Paul Dirksen, a pioneering computer scientist at the University of Waterloo, passed away on April 8, 2023. He was 83.

Paul was born in 1939 in Saskatoon, Saskatchewan to German Mennonite immigrants, and grew up in Waterloo. He was one of the first students at the University of Waterloo, graduating with a B.Sc. in Applied Mathematics in 1963 and a M.Sc. in Computer Science in 1964. Paul’s professors and mentors Ralph Stanton and Wes Graham encouraged him to pursue a career teaching computer science at Waterloo, leading to a decades-long career.  

Paul was a vital part of UW computing history. He was one of the developers of the WATFOR and WATFIV compilers for the IBM 360 mainframe system in the late 1960s. While a previous team had developed an earlier WATFOR for the IBM 7040, the 360 became the foundation architecture for several generations of IBM mainframes.

Waterloo’s WATFOR/WATFIV made the university internationally famous, with over 3,000 customers in 60 countries worldwide: mostly universities and large engineering or manufacturing firms. Along with Paul Cress and Wes Graham, Paul co-authored the FORTRAN-IV with WATFOR and WATFIV textbook, which was Prentice-Hall’s best seller for many years.

Paul was recruited to the University of Manitoba and spent a few years there, but at Wes Graham’s urging he returned to Waterloo in 1972 to help run the Computer Centre – later named the Department of Computer Services (DCS) after Paul succeeded Wes as Director. DCS ran the iconic IBM 360/75 mainframe, housed in the “Red Room” that occupied most of the lower floor of the Math & Computer building.

Waterloo alumnus and WATCOM co-founder Ian McPhee (MMath 1979) remembers working in Wes Graham’s Computer Systems Group, where he was assigned to enhance WATFIV with Structured Programming language extensions, making it WATFIV-S. “Paul invested quite a bit of time teaching me practical skills,” he recalls. “I always appreciated his mentorship and warm, down-to-earth manner.”

During the 1970s, Paul received international recognition and prestige in Computer Science, including the ACM (Association for Computing Machinery) Grace Murray Hopper Award for young innovators. Despite his growing renown, he was always willing to collaborate on projects, provide leadership, and work closely with students.

Together, Paul, Wes Graham, and Don Cowan started the Waterloo Foundation for the Advancement of Computing (WATFAC), which sponsored development of several software products to enable computing in education. WATFAC also provided summer fellowships for leading computer science and math high school teachers in the Waterloo Region, helping to build teaching capacity in the new field in the Waterloo region and beyond. These local teachers were encouraged to nominate talented math and computer science students for WATFAC summer fellowships, often leading to these students applying to Waterloo’s math and computer science programs for their university education. After Wes Graham’s death in 1999, the WATFAC board voted to wind up the foundation and contribute its assets as core funding of the Graham Trust at UW.

During the 1970s, Wes, Don, and Paul also collaborated to start a book publishing business, WATFAC Publications Limited. It published textbooks and manuals to enable the use of the many software tools for education developed by UW’s Computer Systems Group (CSG), DCS, WATFAC, and later WATCOM. In addition to his UW duties, Paul managed the publishing company for many years as its president.

In his spare time, Paul loved being outside in the garden and on the family farm, planting and harvesting corn, tomatoes, potatoes, and more. Paul and his wife Sandra loved classical music and were patrons of the Waterloo Symphony Orchestra for many years. Paul loved jogging and cycling, taking yearly trips to Europe.

He was an enthusiastic traveler, both near and far: besides family camping trips, road trips to Florida, and summers in Muskoka at Scarliffe lodge, Paul and Sandra enjoyed exploring Nova Scotia, Hawaii, Dominican Republic, New Zealand, and Antarctica. One of the great pleasures of Paul’s life was becoming a grandfather, or Papa: a privilege he took on with joy, love, and undivided attention.

Throughout all of his life, whether working, playing, or building a family and community, Paul is remembered as a down-to-earth, kind, warm-hearted, generous man with a zest for life and a willingness to mentor staff and students.

He is survived by his best friend and wife of 58 years, Sandra. He will be profoundly missed by his children David, James, and Heidi (Chris) and grandchildren Nathan and Mackenzie, as well as his brother Eric (Dee Anne) and family.

Cremation has taken place. A celebration of life will be held on Saturday June 3, 2023, at 3:00 p.m. at the Dirksen family home. Attendees are asked to confirm attendance in advance with Sandra Dirksen. In lieu of flowers, donations to KW Symphony Orchestra, the Humane Society, or Grand River Hospital may be arranged through the Erb & Good Family Funeral Home.

Futures Forum to be held May 10

The School of Planning will be hosting the inaugural Futures Forumon May 10. The Futures Forum focuses on the intersection between public engagement and technology and promises to be a day of learning, networking, and discussion. The forum will highlight opportunities and challenges of public engagement, as viewed through the lens of technological, socio-economic, and political changes.

The conference opens at 8:30 a.m. Professor Markus Moos, Director, School of Planning, will be the event's host and moderator.

Delivering the keynote address will be Biana Wylie, Partner, Digital Public and Co-founder, Tech Reset Canada, whose remarks are entitled "Public Engagement, Technology and the Art of Living Well Together."

"The narrative focus of the last political century has been defined by rights – civil, to the city, digital, and more," says the talk's abstract. "To deliver on the opportunities that democracy affords us, the next century will need to focus as much energy, if not more, on responsibilities, the flip side of the rights coin. Through this effort, public institutions can expand and bloom. Without this effort, they will continue their decline. An increase in populist tactics is arriving from people all along the political spectrum, seeking to leverage this moment to hold onto power. The time for your resistance to this situation is now. Urban planning, as one of the professions focused on defining and supporting the ways we live together, has a significant role to play in the development of a more defensible practice of democracy at the local level, including defining if and how to use technology in these efforts." 

Following the morning keynote and lunch will be two afternoon panel sessions, “Digital citizen engagement: The good, the bad, and the in- between" and “Paying for it, Collectively: Municipal Finance and Public Engagement." The closing session is entitled “What have we learned? A Forum Conversation."

This in-person event will be held on the Waterloo campus (locations TBC). Registration information is available on the event website.

This event is open to all, but might be especially relevant to faculty, students and professionals in planning, urban/civil engineering, urban tech, digital societies, public engagement, and any related industries. 

Gautam Kamath among eight Canada CIFAR AI Chairs named Vector Institute Faculty Member

By Joe Petrik. This article was originally published on Waterloo News.

Cheriton School of Computer Science Professor Gautam Kamath has been named a Canada CIFAR AI Chair and a Vector Institute Faculty Member in recognition of his contributions to differential privacy, machine learning and statistics. He is among eight outstanding researchers in the latest cohort of Canada CIFAR AI Chairs to receive this prestigious national recognition.

“Congratulations to Gautam on becoming a faculty member of the Vector Institute and on being named a Canada CIFAR AI Chair,” said Raouf Boutaba, professor and director of the Cheriton School of Computer Science. “Gautam’s research focuses on developing solutions for trustworthy and reliable machine learning and statistics. The fundamental work he and his students conduct is critically important as it allows useful insights to be drawn from data while preserving privacy of sensitive personal information.”

These recent appointments bring the number of Canada CIFAR AI Chairs to 126, continuing to grow Canada’s robust artificial intelligence research ecosystem and advancing Canada’s global leadership in artificial intelligence.

“Canada’s AI ecosystem has grown tremendously since the launch of the Pan‐Canadian AI Strategy six years ago,” notes Elissa Strome, executive director of Pan‐Canadian AI Strategy at CIFAR, in a media release issued today. “Central to the strategy has been the recruitment and retention of excellent researchers at Canada’s three national AI institutes, who in turn attract next‐generation talent as well as commercial investments in this globally in‐demand field. We’re excited about the contributions of these new and renewed chairs, who will continue to advance Canada’s global leadership in AI, a technology that when used responsibly holds terrific potential to address some of humanity’s greatest challenges.”

“Attracting world-class AI talent to Canada is a top priority at Vector," said Melissa Judd, vice-president of Research Operations and Academic Partnerships at the Vector Institute. "The calibre of the three newly appointed CIFAR Chairs from Vector, including Gautam Kamath, speaks to the efforts of institutions like the University of Waterloo to give researchers an environment in which they can take their work to the next level. Vector is proud of its partnership with the University of Waterloo and the University's dedication to both elevating existing AI researchers and growing the next generation of top AI talent in Ontario.”

About Professor Kamath’s research

Kamath is an assistant professor at the Cheriton School of Computer Science in the Faculty of Mathematics. He obtained his PhD and SM degrees in Electrical Engineering and Computer Science at MIT. He leads The Salon, a research group of postdoctoral fellows, graduate students and undergrads who study statistics, algorithms, machine learning, and optimization.

Statistics and machine learning are being used ever more commonly in a variety of disciplines from the physical and social sciences to the humanities, at scales from small groups to entire populations, across sectors as diverse as government, finance and health. The data on which statistics and machine learning techniques are applied often is both sensitive and confidential and, as such, can attract the attention of malicious individuals and groups.

The demands of modern data analysis — most notably guaranteeing data privacy — quite simply were not envisioned when classical statistical methods were developed. In fact, if statistical techniques are applied without consideration for privacy, information can be leaked about the data, and in extreme cases even actual data points themselves upon which the statistical estimations are based.

Kamath’s research revitalizes the toolkits needed in the modern data era, addressing fundamental problems in the realms of robustness and data privacy, by developing guarantees for trustworthy and reliable machine learning and statistics. He and his students have made seminal and significant contributions to both areas — in the theoretical foundations of data privacy as well as in its practical applications — initiating broad new research fields, and contributing core components to deployments that touch the sensitive personal information of hundreds of millions of individuals.
