Dr. Melosh's principal research interests are the many ramifications of impact cratering, planetary tectonics, and the physics of earthquakes and landslides.

His recent research includes studies of the giant impact origin of the moon, the K/T impact that extinguished the dinosaurs and the ejection of rocks from their parent bodies.

He is also active in astrobiological studies that relate chiefly to the exchange of microorganisms between the terrestrial planets.
