Waterloo’s Department of Applied Mathematics PhD candidate James Petrie is among a group of volunteers who have combined their knowledge to develop Covid Watch, an app that uses Bluetooth to detect when users are in proximity to each other and alerts them anonymously if they were in contact with someone later confirmed to have COVID-19. The app uses privacy-preserving measures so that no one, including the government, can track down who exposed whom.

The following was excerpted from an article published on the website of CS-Can/Info-Can, the nation’s professional society dedicated to representing all aspects of computer science and the interests of the discipline to Canadians.

It’s not about building technology; it’s about finding a solution to an existing problem for the research group of Ihab Ilyas, a professor at the Cheriton School of Computer Science.

University of Waterloo Faculty to Mathematics researchers have developed a new method that enables large insurers to reduce the time spent estimating the financial liabilities of their portfolios from days to hours while achieving high accuracy.

A study details the new method which significantly reduces computational time, but still estimates the financial liability of variable annuity portfolios accurately for business purposes.
