Summary
I do research in mathematical probability.
A central theme is the study of large finite random structures,
obtaining asymptotic behavior as the size tends to infinity
via consideration of some suitable infinite random structure.
Research topics
The topics are listed on the left; here is a guided tour.
My main current (2011) research focus is on Scale-invariant random spatial networks
and on FMIE processes.
I am working with post-docs
Justin Salez and
Mykhaylo Shkolnikov.
Over 2007-10 I was focussing on
discrete spatial networks
and on
flows through random networks,
partly with my recent student
Shankar Bhamidi
and current student
Jason Lenderman. Various results remain to be written up.
During 2005-08 I was involved with two very different projects. First,
Combinatorial optimization over random data
and its scaling exponents with post-doc Charles Bordenave and Marc Lelarge.
And finally appearing in 2011 is the third and final paper in
a project
stochastic models for phylogenetic trees
with former student Lea Popovic
and former post-doc Maxim Krikun.
During 2000-04 my main focus was on the overlapping topics of
and I remain interested in rigorous formalizations of the cavity method from
statistical physics.
Also a series of papers with Gregory Miermont and Jim Pitman on
Nonuniform random mappings, ICRTs and Levy-type
excursions,
which partially continue my 1990s work on the
continuum random tree.

electronic versions of papers since 1997.

slides from seminar and conference talks.
