I am a
sixth year Ph.D.
student in the Harvard University Department
of Astronomy. I received my B.A in Physics & Astrophysics from
UC Berkeley in 2001, and an A.M. in Astronomy
from Harvard in 2006. I am working
on my Ph.D. thesis project with Professor
Robert Kirshner on Infrared
Light Curves of Type Ia Supernovae (expected graduation 2010). Type Ia Supernovae
can be used as standardizable
candles for cosmology
to measure the expansion
history of the universe and constrain the mysterious dark energy thought to be causing the acceleration of cosmic expansion. The supernova aspect of
the project uses infrared data obtained with the fully robotic 1.3 meter Peters
Automated Infrared Imaging Telescope (PAIRITEL)
at the Fred
Lawrence Whipple Observatory on Mount Hopkins, Arizona (P.I. Professor
Joshua Bloom, UC Berkeley).
My previous work with Professor
Ramesh Narayan and Professor
Joshua Bloom focused on testing the potential
applications of Gamma-Ray Bursts (GRBs) for cosmology by studying
GRB spectra and energetics. My work has been supported
in part by
a National Science
Foundation Graduate Research Fellowship and
a NASA Graduate
Student Research Program Fellowship, where I collaborated
with researchers at the NASA
Goddard Space Flight Center in Greenbelt, Maryland, including Dr.
Neil Gehrels, the Principal Investigator of the NASA
Swift Satellite, a space experiment that studies both GRBs and
supernovae.
