Professor(retired) Alan L. Horwitz

I am currently retired from Penn State's
in Media, PA, where I was a mathematics professor for 28 years.
I received my PhD in mathematics from Temple University in 1984. Some of my research interests are in means, ellipses inscribed in convex quadrilaterals, and ratios of polynomials with all real zeros.
