I earned my BS & MA in Biology at Long Beach State (CA) working primarily on birds with a minor in Entomology. I earned my PhD at the University of New Mexico working on scorpions. I've lived in Southern California, North Florida, New Mexico, Sydney Australia and Ohio. I'm interested in birds and arthropods, particularly spiders and scorpions.

My latest project is a general-focus color illustrated guide to spiders of North America, north of Mexico: Common Spiders of North America. This guide is available through University of California press also Amazon. If you decide to purchase the electronic version, I would choose the Kindle format from Amazon. The links are much more functional and pinch-to-zoom works better. The e-version does suffer from not as sharp illustrations as the print version. This is NOT a comprehensive guide, but does have much broader coverage than anything else out there at the moment. It has 469 species included, but if you consider the "look alike" similar species in the genera included it "covers" about 2,800 species.
