Research Interests

Low Temperature and Experimental General Relativity

Dr. Hamilton's research is directed toward improving the sensitivity and reliability of the Allegro resonant bar detector. He also is working toward improving the worldwide network of gravitational wave detectors as a charter member of the International Gravitational Event Collaboration (IGEC). The current active research consists of work with various techniques for optimal filtering following the path originated at LSU by Evan Mauceli and adaption of more sensitive dual squid amplifiers for a new generation of superconducting transducers. This work has involved collaborations with the Universities of Trento and Padova and with the University of Maryland.
