Rate My Professor Andrew Shallue

Andrew Shallue is Professor and Chair of the Department of Computer Science at Illinois Wesleyan University, a position he has held since his appointment to the faculty in Fall 2009. He earned a B.A. from Gustavus Adolphus College and a Ph.D. from the University of Wisconsin-Madison in 2007. Shallue's research focuses on algorithmic number theory and its applications to cryptography, particularly in the areas of pseudoprimes, Carmichael numbers, and probabilistic tests for primality involving liar counts and Frobenius pseudoprimes. His contributions include developing efficient algorithms for tabulating these structures, which have practical implications for cryptographic protocols and number-theoretic computations.

Shallue has published extensively in leading journals. Key works include 'Advances in tabulating Carmichael numbers' in Research in Number Theory (2025, with J. Webster), 'Tabulating Carmichael numbers n = Pqr with small P' in Research in Number Theory (2022, with J. Webster), 'Average Liar Count for Degree-2 Frobenius Pseudoprimes' in Mathematics of Computation (2020, with A. Fiori), 'Tabulating pseudoprimes and tabulating liars' in ACM Transactions on Algorithms (2016), and 'Counting composites with two strong liars' (with E. Bach). He received the Dick Lehmer Award for the best talk at the 2016 West Coast Number Theory Conference, titled 'Average liar count for degree-2 Frobenius pseudoprimes.' Other honors include the Project NExT Fellowship from the Mathematical Association of America (2009-2010), a Fall 2009 Course Development Grant, Spring 2011 and 2012 ASD Grants, and a Fall 2013 information literacy grant through the Mellon Center. As department chair, Shallue oversees the Computer Science program, supports undergraduate research, and contributes to university governance, including service on the Council on University Faculty.
