I have been the Insect Division Collection Manager at the UMMZ since 1981. I'm responsible for collection maintenance, curation, specimen preparation, loans, exchanges and Insect Division data resources. I have over 30 years of experience as an entomologist, and have worked on the biology of various sand wasps, forest entomology, and more recently, dragonflies. My expertise has been in the area of insect natural history, and the biology and distribution of Hymenoptera and Odonata in Michigan. My interest continues in the documentation of adventive species in Michigan, especially Hymenoptera.

In the area of Bioinformatics, I have participated in several iDigBio workshops, and have presented on topics of specimen imaging and digital archiving of collection-related materials.

I have served on several Michigan DNR committees to review threatened and endangered species. I have been a member of the Michigan Entomological Society since 1981, served as president twice, and was editor of the Great Lakes Entomologist for 10 years. I currently serve as the MES wbmaster.

I also coordinate the Michigan Odonata Survey. The MOS has been in existence since 1997, and with over 27,000 database records, thousands of new locality records, over 10 species added to the state list, and hundreds of hours of fieldwork, the time has come for the definitive catalog of Michigan Odonata. It is coming along slowly, but Julie Craves and I are collaborating on the Michigan Odonata Atlas, which we hope to have finished by early 2014. You can check on our progress here: Michigan Odonata Atlas

Michigan Odonotes is the blog I maintain on my activities with Michigan Odonata and anything related that's happening at the UMMZ.

When I'm not being an entomologist, I am a photographer, and have been exhibited in 12 shows since 2007. You can see more of my photography on Flickr. My photography blog might interest you too. I was also a board member of the Michigan Photographic Historical Society for 5 years.
