Office: 1039 Evans.

I am a fifth-year PhD student at UC Berkeley. My interests are in symplectic and contact geometry and interactions with low-dimensional topology, specifically in using Floer homologies to understand Reeb dynamics on contact manifolds. My thesis advisor is Michael Hutchings.

Here is my CV.

Research and Papers

Pattern avoidance in poset permutations, arXiv: 1208.5718, co written with Sam Hopkins. Order July 2016, Volume 33, Issue 2, pp 299–310. We extend the concept of permutation pattern avoidance to partially ordered sets.

And... is an animation of a torus turning inside out. I thought this was pretty cool when I was an undergrad and it's helped me understand a bunch of different parts of low-dimensional topology: open book decompositions, Heegaard splittings, the Hopf bundle...

Valid XHTML 1.0 Transitional is the image of the segment with r_1 between .9 and 1 and theta_1 = theta_2 = 0 under the Reeb flow of the standard contact form on the three-sphere (in black) along with the zero page of the open book decomposition p(r_1,theta_1,r_2,theta_2) = theta_1 + theta_2 (in yellow); this picture is helpful when computing rotation numbers and Conley-Zehnder indices for homology computations...
