My research efforts have focused on three areas which are: . More than 200 extrasolar planets have been discovered around relatively nearby stars, primarily through the Doppler line shifts owing to the reflex motions of their host stars, and more recently through transits of some planets across the face of the host stars. ... Gravitational microlensing provides a novel technique to look for planets around lens stars, and this is the only technique currently capable of detecting Earth-mass planets. ...

... It is only a matter of time before astronomers find an Earth-sized planet orbiting a distant star. We will naturally ask whether the planet is habitable or bears life. But will we be able to tell if there are bacteria, roaming dinosaurs, or even more advanced life? ... In the past twelve years, scientists have discovered more than two hundred large planets orbiting other stars, yet finding Earth-like planets is a fascinating and substantially more technologically demanding endeavor. ...
