Jonathan K. Hodge is a Professor of Mathematics and Dean of the School of Natural Sciences at St. Edward's University. Prior to joining SEU, Dr. Hodge taught mathematics for 19 years at Grand Valley State University, where he also co-directed GVSU's Summer Mathematics Research Experience for Undergraduates (REU). Dr. Hodge earned his Ph.D. in mathematics from Western Michigan University in 2002. In addition to Abstract Algebra: An Inquiry-Based Approach, he is also a co-author of The Mathematics of Voting and Elections: A Hands-On Approach, published by the American Mathematical Society.

Steven Schlicker is a Professor of Mathematics at Grand Valley State University in Allendale, MI. He earned his bachelor's degree in mathematics from Michigan State University and a Ph.D. in mathematics (in group cohomology and algebraic K-theory) from Northwestern University. In addition to being a coauthor of Abstract Algebra: An Inquiry-Based Approach, he is a contributing author to Active Calculus, the primary author of Active Calculus Multivariable, and coauthor of the texts Discovering Wavelets and Linear Algebra and Applications: An Inquiry-based Approach, and of a trigonometry book with Ted Sundstrom.

Ted Sundstrom is Professor Emeritus of Mathematics at Grand Valley State University having retired in 2017 after 44 years of service. He received a bachelor's degree in mathematics from Western Michigan University in 1968 and a Ph.D. in mathematics (ring theory) from the University of Massachusetts in 1973. In 2005, he received the award for Distinguished Teaching of College or University Mathematics by the Michigan Section of the MAA. Besides being a coauthor of Abstract Algebra: An Inquiry-Based Approach, he is the author of Mathematical Reasoning: Writing and Proof, and coauthored a trigonometry book with Steven Schlicker. In 2017, Prof. Sundstrom was the inaugural recipient of the Daniel Solow Author's Award from the Mathematical Association of America for the book Mathematical Reasoning: Writing and Proof.
