BiographyHowdy! I'm Alexander R. Toftness (he/him) and I earned my Ph.D. in cognitive psychology at Iowa State University. Much of my research focuses on educational psychology and neuropsychology. I usually go by Xander, and I have been a science communicator since 2014. In that time I have made around a hundred educational videos, presented science both to the general public and at academic conferences, and written many articles both for a lay audience and peer-reviewed publications. I specialize in science writing and video editing, but I also know my way around creative writing. When not writing or editing video, I am usually reading a book with my cat, Sabrina. In 2022, I published a multimedia video/book project with Routledge that explains types of brain damage in simple terms. It's called "Incredible Consequences of Brain Injury: The Ways Your Brain Can Break." My wife and I live in Iowa where we teach psychology courses.
