Joe Hanson is a biologist, science writer, and the creator and host of PBS Digital Studios’ science education series It’s Okay To Be Smart, which takes a fun-loving look at the world of science through the lens of pop culture, history, and comedy. Before his days as a science communicator and journalist, he received a Ph.D. in cell and molecular biology from the University of Texas at Austin.

Joe’s writing has been featured in WIRED, Nautilus, The Open Laboratory, and Science Blogging: The Essential Guide. He once had a Twitter conversation with an astronaut while they were in space, which is pretty neat.
