    More than a hundred students spent the weekend working in teams learning to detect fraud as part of the inaugural Scotiabank Data Science Discovery Days competition.

    The event, which took place virtually and in Mathematics 3 from January 20th to January 22nd, invited teams of students from across campus to analyze large amounts of data in a project that mimics the real world work they would do in data science careers.

    “Scotiabank and the University of Waterloo share a passion for innovation,” says Yannick Lallement, Scotiabank’s Vice President for Corporate Functions Analytics and AI/ML Solutions. “We are pleased to partner with UW on programs that encourage students to engage with applied data and analytics. The enthusiasm, creativity, and technical skills that UW brought to this challenge impressed me a great deal.”

  3. Jan. 19, 2023In Memoriam: Ken Seng Tan
    Dr. Ken Seng Tan

    We are very greatly saddened to announce that our beloved friend and colleague, Professor Ken Seng Tan, passed away on January 1, 2023. 

    Ken Seng Tan completed his BMath, MMath, and PhD in Actuarial Science at the University of Waterloo. His 1998 doctoral thesis won an award for Oustanding Achievement in Graduate Studies. It also marked the beginning of a lifelong friendship and collaboration with his supervisor, Phelim Boyle. 

    Ken Seng joined the Department of Statistics and Actuarial Science as faculty in 1998. He held a Canada Research Chair in Quantitative Risk Management from 2005 to 2010, and a University Research Chair from 2010 to 2015. From 2006 to 2015 he was Associate Director of the Institute for Quantitative Finance and Insurance and its successor, WatRISQ. Ken Seng also held a longterm visiting position at the Central University of Finance and Economics in Beijing, where he was active in supporting Chinese actuarial education and research.

Research interests

Professor Thompson works primarily in survey methodology and sampling theory. Her book Theory of Sample Surveys describes the mathematical and foundational theory in detail; it also contains a systematic approach to using estimating functions in surveys, and a thorough discussion (with examples) of the role of the sampling design when survey data are used for analytic purposes.

Estimation for stochastic processes has been another theme of her research. These twothemes come together in aspects of inference from complex longitudinal surveys. Issues in the design of longitudinal surveys to support causal inference are central to work on the International Tobacco Control Survey, with which Professor Thompson has been involved since 2002. She studies the application of multilevel models and longitudinal models with time-varying covariates to complex survey data, including the best ways to adapt the estimating functions systems for use with survey weights, and the use of resampling techniques to provide accurate interval estimates.

She is also currently collaborating on projects in survival and multistate models and the design of behavioural interventions on random networks.
