He obtained his BA from the Franklin & Marshall College, Lancaster, PA, (1955), his Master of Science (1964) and the Ph.D. in Physics (1966), both from the University of Maryland, College Park, MD. He has spent most of his active career in X-ray astrophysics with emphasis in the development of space-borne instrumentation. He has pioneered two types of instruments which have since been used extensively in the field: the large area multiwire gas proportional counter and lightweight conical foil X-ray mirrors. He has been principal investigator in several satellite missions, including NASAs Astro-1 mission, flown on the Space Shuttle in December 1990, and the US/Japan collaborative spectroscopy missions ASCA and Astro-E (the latter in preparation). His scientific interests include Fe K lines in the spectra of clusters of galaxies, spectra of AGN and the search with ASCA for hard, AGN-like nuclear sources in nearby spiral galaxies.
