Reto Trappitsch is a graduate student at the University of Chicago working on presolar grains. His current research focuses on isotope anomalies due to stellar nucleosynthesis and modeling interstellar resident times of presolar grains. Furthermore he is involved in building the next generation of resonance ionization spectrometry instrument (CHILI) at the University of Chicago.
At the Field Museum's Robert A. Pritzker Center for Meteoritics and Polar Studies he works mainly in the cosmochemistry laboratory to prepare samples. Furthermore he is collaborating with Philipp R. Heck to develop new models to better constrain interstellar resident times of presolar grains.
