Laura Bertola, Member

PhD Biology, Leiden. “I’m interested in how the rapidly developing field of genetics can contribute to the field of conservation biology. During my PhD I applied various techniques to gain insight into the distribution of genetic diversity in the lion. These data provide a rational basis for prioritising populations for conservation efforts, but also give insight into evolutionary drivers which may have contributed to the current genetic make-up. Phylogeographic data can contribute to defining management strategies, both for in situ conservation and for breeding of captive stocks. Currently, I’m working on a new research line on metagenomics, with potential applications ranging from water quality monitoring to diet analysis.”
