Hey, I’m Dr. Sparks. I write stories for people on a mechanical typewriter, and I want to use this storytelling as a way to teach kids STEM (science, technology, engineering, and mathematics) concepts. When I’m not typing, I’m Karl J. P. Smith, a scientist and storyteller with a Ph. D. in Biophysics from the University of Rochester. My science journalism has appeared in Scientific American, and I currently work as a software developer for Amazon’s Alexa voice assistant.
