Dr. Hardersen is currently serving as an associate professor of space studies at the University of North Dakota’s Department of Space Studies. A member of the faculty since August 2003, Dr. Hardersen teaches a variety of courses while also pursing vigorous, diverse externally-funded research programs and serving as the Director of the UND Space Studies Observatory.
Academically, Dr. Hardersen’s teaching portfolio includes courses that focus on astronomical research methods, observational techniques and instrumentation, remote astronomical observing, an introductory course in solar physics, and a seminar course covering the latest research in astrobiology. A common theme among these courses is teaching students how to think like practicing scientists that includes learning how to read and understand complex research papers, conduct literature reviews, understand and manipulate various types of astronomical data, comprehend and implement of astronomical data reduction techniques, and be aware of the latest research in a given field.
Dr. Hardersen’s research activities include both planetary astronomy and solar physics components. Funded research from the NASA Planetary Astronomy program focuses on the near-infrared spectral and mineralogical studies of certain groups of asteroids in the main asteroid belt, such as populations of basaltic asteroids. In addition, Dr. Hardersen has branched out into solar physics and is pursuing research using ground- and space-based imagery to better understand the rotational nature of sunspots and how sunspot rotation may influence the onset of solar flares.
Service work primarily includes serving on a variety of departmental, college, and universities committees while also maintaining and operating the UND Space Studies Observatory . Dr. Hardersen is responsible for the operation and maintenance of three Internet-controllable optical telescopes on the site. These Internet-controllable telescopes are used in SpSt 425 and by a variety of students to conduct thesis and non-thesis research projects. Research capabilities at the UND Space Studies Observatory currently includes: small body astrometry, broadband BVRI photometry (asteroids and variable stars), and visible-wavelength stellar spectroscopy. The observatory also has the capability to support astrophotography projects via the conduct of CCD color imaging that uses RGB filters. Efforts are underway to expand solar H-alpha imaging to support regular monitoring of the Sun.
