I've been interested in insects for as long as I can remember, and, judging by the picture at right, for longer than I can remember.
While my passion is for the genus Bembidion and its relatives, I am also interested in beetle diversity as a whole.
- Phylogeny of all beetles: The Beetle Tree of Life (BTOL), an NSF ATOL project, joint with Brian Farrell, Mike Whiting, and many others.
- Relationships of carabid tribes using molecular and morphological data (with Kip Will, Michael Baker, Karen Ober, Wendy Moore, Tana Ellis, Jim Liebherr, David Kavanaugh, and Erik Arndt). For a list of beetle species I wish to acquire for this work, please see this list.
- Relationships of adephagan families (with Michael Baker, Karen Ober, Wendy Moore, et al.)
- Relationships of the carabid supertribe Nebriitae (with David Kavanaugh, Michael Baker, Karen Ober, Tana Ellis).
- Phylogeny of the carabid supertribe Trechitae
- The carabid genus Bembidion
- Systematics of subgenus Pseudoperyphus
- Systematics of subgenus Ochthedromus
- Systematics of subgenus Liocosmius
- Phylogeny of Bembidion
- Larval diversity
