Dr. OConnor's major research interests are in the study of historical, ecological, and 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 his Ph.D. degree from Cornell University in 1981. He is past president of the Acarological Society of America. He has ongoing field research studies in Central America and East Africa as well as in the United States. OConnor, B.M. 1993. Life history modifications in astigmatid mites .
