General interests are in the use of precision distance measurements in astrophysics, gravitational physics and planetary studies. The main current activity is studies with R. T. Stebbins, D. Hils, J. Faller and many others on a proposed gravitational wave mission called the Laser Interferometer Space Antenna (LISA). LISA is a candidate for a joint mission of the European Space Agency and NASA, with a possible launch date of 2010. It involves laser heterodyne measurements of distance changes over 5 million km baselines between 3 separate spacecraft located about 50 million km behind the Earth in orbit around the Sun. The principal objective of the mission is the detection and detailed study of signals from sources involving massive black holes at cosmological distances. Such signals would also provide nearly ideal tests of general relativity under extremely non-Newtonian conditions. In addition, resolved signals from thousands of white dwarf binaries throughout our galaxy will be measured.
