Jonathan Grudin was a researcher at Microsoft from 1998 to 2022 and is affiliate professor at the University of Washington Information School working in the fields of human-computer interaction and computer-supported cooperative work. Grudin is a pioneer of the field of computer-supported cooperative work and one of its most prolific contributors. His collaboration distance to other researchers of human-computer interactions has been described by the "Grudin number". Grudin is also well known for the "Grudin Paradox" or "Grudin Problem", which states basically with respect to the design of collaborative software for organizational settings, "What may be in the managers' best interests may not be in the interests of individual contributors, and therefore not used." He was awarded the inaugural CSCW Lasting Impact Award in 2014 on the basis of this work. He has also written about the publication culture and history of human-computer interactions.
