Biodiversity loss is one of the most severe challenges faced by the earth system today, with habitat loss being one of its main drivers. Although many countries are committed to the conservation of biodiversity, most of the current conservation efforts relied heavily on alpha taxonomy and focused on the conservation of species diversity and population sizes; the importance of genetic diversity and other evolutionary considerations remain largely underappreciated. My research aims at incorporating evolutionary thinking into oyster reef conservation projects, with the objective of recreating habitats that are both functional and self-sustaining in the long run. I am also interested on studying the effect of oyster on the microbial community composition in marine sediments, with the hope of gaining mechanistic understanding on how oysters, as ecosystem engineers, shape the nutrient flux in coastal habitats.
