style="font-size:12.0pt;font-family:"Times New
Roman",serif">Pulsars are rapidly rotating neutron
stars with phenomenal rotational stability that can be used
as celestial clocks in a variety of fundamental physics
experiments. One of these experiments involves using an
array of precisely timed millisecond pulsars to detect
perturbations due to gravitational waves at much lower
frequencies than those probed by LIGO. The gravitational
waves detectable through pulsar timing will most likely
result from an ensemble of supermassive black hole
binaries. I will describe the efforts of the North American
Nanohertz Observatory for Gravitational Waves (NANOGrav), a
collaboration which monitors an array of over 70 millisecond
pulsars with the Green Bank Telescope and Arecibo
Observatory. The most recent limits on various types of
gravitational wave sources will be presented, and I will
show how these limits are already constraining models for
galaxy formation and evolution. I will then describe the
dramatic gains in sensitivity that are expected from
discoveries of millisecond pulsars, more sensitive
instrumentation, improved detection algorithms, and
international collaboration and show that detection is
possible before the end of the decade.<br>
