Gwen Rudie studies the chemical and physical properties of very distant, so-called high-redshift galaxies and their surrounding circumgalactic medium. She is primarily an observational astronomer working on the analysis and interpretation of high-resolution spectroscopy of high-redshift Quasi Stellar Objects and low to medium-resolution near-infrared and optical spectroscopy of high-redshift galaxies. She is interested in understanding the intergalactic medium as a tool for understanding galaxy evolution and the physical properties of very distant galaxies such as the composition of stars and their star formation rates
Rudie received her AB from Dartmouth College and her Ph D from Caltech. She was the Carnegie Princeton Postdoctoral Fellow before becoming a staff astronomer.
