Dan Pitonyak ’08
Associate Professor of Physics
Co-Chair of Chemistry and Physics
Dr. Pitonyak’s student-faculty research focuses on computational nuclear physics. His work attempts to understand the 3-dimensional internal structure of visible matter. Dr. Pitonyak and his students write code in Python to compute high-energy particle collisions and analyze how models fit experimental data. This enables them to extract information on the elementary particles that make up objects like the proton.
