Dr. Johnson has served on the faculty since 1984 and was promoted to Full Professor in 1994. He was a co-founder of Privaris, a biometrics security company, and served as Chief Executive Officer from 2002 to 2006 while on leave from the University of Virginia. He served as the SEAS Senior Associate Dean from 2006 to 2015 and was also Associate Dean for Research from 2006 to 2011. He served at the National Science Foundation (NSF) from 2015 to 2019 as Director of the Division of Industrial Innovation and Partnerships. He has published two books, eight book chapters, and more than 150 technical articles. Dr. Johnson was named a Fellow of IEEE for his "contributions to fault-tolerant computing". He has also been elected to the National Academy of Inventors for "important innovations in computer system safety and security" based on the more than 40 issued patents on which he is an inventor.
