I am a Scientist at WSL, specialising in conservation biology, population genetics / genomics, and bioinformatics. My interests focus on using genetic tools to support threatened species and support conservation management. Prior to working at WSL, I contributed to the IPBES's assessment of the status of biodiversity and assessed the proportion of genetic variation lost in the last century from wild species. I also have considerable interest in the budding field of macrogenetics. I also have extensive experience working on the genetics of reintroduced populations and captive breeding programs. I am a memeber of the IUCN SSC Conservation Genetics Specialist Group, GeoBON "Genetic composition working group, and the USGS Powell Centre Macrogenetics Working Group.
I am currently working on white oak species. This project is using genomic tools and experiments to study adaptation to drought across three species ( Quercus robur, Q. pubescens , and Q. petraea ) and is part of the ACORN collaboration with Christian Rellstab (https://www.acorn-biodiversa.net/) .
I previously worked in WSL's Phytopathology group and used genomic tools to characterize the intra-host diversity of the CHV-1 virus.
