Research Interests

I have studied hyperbolic dynamical systems and the relationships between dynamical invariants computed using the methods of symbolic dynamics and homological invariants computed using methods of homological algebra and algebraic K-Theory. I also have an interest in representations of mathematical algebraic systems in computer algebra systems.

Other Activities

While I was a faculty member at the University of Arizona Sierra Vista campus, I was the director of the Patterson Observatory. My friend, Mr. David Healy was very kind to Dr. Zizza. So, I have more than a passing interest in things astronomical.
