October 2024: retreat

This year's retreat was a joint venture between PopGen and the SFB: Polygenic Adaptation. Twenty-eight students, postdocs, and faculty from five institutions met near beautiful Altaussee in the Alps for scientific talks, discussion, hiking, Austrian food, and great views. We're already excited for next year! Thank you Claus Vogl for most of these photos.

September 2024: Sturm Party

Continuing an annual tradition, Christian Schlötterer hosted PopGen students and faculty for a sturm party. Sturm is new wine, only partially fermented (very sweet and a little bubbly). Happy fall!

August 2024: Student fellowship

Major congratulations to PhD student Ioanna Kotari (Borges group), who earned a prestigious 2-year DOC fellowship from the ÖAW (Austrian Academy of Sciences) with her project "PoMo-cod: Integrating Demography and Selection in Codon evolution.

During this fellowship she will aim to advance evolutionary biology through the development of "PoMo-cod" (Polymorphism-aware phylogenetic Model for CODon evolution). Traditional models often overlook genetic variation within species and other key factors such as demographic changes and selection on synonymous sites. PoMo-cod addresses these gaps by incorporating polymorphisms, population size variations, and GC-bias gene conversion, providing a more comprehensive understanding of evolutionary processes.

Key goals of PoMo-cod include:

  • Explicitly modelling positive diversifying selection, which drives adaptation through recurrent amino acid changes.
  • Integrating varying demography, GC-bias gene conversion and selection pressures, including those on synonymous sites, for more accurate evolutionary inferences.
  • Detecting patterns of diversifying selection in fruit fly and great ape datasets, leveraging their diverse genomic attributes.

By utilising Bayesian and Maximum likelihood frameworks, along with exploring AI and Machine Learning to alleviate some computational burden, PoMo-cod aims to improve computational efficiency and accessibility, enabling more precise analysis of multi-individual and multi-species data. This will benefit the broader scientific community and advance the field of evolutionary research.

July 2024: Farewell Rui!

We were sad to say goodbye to Rui Borges, who has been at the Institute of Population Genetics at Vetmeduni since 2017, first as a postdoc and then as a group leader. But we are also excited for him about his new position as Lecturer in Statistics in the School of Mathematics and Statistics at University of St Andrews in Scotland. Congratulations and good luck with the move! His students will continue being affiliated with PopGen Vienna.
