Christopher B. Cameron. Université de Montréal, Département de sciences biologiques, C.P. 6128, Succ. Centre-ville, Montréal, QC, H3C 3J7, Canada. c.cameron@umontreal.ca
Christopher Cameron is a full professor in the département des sciences biologiques, Université de Montréal. His academic focus and expertise lie primarily in the origins and evolution of animal body plans, with a significant publication record in the comparative morphology and development, phylogenetics, fluid mechanics and palaeontology of marine invertebrates. He holds an NSERC Discovery grant that supports his research on extracellular matrix structures, including the gill bars, tubes, and skeletons of hemichordates, echinoderms and chordates. He has been at the Université de Montréal since 2006 and has supervised a substantial number of post-doctoral fellows, graduate students, and undergraduate students. In Québec, he works to braid indigenous knowledge with western science as a contributor to the annual Indigenous Science Fair.
