Education
Crowcroft's father was the psychiatrist Andrew Crowcroft and his mother the concert pianist Kyla Greenbaum.{{Cite news|url=http://www.theguardian.com/news/2002/mar/22/guardianobituaries.medicalscience|title=Obituary: Andrew Crowcroft|date=22 March 2002|newspaper=The Guardian|access-date=7 August 2020}} He was educated at Westminster School{{Official URL}} and graduated with a Bachelor of Arts degree in physics in 1979 from the University of Cambridge where he was an undergraduate student of Trinity College. He then gained a Master of Science degree in computing in 1981 and PhD in 1993,{{cite thesis|degree=PhD|publisher=University of London|url=https://discovery.ucl.ac.uk/id/eprint/10102875/|title=Lightweight protocols for distributed systems|first= Jonathan Andrew|last=Crowcroft|date=1993|id={{EThOS|uk.bl.ethos.812029}}|website=ucl.ac.uk|oclc=940339238}} {{open access}} both from University College London.
Career and research
Crowcroft joined the University of Cambridge in 2001, prior to which he was Professor of Networked Systems at University College London in the Computer Science Department. After he stepped down from UCL, he was succeeded by his former PhD student Mark Handley. {{As of|2020}} he is a Fellow of Wolfson College, Cambridge.
Crowcroft contributed to successful start-up projects.{{clarify|date=November 2020}} He has been a member of the Scientific Council of IMDEA Networks Institute since 2007. He served on the advisory board of Max Planck Institute for Software Systems .
Crowcroft has written, edited and co-authored books and publications which have been adopted internationally in academic courses, including TCP/IP & Linux Protocol Implementation: Systems Code for the Linux Internet,{{cite book |author1=Phillips, Iain |author2=Crowcroft, Jon |title=TCP/IP and Linux protocol implementation: systems code for the Linux Internet |publisher=Wiley |location=New York |year=2002 |isbn=978-0-471-40882-6 }} Internetworking Multimedia{{cite book |author1=Wakeman, Ian |author2=Crowcroft, Jon |author3=Handley, Mark |title=Internetworking multimedia |publisher=Taylor & Francis |location=Washington, DC |year=1999 |isbn=978-0-7484-0808-5 }} and Open Distributed Systems.{{cite book |author=Crowcroft, Jon |title=Open distributed systems |publisher=Artech House |location=Boston |year=1995 |isbn=978-0-89006-839-7 }}
Crowcroft has also done research in theoretical network science, particularly in the area of Turing switches, and he has suggested to replace general-purpose computers acting as network switches with specially-built hardware dedicated to packet switching, as well as using optical technology for the same purpose.Jon Crowcroft [http://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-556.pdf Turing Switches. Turing machines for all-optical Internet routing] UCAM-CL-TR-556 ISSN 1476-2986 January 2003
