I grew up in western New York, where I spent most of my youth playing baseball and discovering my love of science (especially physics). It was my passion in both these areas that led me to attend Allegheny College after high school. I majored in physics and mathematics at Allegheny while minoring in philosophy. After graduating with my B.S. in physics and math, I attended graduate school at the University of Notre Dame. While at Notre Dame I began working with Professors Chris Howk and Nicolas Lehner in the area of astrophysics, and in particular, absorption spectroscopy of gas and galaxies. My research focused on using Lyman limit systems to study the circumgalactic environments of galaxies in an effort to understand the physical mechanisms responsible for the circulation gas throughout galaxies, and if these mechanisms have evolved over cosmic time. In the fall of 2011, I joined the Utica College faculty. I am heavily involved in the general physics curriculum and am currently working on updating the astronomy offerings of the physics department. 

Although my baseball playing days are behind me, I have discovered new and exciting sports to occupy my free time. If not in the office, you may find me with my wife on the golf course, the trails, the ultimate frisbee field, the hockey rink, or one of the beautiful lakes in the Adirondacks. 


Research Interests

My astrophysics research interests include:
  • the evolution of galaxies over cosmic time
  • Lyman limit systems and their connection to galaxies
  • the circulation of gas throughout the circumgalactic medium
  • the physical mechanisms driving the accretion of gas onto galaxies
among others...

I am also interested in developing the campus-community relationship to allow for children and young adults to experience science in a fun and interactive way.
