We study diverse topics in evolutionary genetics, but focus on the evolution of populations that are distributed through space, and that experience natural selection on many genes.  Understanding how species adapt, and how they split into new species, requires knowledge of the effects of spatial subdivision; conversely, spatial patterns can tell us about the strengths of evolutionary processes that are hard to measure directly.  Interactions between large numbers of genes are important in species formation, in the response to natural and artificial selection, and in the net effects of selection on the whole genome.  The recent  development of techniques for assaying large numbers of genetic markers, and indeed complete sequences, make analysis of the interactions amongst large numbers of genes essential.

  • January 30th: Patricia Wittkopp visited IST Austria and the Barton group today. Besides giving a colloquium talk, she had fruitful discussions with various group members. A central theme was the current understanding of the evolution of gene regulation.
  • January 26th: Another passed qualifying exam! Stefanie Belohlavy took this important step towards her PhD by successully presenting her plans to a committee consisting of Reinhard Bürger and Nick. Her work will focus on Quantitative Genetics, in particular how the Infinitesimal Model relates to sequence data from artificial selection experiments. Congratulations!

  • January 25th: Rok Grah, a PhD student shared between the Barton, Guet and Tkacik group, successfully passed his qualifying exam. Congratulations!
  • Many members of the lab attended PopGroup50 in Cambridge. Nick Barton, Stefanie Belohlavy, Harald Ringbauer, Himani Sacheva, Barbora Trubenova gave talks about their recent work; Maria Clara Melo and Eniko Szep had poster presentations.
