Dante Lauretta's research interests focus on the origin and chemical evolution of the solar system. His main focus is the formation and alteration of minerals in the solar nebula and on meteorite parent asteroids. He is also working on the application of inductively coupled plasma-mass spectrometry to geologic studies. In addition, he is studying the extent of Hg isotopic fractionation in natural systems. This project represents a potentially new stable isotope system with applications in meteoritics, geology, biogeochemistry, and environmental studies.
