            experimental gravity group carries out precision gravity experiments 
            and develops highly sensitive gravity sensors. Our transducer is now 
            reading out signals from Allegro at Louisiana State University, the 
            only remaining resonant-mass gravitational-wave detector in the US. 
            Our future experimentation includes the development of a gradiometer 
            that will have an impact upon the fields of geophysics, resources 
            exploration and navigation. In addition, we are collecting and analyzing data from the Laser
Interferometer Gravitational-wave Observatory (LIGO) as part of the
LIGO Scientific Collaboration. |
