Sarah Salviander, PhD, is a research scientist in the field of astrophysics and a visiting professor of physics. Her research interests are nature’s most extreme objects: quasars and supermassive black holes. Dr. Salviander grew up in the wild Crown Lands of Northern British Columbia, Canada, in a family of American expats. She developed a strong interest in studying space at a young age, but once she realized she wasn’t cut out for life as an astronaut, she decided to explore the universe through science. Dr. Salviander received her Ph.D. in astrophysics from the University of Texas at Austin, and has numerous journal and conference publications to her name. She is the author of the Castalia House homeschool curriculum ASTRONOMY AND ASTROPHYSICS.
