My research explores the origin and early evolution of the Solar System through the chemical and isotopic records preserved in meteorites and returned extraterrestrial samples. By studying ancient materials such as calcium–aluminum-rich inclusions (CAIs), chondrules, and asteroid particles, I aim to reconstruct the physical and chemical environments in which the first solids formed. These materials serve as time capsules, allowing us to probe processes that occurred over 4.5 billion years ago, including stellar nucleosynthesis, solar nebula dynamics, and the timing of planetary formation.

A central focus of my work is the use of high-precision isotopic measurements to establish a detailed chronology of early Solar System events. I investigate short-lived radionuclides and stable isotope anomalies to constrain timescales of condensation, irradiation, and mixing in the protoplanetary disk. My research also extends to lunar samples and returned materials from missions such as Hayabusa2 and Stardust, where isotopic analyses provide insights into planetary differentiation, aqueous alteration, and the distribution of volatile elements across the Solar System.

To enable these discoveries, I specialize in the development and application of advanced secondary ion mass spectrometry (SIMS) techniques. With more than two decades of experience operating, maintaining, and advancing large-radius ion microprobe and NanoSIMS instruments, I work to push the limits of spatial resolution and analytical precision for in situ measurements. These methodological innovations not only drive progress in cosmochemistry, but also have broader applications in geochemistry, geochronology, and planetary science, helping to maximize the scientific return from rare and valuable extraterrestrial samples.
