  • CURRENT RESEARCH

    My research interests are primarily in low-frequency gravitational wave astrophysics and data analysis, but I'm also interested in various aspects of cosmology, binary star evolution, and gravitational dynamics in exoplanetary systems.

    Here are a few things that I am currently working on:

    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. Considering the self-gravity influence on gravitational wave emission from isolated magnetars (with Purdue).

    3. Characterizing the Integrated Sachs Wolfe effect on gravitational wave signals and the resulting impact in science analysis (with Laguna and Yunes).

    4. Development of gravitational wave analysis techniques for detecting eccentric binary systems (with Hellings).

    5. Simulation of Roche Lobe overflow in compact (gravitational wave emitting) binary systems (with Knight).

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

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


    RECENTLY COMPLETED

    1. Reexamination of the overlap reduction function that characterizes using multiple gravitational wave observatories to detect cosmological backgrounds (paper submitted to Physical Review D, with Romano and Finn.

    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. Paper describing development of university based high altitude balloon systems for student access to near space (paper submitted to American Journal of Physics, with Hiscock and Armstrong).
