Ph.D.,Plant Pathology from the Ohio State University. I study root-knot nematodes, and I have a keen interest in galling organisms of all sorts. Adjunct Instructor - College of Wooster, Post. Doc - Maize Lethal Necrosis, Redinbaugh Lab, Ohio State University.

Recommended Gall Identification Resources for the eastern United States
Getting started
- N. Charney and C. Eiseman - Tracks & Sign of Insects and Other Invertebrates: A Guide to North American Species - Has a good section covering most of the significant galling species. (2010)
- Cranshaw and Shetlar - Garden Insects of North America (2004) - Also a good place to look for general categories.

More advanced;
- E.P. Felt - Galls and Gall Makers (1940)- An oldie but a goodie
- L. H. Weld - Cynipid Galls of the Eastern United States (1959) - Great guide for the gall wasps
- R.J. Gagne - Plant-feeding Gall Midges of North America (1989) - Great for the midges
- R.J. Gagne - The Gall Midges (Diptera: Cecidomyiidae) of Hickories (Juglandaceae: Carya). (2008) - Caryomyia species treated in depth.
- R.J. Gagne - The North American gall midges (Diptera: Cecidomyiidae) of hackberries (Cannabaceae: Celtis spp.). (2013) - Celticecis species treated in depth
-T Pergande - North American Phylloxerinae Affecting Hicoria (Carya) & Other Trees (1909) - A good starting point for the hickory phylloxera, still learning these.
- Beutenmüller - North American species of Diastrophus and their galls (1909)
