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.

A few of my other favorite things:

- The annual mathematics department alumni newsletter, the Mackinac Gazette.
- The Mathematical Association of America's newsletter, FOCUS.
- Colleagues who are rethinking grading, such as with the Grading Conference.
- Posting about open resources for calculus.
