Gladman is best known for his work in dynamical astronomy in the Solar System. He has studied the transport of meteorites between planets, the delivery of meteoroids from the main asteroid belt, and the possibility of the transport of life via this mechanism, known as panspermia. He also studies planet formation, especially the puzzle of how the giant planets came to be. Panspermia is the hypothesis that the seeds of life are in the Universe, that they may have delivered life to Earth, and that they may deliver or have delivered life to other habitable bodies; also the process of such delivery. ...
