In my research I use genomic data and methods to study classic evolutionary questions, often regarding the genetic causes and genomic consequences of plant mating system shifts. A population geneticist by training, I am especially interested in how selection affects different classes of sites across plant genomes. I am also very interested in the evolution of loci under balancing selection, and several of my past and ongoing project grants concern mating system supergenes and self-incompatibility loci.

I have worked extensively on the crucifer genus Capsella, but am now also conducting evolutionary genomic studies in a range of other systems, including wild Linum species. 

I received my PhD from Uppsala University in 2007 with Martin Lascoux as supervisor. As a post-doctoral fellow with Stephen Wright, I worked on inference of demographic history and mating system evolution. As an Assistant Professor at Uppsala University, I started my own group working on plant evolutionary genomics. In April 2014 I took up a position as Associate Senior Lecturer and SciLifeLab fellow at Stockholm University and SciLifeLab. I became docent in Ecological Genomics at Stockholm University in 2016, Associate Professor in 2018, and Professor in 2022.
