My research is in
symplectic and contact topology, particularly the theory
of pseudoholomorphic curves, applications to contact manifolds,
and Symplectic Field Theory.
I am an editorial advisor for the Proceedings / Journal /
Bulletin of the LMS, in the area of symplectic and contact topology.
I currently organise the UCL Symplectic Working Group Seminar.
In the Spring term 2013, I also organised a
learning seminar on the h-principle.
Interesting seminars in the area:
Here is a list of upcoming conferences and workshops that I think
It used to be a list of events that I was personally planning to attend, but
then I found out that some people are actually using it to find out what's
going on, so I've added more events that I won't necessarily be attending.
(Thus if your main goal is to stalk me, this list will be only partially helpful.)
VIII Workshop on Symplectic Geometry, Contact Geometry, and Interactions,
Instituto Superior Técnico, Lisbon, January 30 to February 1, 2014
Warwick - Seoul
National University Symplectic Geometry Workshop, University of Warwick, February 18 - 19, 2014
- Workshop on Moduli Spaces of Pseudo-holomorphic Curves I,
Simons Center, Stony Brook, March 17 - 21, 2014. This workshop and its sequel listed below are both part of the Simons Center's
program Moduli spaces of pseudo-holomorphic curves and their applications to symplectic topology, running from
January 2 to June 30, 2014. I will be in residence at the Simons Center from June 16 to 27 as part of this program,
which also includes informal workshops on polyfolds (May 5-9) and on the foundations
of contact homology (June 16-20).

And some conferences in the recent past.
If you are interested in doing a PhD under my supervision, you should apply to
the London School of Geometry and Number Theory,
a new EPSRC-funded PhD programme run jointly by UCL, King's College and Imperial College London.
If you are not a citizen of the European Union, then you may need to make a
separate application to UCL for funding; more information on this may be found
on the UCL maths
PhD programme website.

- Marcelo Alves (began 2011; supervised jointly with Frédéric Bourgeois, formerly
of the UL Brussels)

In the Summer semester 2010 I organized the
Symplectic Homology Learning Seminar.

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.)
Since my arrival at UCL in 2011, I have

"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.
Towers of Light (as seen from the Staten Island
Ferry, 9/11/04; photo by MPW)
9/11 happened approximately midway through my graduate career in New York;
about two months before my oral qualifying 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
