Prof. Fred Sarazin – Professor of Physics

 I am an experimental nuclear and astroparticle physicist in the subatomic group of the physics department at Mines. My research activity spans about 14 orders of magnitude in energy, from the MeV (1 MeV=10⁶eV) in low-energy nuclear physics to the hundreds of EeV (1 EeV=10¹⁸eV) in cosmic-ray physics. I am also involved in medical isotope production using the USGS 1MW TRIGA reactor at the Federal Center in Lakewood. My research group currently comprises 1 postdoc, 5 PhD students and 1 MS student. I invite you to visit my research pages (listed at the top) for more information. 

On the education side, I regularly teach (Honors) Modern Physics (PHGN300/310) and an introductory class in Astronomy and Astrophysics (PHGN324). In the past, I have also taught Advanced Laboratory II (PHGN326) and Nuclear Physics (PHGN422). For more information, you can visit my teaching page linked above. I also advise a number of senior design students every year. New senior design projects are available to the physics seniors each Fall on Canvas. Interested in some undergraduate research prior to being a senior? Shoot me an email, maybe we can work something!
