The Ontario Combinatorics Workshop (OCW) is a conference where researchers working in combinatorics gather to share their research interests and exchange ideas. This workshop aims at providing a friendly environment for graduate students to give conference presentations, learn about different topics in combinatorics, and meet combinatorialists from Ontario and surrounding areas. The workshop consists of three one-hour invited talks, and several sessions of 20-minute contributed talks.

Peter Rodney Book Prize

The best talk given by a student at the Ontario Combinatorics Workshop will be awarded the Peter Rodney Memorial Book Prize. This prize of a book and memorial book plate is given in honour of Dr. Peter Rodney (1965-1995).

Dr. Rodney graduated from McGill University, and then obtained his Masters and Ph.D degrees in Combinatorics, from the University of Toronto. He graduated in 1993 and went on to do postdoctoral research at the University of Vermont. He then continued to work in both the public and private sectors, using discrete mathematics, cryptography, and number theory.

Dr. Rodney had a deep appreciation for probability theory and was an avid card player. He died unexpectedly at the age of 30. His friends and family created a fund in his memory whose proceeds finance this book prize.
