Jeff is a systematist \u2013 a scientist who focuses on studying the evolutionary relationships and taxonomy of living things. He works mostly on higher flies and has conducted most of his research on big-headed flies (Pipunculidae), thick-headed flies (Conopidae) and flower flies (Syrphidae). Graduate students have worked with Jeff on all of these fly families as well as a few other groups. Much of the current work in his lab are on flower flies. Cutting edge phylogenomic techniques are used to generate large datasets for phylogenetic analysis and taxonomic projects rely heavily on the Canadian National Collection of Insects, Arachnids and Nematodes (CNC is the 5th<\/sup> largest collection of arthropods in the world with over 17 million pinned specimens). Over 18 scientists work on systematics of arthropods at the CNC, making it the largest and most dynamic group of systematists under one roof anywhere in the world.<\/p>\n Beatty, C. D., Herrera, M.
