Tanja is a population geneticist who studies the genetic basis and genomic consequences of classic evolutionary transitions such as plant mating system shifts. She is broadly interested in using population genetic methods to understand how selection affects different classes of sites across plant genomes, and in the evolution of loci under balancing selection, such as mating system supergenes and self-incompatibility loci.

Tanja received her PhD from Uppsala University in 2007. As a post-doctoral fellow with Stephen Wright, she worked on the demographics of speciation and mating system evolution. As an Assistant Professor at Uppsala University, she started her own group working on plant evolutionary genomics. In April 2014 she took up a position as SciLifeLab Fellow at Stockholm University. In 2016 she became docent in Ecological Genomics at Stockholm University, in 2018 Associate Professor, and in 2022 Professor. Since 2021 she is also the subject representative for the PhD programme in Ecology and Evolution at the Dept. of Ecology, Environment and Plant Sciences, Stockholm University.

CV

Panagiotis-Ioannis Zervakis, PhD student

Panagiotis_brighter-2Panagiotis received his Master’s Degree in Evolutionary Biology from Uppsala University, where he completed a degree project on human population genomic analyses in the group of Prof. Mattias Jakobsson. Panagiotis started his PhD studies on January 18th, 2021, and is working on the evolution of the distyly supergene in Linum and population genomic analyses of plant mating system shifts.

Marco joined the lab in 2017, first as a postdoctoral fellow, and then transitioned to a position as researcher and bioinformatician. Marco did his PhD on genetic diversity and climate adaptation in Arabidopsis lyrata, at University of Neuchatel and University of Basel. In the Slotte lab he has worked on mating system evolution and population genomic analyses in the Brassicaceae, and currently he is working on bioinformatic analyses in the Linum distyly S-locus project.
