पीयूष श्रीवास्तव
In August 2014, I submitted my
dissertation at UC Berkeley.
Since September 2014, I am a postdoctoral scholar at
the Center
for the Mathematics of Information at Caltech.
I am broadly interested in randomized algorithms (and
especially in connections between phase transitions and
sampling). My research advisor at UC Berkeley
was Alistair
Sinclair.
Before coming to Berkeley, I did my undergraduate studies
in computer science
at IIT Kanpur.

Spatial mixing and the connective constant: Tight
bounds.
 Extended abstract to appear in the proceedings of the
ACMSIAM Symposium on Discrete Algorithms (SODA), 2015.
 The results of this paper subsume and unify the results
of the preliminary paper below, and also add new
results for the monomerdimer model. For details, see Part 1
(especially, Chapter 4) of
my dissertation.
