I'm a tenured professor at the University of Wisconsin---Stout, in Menomonie, Wisconsin, USA. I specialize in the overlap of Applied Mathematics and Computer Science, with particular interests in cryptography (the science of codes) and computer algebra systems.
I mostly teach undergraduate courses, but some Master's level courses too, and I hope you'll find my writing style to hold true to the best ideals of good undergraduate teaching: clarity, correctness, simplicity, and a desire to reach as wide an audience as possible. I believe in the famous quote, (mis)attributed to Albert Einstein: "Everything should be made as simple as possible, but not one bit simpler."
In my books and the classroom, I always aim to show as many real-world applications as possible, so that the students will understand how and when they will use this knowledge later in their STEM careers. I'm not afraid to tackle the occasional theoretical question, because sometimes such undertakings can be excellent calisthenics of the mind.
Currently, I'm working on a book for courses called "Discrete Mathematics" or "Discrete Structures," as well as a translation of Sage for Undergraduates into Spanish.
