I am a fifth-year PhD student at UC Berkeley. My interests are in symplectic and contact geometry and interactions with low-dimensional topology. My thesis advisor is Michael Hutchings.
Here is my CV.
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.
...here 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...
...here 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...
