In 1991, Sasselov joined the Harvard–Smithsonian Center for Astrophysics. He has been a Harvard professor since 1998. In 2002, Sasselov and his team sighted OGLE-TR-56b, a planet in the constellation Sagittarius that was the farthest planet from the Earth discovered until then. In his search for planets, he employs novel methods that can potentially detect planets similar to Earth, and he co-operates with NASA's Kepler Mission. Sasselov's other research focuses on the interaction between radiation and matter.
