Dr. Tanja Slotte, Associate Professor in Ecological Genomics

TS_portrait2 (1 of 1)

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 (see CV).

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 and in 2018 she became Associate Professor in Ecological Genomics.

Dr. Benjamin Laenen, Postdoctoral researcher

Benjamin_LaenenBenjamin is a postdoctoral researcher who joined the lab in February 2015. Ben is particularly interested in impact of life history traits, such as mating systems or dispersal capabilities, on species diversification. He has also studied the impact of glacial periods on population structure of bryophytes, a group of early haploid land plants, including the role of oceanic islands in the post-glacial recolonisation of Europe. During his PhD studies at University of Liege in Belgium, he worked on the “Liverwort Tree of Life” project (Duke University). He is currently working on the causes and population genomic consequences of mating system shifts in the Brassicaceae.

Selected Publications

Dr. Marco Fracassetti, Postdoctoral fellow


Marco is a postdoctoral fellow who joined the lab in 2017. Marco did his PhD on genetic diversity and climate adaptation in Arabidopsis lyrata, at University of Neuchatel and University of Basel. He is currently working on mating system evolution and population genomic analyses in the Brassicaceae.


Dr. P. William Hughes, Postdoctoral fellow

William Hughes

William is a postdoctoral researcher who joined the lab in November 2018. William’s main interests are on the evolution of reproductive traits that shape life history strategies. During his postdoctoral work at the Max Planck Institute for Plant Breeding Research, William studied the evolutionary consequences of pleiotropic regulation of flowering and seed traits in the Brassicaceae. William completed his PhD at Carleton University, where he studied phenotypically plastic semelparity in the herbaceous monocarp Lobelia inflata (Campanulaceae). He is currently working on the Linum distyly S-locus project.

Dr. Aurélie Désamoré, Research Engineer/Lab manager


Aurélie is working as a research engineer/lab manager for the Slotte lab since April 2017. She mainly worked in evolutionary biology and phylogeography in a range of organisms including tree heath (Ericaceae), endemic halophytes (Limonium), mosses, liverworts, diving beetles and is interested in macro-evolution and population genetics. She has postdoctoral experience from the Botanical Garden in Zurich and the Natural History Museum of Stockholm.
