Denis Michez is professor at the University of Mons (Belgium). He is the head of the laboratory of Zoology where he is developing studies to globally understand wild bee diversity and conservation. His Ph-D field background is Systematics. He is now leading projects exploring how bee diversity evolved at population and upper taxonomic levels (species, families) considering fossils, molecular phylogenies, phylogeography and bee-plant chemical interactions. He is also developing research to better understand status and trends of European pollinators, focusing on global threats like climate change, pesticide, heavy metals and phtalates.
