Christopher Alan Cockerill, PhD candidate in Ecology at Stockholm University. I have a Bachelors degree in Biology from Manchester Metropolitan University, class of 2019, and a Master's degree in Evolutionary Biology from Uppsala University, class of 2022. I have conducted the fieldwork and monitoring of the Swedish arctic fox population for 5 years with the Swedish Arctic Fox Project with Stockholm University. I recently finished my 60 hp Master's thesis within the project investigating the genomic consequences of fragmentation in the Fennoscandian arctic fox population. Following this, I completed a 10-week internship at the Centre for Palaeogenetics in Stockholm, where I extracted ancient DNA from late-Pleistocene Ptarmigans and prepared libraries for whole-genome sequencing. My current interest lies in the evolutionary history and genomic divergence of arctic foxes, specifically the arctic fox as a model species to investigate genomic signatures of past and present selective processes.
