Dr. Sarah J. Greenwald's home page
I am a professor in the Department of Mathematics and faculty affiliate of Gender, Women's and Sexuality Studies at Appalachian State University. Investigating connections between mathematics and society, I have won several awards for teaching, scholarship and service, most recently as an AWM Fellow. Some others include an MAA Alder Award, a Wayne D. Duncan Award, and College of Arts and Sciences Outstanding Teacher of the Year. I earned my PhD from the University of Pennsylvania and my BS in mathematics from Union College. For more information, see my academic cv and recent talks and a biography.

    Other Interests

  • My mathematical ancestors from The Mathematics Genealogy Project
  • In my spare time I like to travel, hike and conduct genealogy research (I also enjoy popular culture, as you can probably tell from some of my scholarly interests). In addition to my own personal genealogy, I like to give back to the broader community and it is based on this that I am a faculty affiliate of the Center for Judaic, Holocaust & Peace Studies. I am the project coordinator of the Bialobrzegi KehilaLinks and the Book of Remembrance of the Community of Bialobrzeg among others for JewishGen: The Home of Jewish Genealogy. These projects strive to research and preserve information about small Jewish communities that were destroyed in World War II. My great-grandparents lived here (it was the Russian empire back then!) in the late 1800s. Some of what I really like about mathematics is also what I enjoy about genealogy - the sense of exploration, discovery and aha moments that come with lots of patience and effort.
  • I am married to Joel Landsberg. We both happen to be on IMDb: Joel and me. My Erdos Bacon number is 6-7 or infinity, depending on what/how you count. Joel won 2023 Chief's Award for the Wilkes Rescue Squad and was Wilkes Rescue Squad EMT of the year in 2021.
