What He Studies

Exoplanetary science, which is devoted to the discovery and characterization of planets around other stars, and understanding the formation, histories, and properties of these planets—with the ultimate goal of finding planets that could harbor recognizable life, and to detect the presence of that life (an effort that falls under the banner of astrobiology).
