I am an assistant Professor in the Mathematics Department at Southern Connecticut State University which houses the GeoGebra Institute of Southern Connecticut.(http://www.southernct.edu/academics/schools/arts/departments/mathematics/geogebrainstitute/index.html) We regular hold workshops for Secondary and College level mathematics teachers and an annual conference. As an instructor of a range of classes, I use GeoGebra in classes such as Pre-Calculus, the Calculus Sequence, and a variety of upper level undergraduate mathematics courses. I also find GeoGebra useful in my Discrete and Computational Geometry research.
