Edit ProfileCareer
After moving to Calgary he began to work more generally with partially ordered sets, and to study fixed point theorems for partially ordered structures. He was a frequent organizer of conferences in order theory, and in 1984 he founded the journal Order. As a computer scientist at Ottawa, he shifted research topics, applying his expertise in order theory to the study of data structures, computational geometry, and graph drawing.
Rival grew up in Hamilton, Ontario.
He earned a bachelor"s degree at McMaster University in 1969, and received his Doctor of Philosophy from the University of Manitoba in 1974 under the supervision of George Gratzer. After postdoctoral stints visiting Robert Dilworth at Caltech and Rudolf Wille at the Technische Hochschule Darmstadt, he took a faculty position at Calgary in 1975, and was promoted to full professor in 1981.
In 1986, he moved to the University of Ottawa, where he became chair of the computer science department.
