My research is in
symplectic and contact topology, particularly the theory
of pseudoholomorphic curves, applications to contact manifolds,
and Symplectic Field Theory.
New 16/4/2013: we have a
2-year postdoc position
in symplectic/contact topology available at UCL, starting Autumn 2013. The application
deadline is 26 May, 2013.
I am an editorial advisor for the Proceedings / Journal /
Bulletin of the LMS, in the area of symplectic and contact topology.
For the Spring term 2013, I am organising a
learning seminar on the h-principle.
Please contact me if you're interested in participating.
Interesting seminars in the area:
Upcoming conferences of interest (listed here partly just to remind myself
where I'm planning to travel and when):
"J-holomorphic Curves in Symplectic Geometry, Topology and Dynamics",
CRM Montreal, April 30 to May 11, 2013
- Workshop on "Low dimensional topology",
Simons Center, Stony Brook, May 20-24, 2013
A Panorama of Geometry (Conference in honor of Dietmar Salamon for his 60th birthday),
ETH Zürich, June 10-14, 2013
school on Donaldson hypersurfaces, La Llagonne, June 17-21, 2013. (This is part of the larger special
Symplectic and Contact Geometry in Toulouse running from May 27 to June 28; in connection with this
I will be visiting the Université Paul Sabatier in Toulouse from June 24 to July 12.)
- Workshop and
Conference on the Topology and Invariants of Smooth 4-Manifolds,
University of Minnesota, July 31 to August 10, 2013
- LMS Short Course on
"Topology in Low Dimensions", Durham University, August 26-30, 2013
Workshop on Conservative Dynamics and Symplectic
Geometry, IMPA, Rio de Janeiro, September 2 to 6, 2013
And some conferences in the recent past.
UCL's website contains plenty of
information about our mathematics
PhD programme. Application deadlines
are around the end of January. If you're interested in applying and want to name me as a
potential supervisor, you should contact me and discuss this in advance.
- Alexandru Cioba (began October 2012)
- Marcelo Alves (began 2011; supervised jointly with Frédéric Bourgeois in Brussels)
My collaborators, present and past:
Some other people I've worked with in the past:
- Peter Albers, Universität Münster
- Barney Bramham,
Ruhr-Universität Bochum (see also IAS)
- Michael Hutchings, UC Berkeley
- Janko Latschev, Universität Hamburg
- Sam Lisi, Université de Nantes
- Patrick Massot, Université Paris Sud 11, Orsay
- Klaus Niederkrüger, Université Paul Sabatier, Toulouse
- Richard Siefring, Max-Planck-Institut, Leipzig
- Jeremy Van Horn-Morris, University of Arkansas
(see also Stanford)
In the Summer semester 2010 I organized the
Symplectic Homology Learning Seminar.
Some information about funding opportunities, events, and job postings in my field
can be found on the website of
Contact And Symplectic Topology (CAST), a
Research Networking Programme (RNP) of the European Science Foundation (ESF).
This is me, wielding my trusty water bottle to protect Imperial China
from Mongol invasion.
This is not me (in case that was unclear).
This is János, with his foot resting on
Evans, Partial Differential Equations, AMS 1991.
(Full disclosure: János used to be my cat, but has actually
been someone else's cat since I moved to Europe in 2007.
Nonetheless, I am sure he remains as fond of PDE books as he always was.)
For the Autumn 2012 term I am teaching MATH1101
(Analysis 1). Here is a link to the moodle for the
course. (If you are not enrolled in the course you will need an
"enrolment key" to access the moodle.)
In October 2012 I gave a minicourse for Master's students on "Pseudo-holomorphic
curves in Symplectic and Contact Topology" at IRMA Strasbourg.
An unexpectedly large set of lecture notes on
rational/ruled symplectic 4-manifolds and related things was
produced as a result. It is likely that they will eventually be merged with
my other lecture notes on holomorphic curves
(still in progress).
Here is some information on courses
I've taught in the past.

A Frequently Asked Question
Question: Aren't you German?
Answer: No. Don't let my name or my history of working at German
speaking universities or the blond hair
and blue eyes or the fact that you've overheard me speaking German with
my colleagues fool you. I am, in fact, not German.
An Occasionally Asked Question
Question: Where did you learn to speak English so well?
Answer: It's my native language.
A Question That Is Asked Far More Often Than It Should Be
Question: Where did you learn to speak German so well?
Answer: I don't speak German that well, it only sounds like it
if you don't listen carefully.

9/11 happened approximately midway through my graduate career in New York;
about two months before my oral exams. I've been meaning for years to
write a rambling but potent essay on this topic, and post it on the web.
I even started one on the evening of 9/11/03, but it proved rather more
rambling than potent and I abandoned the effort. It will probably never
American news and politics
The following list of links should probably be revised at some point... in
any case it reflects the fact that the five years of my Ph.D. happened to
be more or less the same years that the political situation in my homeland
started to go seriously downhill, and thus my default procrastination
activity became looking at the online front pages of
the New York Times and
Some of the organizations linked below could be characterized as, "not
always the left's best representatives, but doing more good than harm."
And here are some other sources for news and related stuff.
- C-Span: probably the most
comprehensive source available for political news and archived video
- FAIR: Fairness & Accuracy in
Reporting. A media watchdog group -- far from perfect and certainly
not unbiased, but still a rich source of interesting and often disturbing
information, all of it true.
- The Brian Lehrer
show archive: at some point after I almost recovered from the shock of
WNYC in New York killing most of their classical music programming (almost;
I'll never fully recover), I
discovered that their daily call-in show host, Brian Lehrer, is easily the
best journalist in New York. WNYC's website has
extensive archives of his program.
- On The Media: another public
radio program that I think highly of
- Air America Radio: you
know, that "liberal talk radio network" that people have been theorizing
about for years. It exists now, and while I
wouldn't say that all their programs are uniformly wonderful, it's good to
have someone counteracting the propaganda from the other side.
- Talking Points Memo:
Josh Marshall's political blog. It's written from a center-left
perspective, and often pays attention to little-known stories that would
infuriate most people if only the media made the effort to pay
- AndrewSullivan.com: my
favorite summary of Sullivan's viewpoint comes from an e-mail he posted
from one of his readers, who was surprised to read that he characterized
himself as a conservative; "I just thought you were a liberal with a
handful of wrongheaded opinions."
Ashcroft sings. Yes, he does. If you need further explanation, (and
what sane person wouldn't?), see this
article in The Guardian
posting about gay marriage, from Adam Felbers' blog,
And let me just say, since there seem to be some people in the world who
don't understand this, it's satire!
- The Human Rights Campaign: gay
marriage. In 50 years it will seem perfectly normal, but right now it's
driving the United States out of its collective mind. Gets harder and
harder to be a closeted bigot these days.
