For her service, she acted as the Executive Officer of Astronomy from 1995 to 1996. Her research interests encompass Near-Field Cosmology and Chemical Evolution of Galaxies, particularly focusing on the Local Group and studying the properties of the distant Universe. She employs high-dispersion spectra obtained from the Keck Telescope to analyze star formation, chemical evolution, and the historical development of nearby stellar systems. Her recent work includes investigating the chemical uniformity of globular clusters in galaxies such as M31 and understanding the role of supernovae in early chemical enrichment of the Universe. Dr. Cohen has made significant contributions to the design and development of instruments at the Keck Observatory, participating in projects that have advanced astronomical research capabilities.
Most Caltech graduate programs are PhD-only. GRE General and Subject tests vary by department; many have made them optional or no longer accept them.
