I'm a biology major at Wheaton College near Chicago, focusing on ecology and evolutionary biology. At home I'm a curatorial assistant for the Santa Barbara Museum of Natural History. I specialize in Californian mollusks, but I'm also familiar with mollusks from other regions that I've explored. I love helping out with IDs, so feel free to mention me in any observations. Just know that when I'm away from home I only have my digital library, the internet, and whatever I can remember off the top of my head. As for my own observations, please let me know if I can take better photos! At school I am conducting research on the colonial hydroid Cordylophora. In general, I am fascinated by the diversity of life we are blessed with and I love getting outside and exploring it. Additionally, I love exploring the nuance of taxonomy. I also play classical piano and run cross country and track, specializing in the 800 m; my runs simultaneously function as casual birding excursions.

I have identified (or reviewed where appropriate) all of the following observations:
Banana slugs (see this post)
Lancetooth snails
West Coast Bivalves (Alaska through Baja California)
Santa Barbara County Mollusks (see this site for some terrestrial mollusks)
South Dakota Mollusks

I am currently working on identifying:
West Coast Bivalve Siphons (see this awesome project)

Groups I'd like to identify in the future (in order of importance):
Caribbean Cyphoma
Thailand mollusks
Northeastern Pacific dove snails
Northeastern Pacific Ocenebrinae
Northeastern Pacific Olivellinae

Here's some publicly available sources that I've found useful for mollusk IDs. Let me know if any of the links are broken or if you'd like anything more specific (there's lots more!).
