The 2022-2023 academic year was my silver anniversary at Grand Valley: 25 years. I've been fortunate to work at GVSU for my entire professional career and to have the opportunity to pursue a range of interesting projects. I enjoy teaching a wide variety of classes; in 2024-25, that will include 2 sections of Linear Algebra 2 in the fall semester, and 2 sections of TBA in the winter.
My main scholarly and creative focus is my (free, open-source) textbooks, especially Active Prelude to Calculus and Active Calculus (single variable). Each of these books got started on a sabbatical (the first four chapters of ACS in winter 2012, the entirety of APC in fall 2018), and I continue to actively work to improve them. I share some more detail about them on a separate page.
I am also a big proponent of OER (open educational resources), especially free and open-source textbooks. Two of my favorites are by GVSU Math colleagues: David Austin's Understanding Linear Algebra, and Ted Sundstrom's Mathematical Reasoning: Writing and Proof. There are many more fantastic OER math textbooks available at the American Institute of Mathematics Open Textbook Initiative.
