Kate lives in Silicon Valley, comfortably close to Apple. She received her PhD in Computational Linguistics from Georgetown University. Circumstances and her interests have taken her from artificial intelligence, to speech recognition, to course development, to prototyping GUIs—back in the day—to usability evaluations. She published several papers and edited one book, Video-Mediated Communication, before leaving the world of corporate research to raise a family in 1995. For many years, she worked as a freelance usability specialist. Then, in 2011, she and Jeff Johnson formed Wiser Usability to focus on age-friendly design.
