NICMOS Observations of the GG Tau Circumbinary Disk
Hubble Space Telescope NICMOS images of the circumbinary disk
surrounding the pre-main sequence star, GG Tau A are analyzed.
The spatially resolved proto-planetary disk scatters ~1.5% of the
stellar flux in all three filters, resulting in neutral colors.
Monte Carlo scattering simulations of the disk show that the basic
properties of the disk can be roughly recreated using ISM-like
dust particles and does not require the presence of either circumstellar
disk reddening or large ('grey') dust particles, as had been previously
suggested.
Results from this work have been presented at the January 2000
AAS meeting, Atlanta, GA and at the IAU 200 meeting on Binary
stars in Potsdam, Germany in April 2000. Submitted to ApJ, February 2002.

Multiplicity Survey of the L1641N star forming region in Orion
Reduced and analyzed 2.2 micron speckle interferometry data on young
stars in the L1641N cloud in Orion, taken with the NIRC camera
on the Keck 10-m telescope. Results from previous multiplicity surveys
of open clusters suggest that Orion should have a multiplicity
between that of the solar neighborhood and the nearby star forming
regions of Taurus and Ophiuchus. Approximately 20% of the sample in
L1641N have been observed so far, with an observed multiplicity
consistent with that of the solar neighborhood. More observations
are planned to increase the statistical significance of this work.
High Resolution Proper Motion Study of the central parsec of
the Galactic Center
Assisted the 2.2 micron speckle observations of the central 5 arcsecs
of the Galactic Center, using NIRC on the Keck 10-m telescope. Three
epochs of observations were reduced and combined using the Shift-And-Add
speckle technique, allowing diffraction-limited images. Two known
water masers in the region were observed to register the near-infrared
speckle data with the published radio observations from which
the position of Sgr A*, the radio source believed to be a
supermassive black hole, was determined.

The search for a Luminosity-Period Relation for M Supergiants
Observed 8 SRVc Supergiants (Semi-Red Variables, type c)
in the h and chi Persei double cluster, in the V,R and I
bands using Leicester's 24'' telescope, as part of a long term
monitoring program on these objects to investigate a possible
Period-Luminosity relation for these long period (P~800 days)
objects. Wrote a FORTRAN program to handle the data input/output
and analysis.
Teaching Assistant
Taught discussion sections for introductory Astronomy courses
at UCLA. Responsible for explaining lecture material, preparing
and grading exams and providing individual instruction. Also
hosted the UCLA Observatory open house and held Planetarium
shows to both students and members of the public.
Instructor at the Young Engineering and Science Scholars (YESS) Program, Caltech
Supervisor: Dr. Paul A. Robinson, Jr.
Responsible for creating and teaching an engineering curriculum
for the YESS program held at Caltech, which is designed to provide
an opportunity for bright high school students from low-income
neighborhoods to experience science and engineering research.
Highlighting problem solving skills, teamwork and environmental
awareness, the students in my class successfully designed and
built an air quality tester that could be flown from a weather
balloon.
