Evolutionary biology of sex differences

I have a broad interest in understanding how sexual and natural selection shape sex differences and what are their genetic underpinnings. I am just starting my own lab to study how sexual dimorphism evolves when the sexes are constrained by a genetic correlation due to the largely shared genome. My group will address this fundamental and long-standing question by investigating what kinds of genetic changes are required and how the fitness landscapes change for each sex in the process of divergent evolution between the sexes.

My ongoing work also involves various exciting collaborations to study life-history evolution in the sexes, both at the phenotypic level across phylogeny and at the genomic and transcriptomic levels. I am also studying the role of mitochondrial genetic variation in thermal adaptation and its consequences on reproductive fitness in the sexes.

In my previous work as a post-doctoral researcher in Göran Arnqvist lab  I have studied the role of mitochondrial and nuclear genome epistatic interaction in sex-specific life-history and reproductive traits, how mating influences sexual dimorphism in gene expression, the cost of reproduction at both mechanistic and fitness levels, and how the genetic architecture shapes these costs and affects ageing in each sex, using seed beetles as a model system.

In my PhD work I focused on the genetics of reproductive traits involved in species recognition as well as transcriptome evolution under sexual selection (in the Mike Ritchie lab), and the evolution of nuptial feeding (MSc) using Drosophila.
