This is the webpage of Brenda Frye, Assistant Astronomer in the Department of Astronomy/Steward Observatory at the University of Arizona. She is an observational cosmologist interested in topics relating to gravitational lensing by galaxy clusters. Cluster lensing is a powerful took, allowing 1) to measure the total mass of dark plus visible matter in the lens and 2) to probe the sources. Her research interests include doing cosmology with clusters, understanding galaxy formation and evolution, identifying high redshift galaxies, and studying the galaxy-intergalactic medium interace. This work involves analyzing high quality spectroscopy from telescopes on the ground and in space such as the Hubble Space Telescope, the Large Binocular Telescope, the Very Large Telescope, the Multiple Mirror Telescope, and ultimately the Large Synoptic Survey Telescope (LSST) and the James Webb Space Telescope (JWST). This work is leading towards a better understanding of the progress of galaxy evolution back to early cosmic times when the universe was only <500 million years old.

Brenda has undergraduate degrees in Physics and in Astronomy from the University of Arizona (UA). While at UA she completed her undergraduate thesis with Prof. Jill Bechtold (Frye et al. 1993), and was awarded the Outstanding Senior in the Department of Astronomy and the Outstanding Senior for the College of Science. Brenda did her graduate work at the University of California at Berkeley, studying with Prof. Jack Welch with the assistance of a Graduate Student Research Fellowship from the NSF. Following her Ph. D., she held an appointment as Research Scientist with the Supernova Cosmology Project at Lawrence Berkeley National Laboratory with Prof. Saul Perlmutter. She then moved on to take the NSF Astronomy and Astrophysics Postdoctoral Fellowship, and the Princeton Council on the Sciences and Technology Postdoctoral Fellowship, both Princeton University under the mentorship of Prof. Neta Bahcall. Brenda held her first faculty appointment as Lecturer in the School of Physics at Dublin City University in Ireland where she took on her first Ph. D. student (now Dr. Mairead Hurley), followed by a Tenure-track Assistant Professorship in the Department of Physics & Astronomy in the beautiful Bay Area at the University of San Franciso. She was then recruited back to her Alma Mater to take up the position of Assistant Astronomer in the Department of Astronomy/Steward Observatory. All are very welcome to browse through this site, and there are many opportunties to work with me at all levels. So if any of this research looks interesting to you please feel free to contact me.
