Dr. Ryan Terrien, Ph.D.

Dr. Ryan Terrien is an assistant professor in the Physics and Astronomy Department at Carleton College in Northfield, Minnesota.

Dr. Terrien works on instrumentation and techniques for high-precision Doppler spectroscopy and exoplanet detection, including the Habitable Zone Planet Finder (HPF) and NEID spectrographs. He also studies the spectroscopic characterization of low-mass stars. His current collaborations with students involve the analysis of HPF spectra of low-mass stars to better understand their chemical properties and magnetic activity.
