Richard
Stanley
is
the
world's
leader
in
algebraic
and
enumerative
combinatorics.
He
has
written
over
140
scientific
papers,
with
more
than
40
co-authors,
and
has
supervised
44
PhD
students.
His
two
volume
book
"Enumerative
Combinatorics"
(1986
and
1999)
is
the
definitive
work
on
the
subject,
and
has
had
an
immense
influence
on
today's
combinatorialists.
His
strong
vision
of
the
interaction
between
algebra
and
combinatorics
has
been
central
to
much
of
recent
developments
in
algebraic
combinatorics.
He
has
done
this
through
his
superb
ability
to
create
new
topics
for
study
in
their
own
right,
and
indeed
he
has
pioneered
the
applications
of
commutative
algebra,
algebraic
geometry,
algebraic
topology,
Lie
algebra,
and
group
representations
to
combinatorial
problems.
This
has
led
to
mathematical
theorems
of
fundamental
importance,
and
because
of
his
uncanny
insight,
to
deep
conjectures
in
these
areas.
