Barry M. OConnor

Curator of Insects


Research Interests

Entomology, Systematics, Coevolution.

Dr. OConnor's major research interests are in the study of coevolutionary patterns among arthropods primarily mites, and other organisms. These studies entail the systematics of parasitic and commensal mites associated with vertebrates, insects, fungi, and other groups. Studies on ecological interactions within these systems are an integral part of coevolutionary research, with field studies supplementing laboratory investigations. Systematic research stresses phylogenetic analyses of groups participating in coevolving systems.

Dr. OConnor received the Ph.D. degree from Cornell University in 1981. He is a past president of the Acarological Society of America and has held adjunct academic appointments at Ohio State University, Catholic University of Nijmegen, The Netherlands, and the Instituto Politecnico Nacional in Mexico City.
