Research interests

Professor Salzer has broad research interests in the area of extragalactic astronomy. His current research focuses are in the area of abundances in galaxies and star-formation in the nearby universe. His abundance research involves studying the metal content of hundreds of galaxies to understand the demographics of chemical enrichment as well as to measure the evolution of abundances to modest lookback times. His current star-formation studies focus on measuring the rate at which stars are being born in hundreds of nearby gas-rich galaxies, with the goal of carrying out an unbiased census of star formation in the local universe. In addition, he has ongoing interests in Seyfert Galaxies and AGN, Blue Compact Dwarf galaxies, and the spatial distribution of galaxies in the local universe, with an eye toward the affects that galaxian environment plays in shaping the properties of galaxies.

About John J. Salzer

Dr. Salzer joined the IU Astronomy faculty in 2009. He previously was a professor and department chair at Wesleyan University. He earned his undergraduate degree from Coe College (Cedar Rapids, IA), an M.S. in Physics from Iowa State University, and his Ph.D. in Astronomy from the University of Michigan. He has served on numerous committees and panels, and was bestowed with a Presidential Faculty Fellow Award by President Clinton in 1995.
