Dr. Dan Pitonyak
Assistant Professor of Physics
Academic Areas of Expertise:
- Atomic and Nuclear Physics
- Elementary Particle Physics
- Analytical Mechanics
- Electricity and Magnetism
- Quantum Mechanics
Courses Taught at LVC
PHY 103 General College Physics
PHY 104 General College Physics
PHY 211 Atomic and Nuclear Physics
PHY 212 Electronics
PHY 311 Analytical Mechanics
PHY 312 Analytical Mechanics
Research Topics:
Computational nuclear physics is the focus of our student-faculty research. Our work attempts to understand the 3-dimensional internal structure of visible matter. We write code in Python to compute high-energy particle collisions and analyze how models fit experimental data. This enables us to extract information on the elementary particles that make up objects like the proton.
