Remembering Professor Edward Lank

Professor Lank delivering a talk at the 2018 Cheriton Research Symposium.

A message from the Cheriton School of Computer Science.

We are saddened to announce that our dear friend, mentor and colleague Edward Lank, Professor at the Cheriton School of Computer Science, passed away on March 21, 2022 at the age of 49.

Professor Lank was born on November 28, 1972 and grew up in Ebenezer, a village northwest of Charlottetown on Prince Edward Island. He received an honours bachelor’s degree in physics in 1994 from the University of Prince Edward Island and a PhD in computer science from Queen’s University in 2001.

After completing graduate studies, Professor Lank worked as a postdoctoral researcher at the Xerox Palo Alto Research Center. In January 2002, he began his academic career as an Assistant Professor at San Francisco State University in the Computer Science Department. While at San Francisco State University, he received a National Science Foundation Career Award, the Foundation’s most prestigious award that recognizes and supports the early career development of scholars destined to become academic leaders.

Professor Lank joined the Cheriton School of Computer Science as an Assistant Professor in June 2006. He was promoted to Associate Professor in July 2011 and to Full Professor in July 2018. With his colleague Michael Terry, Professor Lank co-founded À¶Ý®ÊÓƵ HCI, a university-wide consortium of faculty members and students who conduct research in the field of human-computer interaction.

Professor Lank’s primary research interests were in intelligent user interfaces; mobile, multi-touch and free-space gestural interaction; and movement and input modelling in interfaces. His projects included work in mechanisms for leveraging reject rates to increase the perceived reliability of recognition-based user interfaces. He explored the design of free-space gesture input languages such as motion gestures and mechanisms for treating motion gestures. He and his students explored techniques for predicting target locations in goal-directed movements such as pointing and speed profiles in constrained movements in interfaces.

Professor Lank was interested in all aspects of human-computer interaction. His work also explored persuasive technologies, sustainability, computer-supported cooperative work, usable privacy and security, sketch and diagram recognition, and human-in-the-loop information retrieval.

The consummate graduate advisor, Professor Lank placed the interests of his students foremost by providing guidance and encouragement so they could perform research at their fullest potential. His goal was to mentor students so they become individuals who conduct strong research and prepare papers as independent scholars and scientists.

From 2018 to 2021, Professor Lank held a Cheriton Faculty Fellowship, a prestigious recognition that supports the work of leading faculty at the School of Computer Science. He was also an Inria International Research Chair attached to Équipe LOKI at Inria Lille-Nord Europe in Villeneuve d’Ascq, France. Alongside his many research positions, he also served as Associate Director of Undergraduate Studies from 2011 to 2013 and as Associate Director from 2013 to 2015 at the Cheriton School of Computer Science.

Professor Lank is survived by his beloved wife, Michelle, and his loving daughters, Olivia and Charlotte. He rests at Maison du Funeraille, Mouvaux, France. A memorial service was held on Saturday, March 26, 2022.Ìý

We extend our deepest sympathies to Professor Lank’s family.

It's a date: À¶Ý®ÊÓƵ encouraged to adopt ISO 8601 International Date Format

A message from Information Systems & Technology (IST).

Currently, a mix of date formats is used across campus, leading to confusion when viewing the date, or making it difficult for system-to-system communication. For example, the date 03/05/2022 can be interpreted as March 5, 2022, or May 3, 2022.

In 1997, the Canadian Federal Government adopted the International Organization for Standardization (ISO) 8601 standard, which sets out an internationally agreed upon way to organize dates, formatting them in descending order of Year, Month, Date (YYYY-MM-DD), using hyphens instead of slashes. This standard minimizes ambiguity around dates and allows systems and software to integrate more smoothly.

With the support of the Computing Technology and Services Committee (CTSC) and the University Committee on Information Systems and Technology (UCIST), Information Systems & Technology (IST) will be implementing the ISO 8601 date standard across systems to the extent possible. Changes and impacts to individual systems will be announced in the usual manner.

All IT administrators are encouraged to review the ISO 8601 standard and implement this change where conditions and resources permit. .

Q and A with the experts: Ukraine crisis reignites debate over Line-5 pipeline

Amid rising oil prices stemming from sanctions on Russia for its invasion ofÌýUkraine, the Canadian government is pressing Michigan to end its opposition to the transnational Line-5 pipeline. À¶Ý®ÊÓƵ professor Grant Gunn explains the environmental concerns regarding the pipeline being situated at the bottom of lakes that annually freeze over.Ìý

What is the current dispute involving the Line-5 pipeline?

The clash centres around public concernsÌýover the safety of the transnational 8km stretch of pipeline, referred to as the Line-5 pipeline, running underwater through the internationalÌýStraits of Mackinac connecting Lake Huron and Lake Michigan.

The State of Michigan wants to halt the operation and revoke Enbridge's easement to use the lake bottom for its pipelines. This effortÌýcontinues to fuel a legal dispute between Canada and the United States.ÌýAt stake is the ecological health of the Great Lakes and a project moving 540,000 barrels of oil daily, which are increasingly in-demand given rising oil prices due to sanctions from Russia's invasion ofÌýUkraine.Ìý

What specifically do Michiganders fear about this particular underwater pipeline?

Besides the fact that every oil spill poses an immediate threat to every part of an aquatic ecosystem, Line-5 is in a somewhat unique position as the nexus of two ice-covered freshwater lakes. Since the lakes freeze over in the winter, our recent study explored the storage capacity of ice in the Straits, and what might happen if a spill were to occur at various levels of ice cover.Ìý

Several models have already been developed to predict the amount of shoreline affected in a potential spill in open-water conditions. But our study examined the consequences of a spill happening when the Straits are totally frozen over. We worked out how oil could be stored beneath the ice. If such a spill were to happen, it would lead to complicated detection and clean-up strategies. So, there is some danger that if oil is released under ice, it would have an even more devastating impact on the environment than a spill in open water.Ìý

What will determine if the pipeline will be shut down?

Following an incident involving a boat's anchor damaging the line, public pressure ledÌýMichigan's governor to temporarily order Calgary-based Enbridge Inc. to shut down the pipeline that supplies refineries in Sarnia, Ontario, and has moved to revoke the 1953 easement to operate the pipeline on the lakebed. Negotiators on both sides must consider that the Line-5 pipeline is currently 70 years old. Plans for a new tunnel project to enclose a replacement to Line-5 have been proposed to protect the aquatic environment in the event of a leak. But for now, that's only a plan.Ìý

Political ideology and disinformation also play a part in how this will play out. In a parallel study of ours, we got a sense that not everyone was equally informed about the risks. There is a lot of disinformation in the debate.ÌýIdeological, social and cultural factors influence perceived risk to pipelines. Russia's war onÌýUkraineÌýand the lack of supply of oil are likely to polarize decision-makers even more.Ìý

Grant Gunn is an Assistant Professor in Geography and Environmental Management. His research aims to improve the retrievals of physical components of the Cryosphere, including permafrost (active layer thickness, timing of thaw/refreeze) andÌýice parameters in sub-Arctic and Arctic environments.
