Biography
Dr. Velissaris received his PhD in Particle Physics from University of Rochester in 1995. He was in Military Service. Corps of Engineers (1995-1997). He worked as a Post-doctoral Associate in New Mexico State University Stationed at Brookhaven National Lab (1997-2000). He joined University of Wisconsin-Madison as a Assistant Scientist in 2000. and Monmouth College as a Visiting Assistant Professor in 2005. He is a Lecturer at Department of Physics, UCF since 2006.
Research Areas
Dr. Christos Velissaris is an Experimental Particle Physicist and has worked in electron positron collider experiments at KEK accelerator in Japan as well as in neutrino experiments at Fermi National laboratory. His Research areas concentration were Statistical massive data analysis and gaseous detector operation and development (drift chambers). In his research he tested the “Standard model” of Fundamental Interactions in electron positron collisions by measuring the production of dileptons (muon and tau particles) and. He also studied the “neutrino” particles at Fermi National Laboratory.
Research Opportunities for Students
Dr. Christos Velissaris, currently, at UCF does Undergraduate Research in the following areas:
- Interaction of Radiation with Matter and Radiation detector operation and simulations.
- Medical Physics with emphasis in Radiation Oncology and Medical Imaging (computed tomography and gamma camera) simulations.
- Accelerator and beam dynamics physics in Linear accelerators and Rings.
Past Students have done undergraduate research in optimizing the collimator of a Gamma Camera, studying the beam focusing in a circular accelerator (FODO lattice) and studying the feasibility of using the Lunar Regolith as a Radiation Shield in future Lunar dwellings
