Biography

Dr. Guillermo Gonzalez received his B.S. degrees in Astronomy and Physics from the University of Arizona (1987), then his M.S. and Ph.D. degrees in Astronomy from the University of Washington (1990 and 1993, respectively) conducting photometric and spectroscopic analyses of W Virginis and post-AGB stars. Then, he was at the University of Texas at Austin as a post-doc for three years. While there, he frequently observed at the McDonald Observatory in west Texas, where he obtained high-resolution spectra of stars. He discovered that stars are more likely to host giant planets if they are metal-rich. He did a second post-doc at the University of Washington, where he continued to work on spectroscopy of evolved stars and stars hosting Doppler-detected planets and developed the Galactic Habitable Zone concept. He then joined the Astronomy and Physics Department at Iowa State University. There he continued working on astrobiology topics and evolved stars, taught astronomy courses, and served as the director of the Fick Observatory. He went on to do similar work at Grove City College for five years, followed by Ball State University for six years, where he taught astronomy and physics courses. He joined UAH in 2019.

Dr. Gonzalez's interests include astrobiology, quantitative stellar spectroscopy, stellar photometric variability, and ancient astronomical observations.

He has published two books over 80 peer-reviewed papers.
