Research interests

• Cosmochemistry
• Nuclear chemistry
• Cosmic ray exposure histories of extraterrestrial materials (meteorites, lunar samples, and micrometeorites) and terrestrial materials (surface rocks, ice cores, and atmosphere), using cosmogenic nuclides such as 53Mn, 10Be, 26Al, 36Cl, and 41Ca; secular variation of solar and galactic cosmic rays.
