I use this blog primarily to share nature photographs (my full collection is here). But most people come here for my tips on scientific posters. And, yes, I’m the guy who ate the 8 year-old Twinkie.

You can also find me on Twitter and Instagram.

In case you’re interested, I’m a graduate of Reed College (BA) and Brown University (PhD), then did post-doctoral research at Washington University and the University of Chicago. I taught evolutionary biology at Swarthmore College from 1997 to 2011. Prior to all the academic stuff I baked cakes for Denison University’s president (back when I was a teen). Yo Yo Ma said my lemon cake was delicious.

Random fun facts: I’ve been hit by lightning, stuck in quicksand, and tear-gassed. I was with my mom for two of these events.

If my posts have brought you happiness in some way and you’d like to buy me a virtual coffee, you can do that via my ko-fi page. Or surprise me with a book from my Amazon wishlist. For those wanting to help me even more, you can donate to my GoFundMe campaign (a pesticide company is suing me for alerting the EPA).
