About Me

I am an Associate Professor of Mathematics at California State University, San Bernardino (CSUSB).  I joined the faculty at CSUSB in 2016.

I am interested in many mathematical areas.  I enjoy using algebraic tools from linear algebra, number theory, and group theory to study problems in geometry and cryptography.  For both teaching and research, I frequently program in Sage.  I always use GeoGebra in my teaching.  I am currently writing some texts in linear algebra and geometry.

I am very interested in research in math education, in particular, theories on learning and teaching of mathematics, especially as they relate to linear algebra.

Previously, I had been a Postdoctoral Visiting Professor of Mathematics at the University of Oklahoma. I grew up in Denver, Colorado, received my undergraduate degrees in mathematics and physics from the University of Chicago, and my Ph.D. in mathematics from the University of Michigan.
