<b>Research Interests:</b> Accretion power (quasars and interacting binary stars), high-energy and nebular astrophysics, astrophysics of gravitational wave sources.

Professor Feigelson has two different research interests. First, he has a long-standing program studying Galactic star formation and early stellar evolution using NASA's Chandra X-ray Observatory. Chandra gives powerful insights into the formation of rich star clusters. Second, he is a leader of the cross-disciplinary field of astrostatistics involving education, conferences, Journal editing, and new methodologies for exoplanet disco

I am an assistant professor of astronomy & astrophysics at The Pennsylvania State University. My research interests focus on understanding the processes of galaxy formation through the use of large surveys and statistics. In particular, I specialize in fitting flexible models to galaxy photometry and spectra, in building and exploring analytical and theoretical models of galaxy evolution, and in learning about and applying astrostatistic

In recent years, I have been collaborating with colleagues in the College of Education to study student learning at the K-12 level in Solar System astronomy. We have developed a learning progression for the middle grades, and have some other interesting results on student ideas in this area.

I study extreme astrophysical events, such as compact binary mergers and core-collapse supernovae, using supercomputer simulations.

My primary research interest is observational cosmology. Please visit my personal page for additional information.

I specialize in the design, build, and launch of high resolution soft X-ray spectrometers on NASA sub-orbital rockets. These instruments act as technology development for the next generation flagship X-ray observatories. My background is in the use of silicon detectors for soft X-ray detection. I have been involved in the development of 3 rocket payloads (OGRESS, WRXR, and tREXS) and am currently working on the design of a 4th (OGRE).
