I went to school to become a molecular biologist. At some point in this long education, I discovered that I love communicating science to the general public: talks, writing, at a pub, on the street corner... Whatever venue will let me hold your attention for a few moments. Unfortunately, I can't do this for a living, since no one will pay me. So, I have a job as a molecular biologist at the University of Washington, where I get to work with great scientists on some really awesome projects, and I'll blog about science here at Muller's Ratchet in my spare time.
Why should the general public want to know anything about science? Here's my explanation (which also explains why I chose the name Muller's Ratchet for this site).
Briefly as a graduate student (before I had to devote all of my time to graduating), I blogged at Adaptive Radiation.
