Dr. Sarah J. Greenwald's home page

I am an associate professor in the Department of Mathematics and a Women's Studies core faculty member at Appalachian State University in the northwestern mountains of North Carolina, and a winner of a 2005 MAA Alder Award for distinguished teaching. I received my Ph.D. from the Department of Mathematics at the University of Pennsylvania in Philadelphia, and my B.S. in math from the Department of Mathematics at Union College in Schenectady, NY. I was born in Charlotte, NC, but grew up in Buffalo, NY. For more information, see my academic cv and recent talks and a short biography.

My mathematical ancestors from The Mathematics Genealogy Project

I am the project coordinator of the Bialobrzegi ShtetLink and the Book of Remembrance of the Community of Bialobrzeg for JewishGen: The Home of Jewish Genealogy. The projects strive to research and preserve information about small Jewish communities that were destroyed in World War II. My great-grandmother lived here (it was the Russian empire back then!) in the late 1800s.
