As Curator of the Invertebrate Collection, Jean-Marc has been involved in collections management at the Canadian Museum of Nature for over 26 years. This work involves interacting with the people who use the collections such as scientists from other museums, universities and government departments, and also the general public looking for information on specific species.

The museum's Invertebrate Collection contains more than a million dry specimens (insects, shells, crustaceans, echinoderms, sponges, etc.), and nearly half a million jarred samples preserved in ethanol or formaldehyde.

In addition to curating the Invertebrate Collection at the museum, Jean-Marc builds on his background in marine ecology and studies the biology and distribution of deep-water species such as the giant file clam, and the differences between distant populations of lady crabs along the Northwest Atlantic Coast.

Jean-Marc was on the Executive Committee of the Society for the Preservation of Natural History Collections (www.spnhc.org).
