Darren DePoy, Professor of Astronomy and Associate Dean for Research at Texas A&M University in College Station, talks about using one of Einstein’s little-known and underappreciated method of microlensing to look for extrasolar planets around sunlike stars.  An expert on building telescope instrumentation, DePoy outlines the other methods of planet detection and a bit about the difficulties of funding huge astronomical projects such as the Giant Magellan Telescope.
