Ken Kelley is the Edward F. Sorin Society Professor of IT, Analytics, and Operations (ITAO) and the Senior Associate Dean for Faculty and Research in the Mendoza College of Business at the University of Notre Dame. Professor Kelley is in the analytics group within the ITAO Department and works to advance analytic methods in his research in a variety of ways from a variety of perspectives to improve the methods used in human-centered research, from the foundational area of psychology to applied areas in business. His work crosses several traditional disciplinary boundaries, which he believes is important when considering various aspects of the human condition. More specifically, he evaluates, improves, and develops methods to better study human-centered research from a methodological perspective. The entire effort is in the data science space, particularly from the psychometric and statistical traditions of framing inferential questions. His most significant methodological contributions are in research design involving the interplay between effect size, confidence intervals, statistical significance, and sample size planning. My work depends heavily on statistical computing, with most of the methods I have developed implemented in R packages (e.g., MBESS, BUCCS, SMRD). In addition to methodological work, he collaborates in a variety of human-centered areas in which I develop needed or apply advanced or nonstandard methods to best address questions. Kelley is co-director of the Human-centered Analytics Lab (HAL) in the Mendoza College of Business. HAL is an interdisciplinary mash-up of technology, psychology, methodology, and business.
Professor Kelley is an Accredited Professional Statistician™ (PStat®) by the American Statistical Association, former associate editor of Psychological Methods, recipient of the Anne Anastasi early career award by the American Psychological Association's Division of Evaluation, Measurement, & Statistics, an elected member of the Society of Multivariate Experimental Psychology, and a fellow of the American Psychological Association. Currently, Professor Kelley is a faculty affiliate of iNDustry Labs, which is an initiative to help advance the regional economy, particularly as they move toward more advanced manufacturing.
