Kenneth Joseph Ryan's Webpage

Welcome to my webpage! I am a Professor of Statistics and the Chair of the Department of Statistics at WVU. I also am an Associate Director in the newly formed School of Mathematical and Data Sciences and a Fellow of the American Statistical Association.

Fall 2023 Teaching:

• STAT 215: TR 10:00am-11:15am. See eCampus for additional course information.
• Office hours: TR 11:30am-12:30pm or by email appointment.
• I also manage the Statistics Tutoring Center for help mainly in STAT 111, 211, 215, and 312.

Research:

You can trace my mathematics genealogy back to Poisson, Lagrange, Laplace, Euler, Johann Bernoulli, and Jacob Bernoulli. My research interests include semi-supervised learning and design of experiments. Selected papers are below. My CV and Google Scholar Profile have a complete list of refereed publications.
