Waterloo graduate student David Qian, under the guidance of the Faculty of Mathematics’ Ricardo Fukasawa and Jochen Koenemann, introduced optimization techniques based on integer and dynamic programming to surgeons at SickKids hospital. By applying mathematical optimization algorithms, Qian and team advised doctors on the best surgical cut points to minimize the volume-difference between the surgically modified skull, and an ideal skull.

Analyzing trends on Twitter and Google can help predict vaccine scares that can lead to disease outbreaks, according to a study from the University of Waterloo.

In the study, researchers examined Google searches and geocoded tweets with the help of artificial intelligence and a mathematical model. The resulting data enabled them to analyze public perceptions on the value of getting vaccinated and determine when a population was getting close to a tipping point.
