I am broadly interested in the intersections of behavior, ecology, and evolution. Taxonomically, I am most passionate about herptiles, arthropods, and fungi (i.e., the slimy yet satisfying parts of organismal biology). Check out some of my ongoing research projects!

Just some guy with an appetite for nature, among other things.

I'm James, a broadly-trained biologist with special interest in natural history – what may be considered in scientific modernity an amalgamation of biology's triple E's (ecology, ethology, and evolution). I occasionally have an idea worth turning into a research project or writing about, without fail materializing while I am knee-deep in another project or seconds from sleep. But alas, I am not yet paid for these armchair duties, so I am resigned to fantasize and travail for those with more work ethic.

Some principles I [strive to] live by:

  • music is good
  • be nice to everyone, and be nicer if they're different than you
  • stop making/contributing to so much damn pollution
  • some products may be cheap, but the animal and environmental harms caused by them are not
