Current activity
In the Spring and Fall semesters of 2014, I am teaching a lecture
course in firstyear linear algebra. Please visit the class
website for further information.
In Spring 2014, I am also teaching a graduate course on knots and Floer
homology
(officially called Algebraic Topology). There is a website
for that class as well.
Professional
Information
I am a researcher and instructor of mathematics. I live
with my wife
Makiko
and our two daughters.
I am fortunate to have spent time at the following great
institutions:
For more detailed information, please see my CV.
Research
My main research interests are in lowdimensional
geometric topology,
in particular in contact 3manifolds and
Legendrian knots (and their Floer homologies), as well as in
classical knot invariants such as the Homfly polynomial. Recently I
started doing work on graphs and hypergraphs, too. Through
combinatorics, I found interesting new connections between knot
polynomials and Floer homology.
Publications
 Part of my undergraduate
thesis
(Stable maps of surfaces into the
plane) was published at Topology
and its Applications.
 With my undergraduate advisor András Szűcs,
we
coauthored another
paper (On double points of
immersed surfaces)
in the same journal.
 My doctoral
dissertation
(Contact homology and one parameter
families of Legendrian knots) was published at Geometry and Topology.
 A followup paper
(Braidpositive Legendrian links)
appeared in the International
Mathematics Research Notices.
 This manuscript
(Maximal ThurstonBennequin number of
+adequate links) was published in the Proceedings of the American
Mathematical Society.
 This article
(Rulings of Legendrian knots as
spanning
surfaces) appeared in the Pacific
Journal of Mathematics.
 This paper
(Isotopies of Legendrian 1knots and
Legendrian 2tori), joint with Tobias Ekholm,
was published in the Journal
of Symplectic
Geometry.
 The manuscript
Meridian
twisting of closed braids and the Homfly polynomial appeared
in the Mathematical
Proceedings of the Cambridge Philosophical Society. Here are the
slides of a talk
I gave on the subject.
 The paper Inner products on the Hecke algebra of the
braid group was published in Topology
and its Applications.
 My first paper
on combinatorics, A version of
Tutte's polynomial for hypergraphs, appeared in Advances
in Mathematics. I gave several versions of
this talk
on the results in it.
 Our joint paper with András
Juhász and Jake
Rasmussen, Sutured Floer
homology and hypergraphs, was published at Mathematical
Research Letters. It is summarized in these slides.
 With Tobias Ekholm and Ko Honda, we wrote a paper on Legendrian knots and
exact Lagrangian cobordisms that is due to appear in the Journal
of the European Mathematical
Society. I discussed its contents in this talk.
