SheaI’m currently an Assistant Professor of Mathematics at Louisiana State University. Before that, I was a NSF Postdoctoral Fellow at Columbia University. I graduated with a Ph.D. in mathematics from the University of Pennsylvania back in May of 2009. While I was a graduate student, I worked under the supervision of John Etnyre and Herman Gluck. In case you’re interested, feel free to take a look at my Curriculum Vitae and Research Statement.

My research centers on questions in contact geometry, low-dimensional topology, knot theory and Riemannian geometry. My work addresses classification and structure problems for contact 3-manifolds as well as the Legendrian and transverse knots they contain. I am also interested in questions lying in the intersection between classical knot theory and Riemannian geometry. I study geometric invariants in magnetohydrodynamics and, specifically, higher-order analogues of helicity invariants of vector fields.

Teaching: This spring I am teaching courses on 3–manifolds and differential topology at LSU. In 2012 I received the Chauvenet Prize for expository mathematical writing at the Joint Meetings. I was awarded the prize together with my coauthors Dennis DeTurck, Herman Gluck and Daniel Pomerleano for our article The Four Vertex Theorem and its Converse.

〈Sci|State〉: 〈Sci|State〉 is Scott Baldridge’s and my attempt to create a space where world-class scientists can discuss their latest research. We’ll be keeping the discussion at the general interest level. We’ll be posting content accessible to students, teachers and researchers alike.  Please take a look and, if you like what you see, Like our Facebook page and Subscribe to our YouTube channel.
