Welcome to the website of the Statistical Genetics Group! The group is part of the Division of Biostatistics at the Institute of Social and Preventive Medicine of the Lausanne University Hospital and affiliated with the Swiss Institute of Bioinformatics. We are interested in the development of statistical methodologies in order to decipher the genetic architecture of complex human traits. Although our main focus is Genome-Wide Association Studies, we devise integrative analysis tools for different omics data to enhance our understanding of the genetic network of the human genome.

Furthermore, we are heavily involved in the activities of the GIANT consortium (http://www.broadinstitute.org/collaboration/giant/index.php/GIANT_consortium) and in various genetic analyses of

  • the Cohorte Lausannoise (CoLaus) study
  • the Swiss Hepatitis C Cohort Study (SCCS)
  • the Swiss Transplant Cohort Study (STCS)
  • the European Narcolepsy Network (ENN)
  • the Hypergenes study
