My research is in the field
of experimental high energy X-ray astrophysics. High energy astrophysics
studies the evolution of stars and galaxies by detecting and deciphering
their emission of energetic particles and radiation. X-rays and gamma-rays
are the most energetic forms of radiation. They are produced in unique
environments such as supernova explosions and the immediate vicinity of black
holes. The emissions can tell us what is happening in these extreme
environments which are impossible to duplicate on Earth. I am particularly
interested in building semiconductor radiation detectors and using these
efficient detectors to study how X-rays and gamma-rays are produced around
black holes and neutron stars. Many Holy Cross students have participated in the
experimental and analysis work in my lab. Lab Alumni
