## About me

I am currently a postdoc in mathematics at Dartmouth College. My research interests lie in the field of low-dimensional topology. In particular, I am interested in knot theory in dimensions 3 and 4.

Before coming to Dartmouth, I completed my PhD in mathematics at Indiana University advised by Charles Livingston.
