Meenakshi Wadhwa studies primitive meteorite groups (including enstatite chondrites, eucrites, and mesosiderites) as well as some of the youngest known meteorites (e.g., the SNC or "martian" meteorites). Her current research on these widely diverse objects seeks to decipher the processes involved in their formation using trace element distributions in their minerals, and to determine the time scales of their formation using long-lived (Samarium-Neodymium and Rubidium-Strontium) and short-lived (Manganese-Chromium) chronometers, in order to better understand meteorite formation events and their chronology in the solar system.
