CURRENT RESEARCH

1. Considering what information about the structure of the galaxy is embedded in the confusion background of low frequency G-waves (with Taylor and Benacquista).

2. Examining what astrophysical information can be extracted from the gravitational wave ringdown phase after the coalesence of two supermassive (e.g. 10^8 + 10^8 Msun) black holes (with Shoemaker).

3. Considering influence of close encounters between a LISA spacecraft and meteoric particulates in the solar system (with Purdue).

4. Full simulation of the "zero signal solution" using LISA simulators, like Vallisneri and Armstrong's "Synthetic LISA" (with Tinto, Vallisneri and Drasco).

5. Extending, enhancing and applying the gCLEAN algorithm (for subtracting binary gravitational wave sources from LISA data streams) to mock LISA data. (with Cornish, and with Gair).

6. Other interests include cosmological parameters, galactic dark matter (MACHOs), primordial black holes, and sources of gravitational radiation.

RECENTLY COMPLETED (past year)

1. Extensive review paper of the LISA observatory: design, interferometry, and astrophysics (paper to appear in Proceedings of the 33rd SLAC Summer Institute).

2. Estimated the contribution to the gravitational wave confusion foreground from mass transferring binaries in the galaxy (paper submitted to Astrophysical Journal, with Benacquista, Belczynski and Ruiter).

3. Estimated the effect of space weather on a LISA spacecraft from existing solar data from the past solar cycle (paper submitted to Classical and Quantum Gravity, with Zaleski).

4. Two papers on introducing gravitational wave astrophysics into physics and astronomy classes (papers accepted in The Physics Teacher, with Rubbo, Zaleski and Larson).

5. Computed gravitational radiation evolution and lifetime for small particles in high eccentricity orbits around Schwarzschild black holes, improving the classic estimate of Peters for Keplerian orbits (paper accepted in Astrophysical Journal, with Gair and Kennefick).
