about me

I’m David Dotson, a data scientist at Clear Demand. Formerly an academic, I specialize in developing software tools for answering domain questions from data with greater ease and speed. I am a Pythonista, Linux nerd, and a loud-and-proud advocate for the use of open source software in science.

Until June 2017, I worked as a research software engineer for the Beckstein Lab in the Center for Biological Physics at Arizona State University. I am still (very) loosely affiliated with the lab and its efforts.
