Don joined Queen’s University on July 1st, 2015, reporting to the Vice Principal (Research) – he has responsibility for advanced research computing across the university, including the Centre for Advanced Computing (CAC). His primary mission is to help the Queen’s research community adopt leading edge information technology.
Prior to joining Queen’s Don had a 30+ year career with IBM Canada culminating as the Research Executive for Canada. During his time at IBM he held a wide range of technical, sales and management positions. The majority of his career has been spent working closely with the higher education research community, various funding agencies and all levels of government. In the early 1990’s he introduced the highly successful “IBM ThinkPad University” student mobile computing program in Canada. In 2003 he established IBM’s Life Sciences unit in Canada as part of a global effort, working with medical researchers in universities and research hospitals across the country.
In April of 2012 Don was instrumental in launching the IBM Canada Research & Development Centre. This R&D Centre is unique in the IBM family of Research sites in that most of the research staff members are located on university campuses working collaboratively with university research personnel. In parallel with the creation of the Centre he was a driving force behind establishing the Southern Ontario Smart Computing Innovation Platform (SOSCIP) – a consortium consisting initially of seven leading research universities and IBM. Today SOSCIP boasts an impressive collection of advanced research computing platforms, including the largest supercomputer in Canada, and has a membership of 14 universities and colleges.
Don received a BSc (Mechanical Engineering) from Queen’s University in 1982, and an MBA, also from Queen’s, in 1984. Married for 34 years, he is the father of three children in their twenties.
