Much of my recent research has involved the development of liquid mirror technology. The technology allows large-aperture zenith-pointing telescopes to be built for a fraction of the cost of a conventional telescope comparable power. This has so far resulted in the construction of two 2.7-m lidar telescopes, a 3-m NODO telescope used by NASA to study space debris, and the 6-m LZT.

There are presently two projects underway to build liquid-mirror telescopes at excellent astronomical sites in Chile. These are the 4-m International Liquid-Mirror Telescope project and the 8-m ALPACA project. In addition, liquid mirror technology has the potential to enable the construction of powerful telescopes on the Moon.
