Biography

Kari Lock Morgan is an Assistant Professor of Statistics at Penn State.

Lock Morgan received her Ph.D. in Statistics from Harvard University in 2011. She received her A.M. in Statistics from Harvard University in 2007, and a B.A. with Honors in Mathematics from Williams College in 2004.

Kari's research focuses on causal inference, statistics education, and simulation-based inference. A general theme throughout these three areas is that it is now computationally easy to generate thousands of randomizations instantly, and we can and should be taking advantage of this fact to collect better experimental data, to teach statistics in a way that leads to better conceptual understanding, and to more flexibly analyze data for statistical inference. Regarding causal inference, Kari focuses on obtaining comparable groups for causal comparisons, either by design in experimental settings, or by analysis in observational settings. For experiments she primarily works on the topic of rerandomization – the idea that we can improve covariate balance by rerandomizing treatment assignment if balance is not acceptable. For observational studies she primarily works with propensity score methodology. Regarding statistics education, Kari works primarily on improving introductory statistics education, particularly through the use of simulation-based inference, multivariable thinking, and data visualization. Regarding simulation-based inference, Kari conducts research on the effectiveness of these methods as pedagogical tools, and also on the general use of these methods as modern statistical methodology.

Kari Lock Morgan joined Penn State as an assistant professor in 2014, and has contributed most broadly to the field of statistics education. She currently serves on the ASA/MAA Joint Committee for Undergraduate Statistics Education, and has served on the executive committee for the ASA’s Section on Statistics Education, as the program chair for the Electronic Conference on Teaching Statistics (eCOTS), as the Associate Director for Professional Development for CAUSE (the Consortium for Advancement of Undergradute Statistics Education), and as a member of several other national statistics education committees and groups. She has given 28 invited talks or workshops on statistics education, including a plenary address at the 2019 United States Conference on Teaching Statistics and four invited talks at the International Conference on Teaching Statistics. She has also given 20 invited talks on causal inference.
