Peter William O'Hearn FRS FREng[7][13] (born 13 July 1963 in Halifax, Nova Scotia) is a Research Scientist at Facebook[14] and a Professor of Computer science at University College London (UCL).[15] He has made significant contributions to formal methods for program correctness. In recent years these advances have been employed in developing industrial software tools that conduct automated analysis of large industrial codebases.[10]

Education

Peter O'Hearn attained a BSc degree in Computer Science from Dalhousie University, Halifax, Nova Scotia (1985), followed by MSc (1987) and PhD (1991) degrees from Queen's University, Kingston, Ontario, Canada. His dissertation was on Semantics of Non-interference: A natural approach, supervised by Robert D. Tennent.[11][16]

Career and research

O'Hearn is best known for separation logic,[2] a theory he developed with John C. Reynolds that unearthed new domains for scaling logical reasoning about code. This built upon previous research from O'Hearn and David Pym on logic for resources — Bunched logic.[3]

Separation logic has given rise to the Infer Static Analyzer (Facebook Infer), a static program analysis utility developed by O'Hearn's team at Facebook.[4] After 20 plus years in academia, O'Hearn landed at Facebook in 2013 with the acquisition of Monoidics Ltd, a startup he cofounded.[17] Since its inception, Infer has enabled Facebook engineers to resolve tens of thousands of bugs before reaching production.[18] It was open sourced in 2016, and is used by Amazon Inc, Spotify, Mozilla, Uber, and others.[4]

O'Hearn was an Assistant Professor at Syracuse University, New York, United States, from 1990 to 1995. He was a Reader in Computer Science at Queen Mary University of London from 1996 to 1999 and then a full professor at Queen Mary until his move to University College London. He has been the recipient of a Royal Society Wolfson Research Merit Award,[7] a Most Influential POPL Paper Award,[19][20] and a Royal Academy of Engineering/Microsoft Research Chair[21] In 1997 he was a Visiting Scientist at Carnegie Mellon University and in 2006 he was a Visiting Researcher at Microsoft Research Cambridge.[16]

Awards and honours

With Stephen Brookes, Carnegie Mellon University, O'Hearn was co-recipient of the 2016 Gödel Prize, for the invention of Concurrent Separation Logic.[8] Also in 2016, he was elected Fellow of the Royal Academy of Engineering (FREng).[22] In 2018, he was elected Fellow of the Royal Society (FRS), and received an Honorary Doctor of Laws from Dalhousie University.[23][7][24]
