I am a professor in the Department of Mathematics and a Gender, Women's and Sexuality 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, the 2010 Appalachian State University Wayne D. Duncan Award for Excellence in Teaching in General Education, and the 2011 College of Arts and Sciences Outstanding Teacher of the Year. In 2010 I was also inducted into the Appalachian State University College of Arts and Sciences Academy of Outstanding Teachers. I co-edited the 3-volume Encyclopedia of Mathematics & Society, which was named a "Best Reference 2011" by Library Journal. 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.

    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 ShtetLink 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-grandmother 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.
