I am an
EPSRC Postdoctoral Fellow
in the Department of Pure Mathematics and Mathematical
University of Cambridge.
This allows me to study fun questions in
low dimensional topology and geometry.
I am particularly interested in
relationships between Heegaard Floer theory
and various non-gauge-theoretic
structures in 3 and 4 dimensions,
such as left-invariant fundamental group orders,
taut foliations, tight contact structures,
and complex surface singularities.
My original training was in mirror symmetry and string theory,
and I am still a fan of both.
Due to an unusual career trajectory, I am an old human but a young postdoc.
After double-majoring in mathematics and physics
and applying to graduate schools in both fields, I started September 2000
as a PhD student in
theoretical physics at Stanford,
but with a deferred position as a PhD student in
pure mathematics at Harvard.
I proceeded to spend 2 years in physics departments (one at Stanford
and one as a visitor in the string theory group at Rutgers) and 2 years at
Harvard math before falling victim
to a colossally stupid burn accident, which required two years of recovery
before I was cognitively able to do math again.
Thus, it was not until 2006 that
a Park City Mathematics Institute
summer school seduced me, against my best intentions,
into becoming a low dimensional topologist and
studying with Zoltán Szabó at
I graduated from Harvard 3 years later in 2009, minus several months
with hyperemesis and a year of full-time maternity leave.
After graduation I devoted the next 5 years to full-time motherhood of
1.6 kids, amortized.
I started my first postdoc in October 2014 at Cambridge
and am now on an EPSRC Fellowship.
