Geometry Through History: Euclidean, Hyperbolic, and Projective Geometries, a book for students and professionals interested in geometry and its development in the West since 300 B.C., was published in April 2018 by Springer International.
A paper in the College Journal of Mathematics about the ubiquity of projective geometry and how we can exploit that in our courses appeared a couple of years ago.
In 2017, my research paper on contructing affine Lie algebras appeared in Communications in Algebra. Reprints are available here.
Currently, I am working on a textbook for a second course in linear algebra.
