Fun research description:

  • My research interests lie in the subfield of differential geometry called spectral geometry. I ask, “If you can hear how an object vibrates, can you say anything about the shape of the object?”
  • In 1966 mathematician Mark Kac asked a now famous question, “Can you hear the shape of a drum?” His question was answered in 1991, check out this American Math Society page to learn more.  Movies of these isospectral drums vibrating can be found at this link.
  • An applet demonstrating the vibration of a circular drum can be found at this link.

Fun yet formal research description:

I study the Laplace and Steklov spectral geometry of Riemannian orbifolds, as well as spectral graph theory. I also do discipline-based undergraduate research in quantitative biology education.
