Nathaniel is an Assistant Professor of Statistics at the University of Waterloo (UW) in the Department of Statistics and Actuarial Science, and he is the Director of the BMATH and BCS in Data Science programs. He is also the President of the Statistical Society of Canada's Data Science and Analytics Section. From 2015-2018 Nathaniel held a faculty position at the University of San Francisco (USF) where he was jointly appointed in the Department of Mathematics and Statistics as well as the MS in Data Science program. From 2017-2018 he served as Program Director for their BS in Data Science program. Prior to this, Nathaniel earned BMATH (2010), MMATH (2011) and PhD (2015) degrees in Statistics from the University of Waterloo.
During his career, Nathaniel has also worked as a consultant and instructor within USF's Data Institute and UW's Business and Industrial Statistics Research Group (BISRG). Nathaniel is currently the Director of BISRG. In these capacities he has provided professional training and worked on several projects resulting in collaborations with 20+ organizations. He has also overseen 30+ undergraduate and graduate level data science internships in exploratory data analysis, time series analysis, machine learning, A/B testing and data visualization.
In general, Nathaniel is interested in using data to make decisions, solve problems, and improve processes. Specifically, his research interests lie at the intersection of data science and industrial statistics. He is interested in methodological developments in experimental design and A/B testing, process monitoring and network surveillance, reliability and survival analysis, and the assessment and comparison of measurement systems. Recently Nathaniel has developed a family of comparative probability metrics that may be used in place of traditional hypothesis tests in any setting that requires a comparison of statistical quantities. Applications include the comparison of experimental conditions, the comparison of measurement systems, the comparison of survival experiences and more generally, the comparison of expected and predicted response surfaces.
Nathaniel was the recipient of the 2021 Søren Bisgaard for "Bayesian Probability of Agreement for Comparing Survival or Reliability Functions with Parametric Lifetime Regression Models" which was judged to be the Quality Engineering paper with the greatest potential for advancing the practice of quality improvement. He was also the recipient of the 2020 ASQ Llyod Nelson Award for "Design and Analysis of Confirmation Experiments" which was deemed to be the paper appearing in the Journal of Quality Technology with the greatest immediate impact to practitioners. His talk "Comparing Two Kaplan-Meier Curves with the Probability of Agreement" was awarded the 2019 Shewall Award for best talk at the ASQ Fall Technical Conference. He was also the recipient of the 2017-2018 Best Reliability Paper in Quality Engineering for "Quantifying Similarity in Reliability Surfaces Using the Probability of Agreement".
