My research interests lie in field of conservation genomics and avian evolution. I am particularly interested in the genome-wide effects of population declines and fragmentation on population persistence. I am also interested in the consequences of translocations on population fitness.
My current research focuses on the genome-wide consequences of population declines in extinct and critically endangered species. My aim is to quantify changes in heterozygosity and inbreeding as well as the accumulation of deleterious mutations by examining genomes collected before and after population decline. This approach will allow me to understand the role that genetic factors can play in population decline and eventually extinction.
This project is particularly relevant in the context of the current human-induced sixth mass extinction where it has become critical to understand genetic consequences of population declines if we want to develop effective conservation guidelines for endangered species. Moreover, we will participate in the development of palaeogenomics as a promising tool for conservation.
