| Davis Postdoctoral Fellow, Johns Hopkins University
| 9/99-7/01
|
|
Developed a comprehensive package for numerical integration of
hierarchical N-body systems using symplectic methods with
Doug Hamilton. Expanded a subroutine library for tracing
arbitrary geodesics in the Kerr metric, and examined the visual
appearance of black hole accretion disks.

Investigated the stability properties of symplectic integrators
applied to nearly-Keplerian problems in collaboration with Matt
Holman; completed additional work on the dynamics of black holes
in galactic nuclei.

Published an undergraduate senior thesis on the possibility of
limiting the cosmological density of compact dark matter objects
through microlensing effects on distant supernovae
(advisor: Bohdan Paczynski).

Worked with James Cordes on the feasibility of using interstellar
scintillation data to constrain the size of pulsar magnetospheres,
under the auspices of the NSF Research Experience for Undergraduates
program.

| Junior Term Projects, Princeton University
| 9/88-5/89
|
|
Completed two undergraduate term projects; one analyzed CCD
photometry of the gravitational lens Q2237+0305 to test for
microlensing-induced brightness variations among the images
(advisor: Ed Turner); the other studied the consequences of a
non-zero Λ cosmological model for the redshift distribution
of quasars and the strength of the UV background
(advisor: Jerry Ostriker).
