speaker Profile

Name - Professor Daniel Bradley
              Professor of Genetics, TCD

  • Member of International Society of Animal Genetics 
  • Member of the Royal Irish Academy
  • Five times juror in the European Contest for Young Scientists 
  • Fellow of Trinity College Dublin

Position - Dan holds a Personal Chair in the Smurfit Institute of Genetics, Trinity College Dublin, and has written or co-authored over 110 publications including many in premier journals (e.g. Science, PNAS, Nature) – see Publications below.

Involvement with genetic genealogy?
Dan has researched in the following areas: 
  • Y chromosome diversity, Irish medeival genealogies, and the genetic architecture of Irish surnames
  • Irish human population structure
  • Ancient DNA
  • Detection of signatures of selection in human, bovine, salmon and chicken genomes
  • Origins of livestock as discerned using genetic diversity
  • Genetic basis of disease resistance in cattle

So what will be the topic of the presentation at GGI2016?
Many ancient Irish skeletons are currently undergoing ancient DNA analysis. They vary in age and some are up to 6000 years old. This year saw the publication of the first of several papers reporting on the analysis of four such skeletons which were found in Rathlin Island and Ballynahatty. Further research is ongoing and Dan will give us an update on this and what to expect in the near future.

What DNA tests will be discussed?
Primarily Y-DNA
