# Peter G. Harrison

**Peter George Harrison** (born 1951) is a Professor of Computing Science at Imperial College London[3] known for the reversed compound agent theorem, which gives conditions for a stochastic network to have a product-form solution.

Harrison attended Christ's College, Cambridge, where he was a Wrangler in Mathematics (1972) and gained a Distinction in Part III of the Mathematical Tripos (1973), winning the Mayhew Prize for Applied Mathematics.[4]

After spending two years in industry, Harrison moved to Imperial College, London where he has worked since, obtaining his Ph.D. in Computing Science in 1979 with a thesis titled "Representative queueing network models of computer systems in terms of time delay probability distributions" and lecturing since 1983.[5]

Current research interests include parallel algorithms, performance engineering, queueing theory, stochastic models and stochastic process algebra, particularly the application of RCAT to find product-form solutions.[6]

Harrison has coauthored two books, *Functional Programming* with Tony Field,[7] and *Performance Modelling of Communication Networks and Computer Architectures* with Naresh Patel[8] and published over 150 papers.[9]

Harrison is an associate editor of The Computer Journal.[10]

Via Saharon Shelah and Dov Gabbay, Harrison has an Erdős number of 3.[11]
