  1. July 1, 2022The Department of Statistics and Actuarial Science is pleased to welcome Zelalem Negeri as an Assistant Professor
    Zelalem Negeri

    NEGERI, Zelalem [BSc. (Statistics), 2011, Addis Ababa University; MSc. (Statistics), 2014, Addis Ababa University; MSc. (Statistics), 2015, McMaster University; Ph.D. (Statistics), 2019, McMaster University] has joined the Department of Statistics and Actuarial Science on July 1, 2022, as an Assistant Professor. Zelalem was a Post-Doctoral Fellow at McGill University’s Department of Epidemiology, Biostatistics and Occupational Health from 2019 to 2021, and worked as a Biostatistician at Veristat, LLC, a global clinical research organization before joining the University of Waterloo. His research interest focuses on developing and validating statistical methods for applications in public health research, with an emphasis on both aggregate data and individual participant data meta-analyses of diagnostic and screening test accuracy studies.

    Yue (Henry) Weng, Eckler winner

    The Department of Statistics and Actuarial Science is pleased to announce Yue (Henry) Weng as the winner of the Samuel Eckler Medal in Actuarial Science. Henry graduated in Spring 2022 with a triple major in Actuarial Science, Statistics, and Combinatorics & Optimization.

    Award description: 

    This prize was established to recognize the contribution of Samuel Eckler to the actuarial profession and is provided by Eckler Partners. The medal, which is cast in gold, is awarded each year to the outstanding graduating student in Honours Actuarial Science.

    "Henry is one of the most talented students I have taught at the University of Waterloo. His analytical skills are amazing. A well-deserved medal for him."

  3. June 21, 2022Pengfei Li Won the 2022 CRM-SSC Prize in Statistics
    Pengfei Li

    Professor Pengfei Li of the Department of Statistics and Actuarial Science at the University of Waterloo was the winner of the 2022 CRM-SSC Prize in Statistics. The award recognizes a statistical scientist’s excellence and accomplishments in research during the first fifteen years after earning his/her doctorate (or equivalent degree). It is awarded annually by the Centre de recherches mathématiques (CRM) and the Statistical Society of Canada (SSC) and is widely viewed as the most prestigious honor for mid-career researchers in the field of statistics in Canada. The citation of the award reads:

    “To Pengfei Li, for ground-breaking and pioneering research contributions to the EM-test for the order of finite mixture models; for original and creative methodological developments in the areas of the empirical likelihood, density ratio models, statistical genetics, non-probability sampling; for exceptional research productivity; and excellence in statistical education.”

    The award was announced at the 2022 Annual Meeting (virtual) of the Statistical Society of Canada. An article detailing the research and some personal stories of Professor Pengfei Li will become available later in the summer on the SSC website.

Research Interests

My main research area is applied probability. Currently I focus on understanding the relation between the random locations (e.g., the location of the path supremum, the hitting times, etc.) and the probabilistic symmetries of stochastic processes/random fields, such as stationarity, self-similarity, exchangeability, etc. I am also working on characterizing these symmetries using various tools including extreme value theory and ergodic theory.

More generally, I am enthusiastic about various problems in probability, such as random algebraic topology, limit theorems and financial mathematics. I am also interested in the applications of probability in statistics, physics, econometrics and actuarial science.
