David Demory is a multidisciplinary quantitative microbial aquatic ecologist coupling theoretical-, experimental-, and field-based approaches. He received his Bachelor of Science in aquatic sciences and mathematical ecology from the Mediterranean Institute of Oceanography (University Aix-Marseille II, France). He continued with a master’s degree in oceanography, modeling and data analysis from the Institute of Marine Science of Rimouski (University of Quebec at Rimouski, Canada) and the Mediterranean Institute of Oceanography (University Aix-Marseille II, France). He received his Ph.D. in 2017 from the University of Pierre and Marie Curie (UPMC, University Paris 6, France) in collaboration with three French laboratories: the Laboratory of Oceanography of Villefranche-sur-Mer (CNRS, UMR7093), The Biological Station of Roscoff (CNRS, UMR7144), and the BIOCORE team at INRIA Sophia Antipolis where he explored the impacts of temperature on phytoplankton and virus dynamics. He joined the Weitz group in 2017 to develop ecological models of virus-phytoplankton dynamics in aquatic systems. David never likes to be far away from the sea or the mountains, and enjoys being in nature, hiking, and climbing. He loves music and plays jazz and Gypsy guitar during rainy days. Recently, he bores people trying to learn Tin whistle.
