Research

Dr. Holtzman has interests in the fields of stellar populations, the structure of galaxies, and cosmology. He is an experienced user of the Hubble Space Telescope, and participated as a member of the Instrument Definition Teams for the WF/PC and WFPC2 cameras, and is a member of the Science Oversight Committee for the planned WFC3 camera. He studies the history of galaxy assembly of nearby galaxies by deriving star formation histories based on the distribution of stars in color-magnitude diagrams. He is also working on incorporating observed chemical abundances in an attempt to derive a self-consistent model of the star formation and chemical evolution history of nearby galaxies. He also works on more distant galaxies, attempting to understand the mechanisms of spiral galaxy formation through studies of their structure and integrated stellar populations. He has also worked on young, massive, compact clusters in external galaxies.

Dr. Holtzman has been actively involved in the SDSS-II supernova survey. He is currently involved in planning for the SDSS-III APOGEE survey.

Dr. Holtzman also has interests in observational techniques and instrumentation. He is the Instrument Scientist for the ARC 3.5m Telescope and is responsible for the operation of the NMSU 1.0m Telescope at Apache Point Observatory.

Teaching

Dr. Holtzman teaches both undergraduate and graduate classes. At the undergraduate level, he is a popular teacher for Introductory Astronomy (ASTR 110). At the graduate level, he has been teaching the Observational Techniques (ASTR 535) class for first year graduate students, and a class on Galaxies (ASTR 616) for upper level students. He had led seminars on The Science Behind the SDSS-II Supernova Survey, Nucleosynthesis, and Globular Clusters.
