Cosmochemist · Decoding Galactic chemical history through meteoritic stardust

prof_pic.jpg

I am a Senior Research Scientist at the Institute for Astrophysical Research, Boston University. My research uses in situ isotope measurements of microscopic stardust grains — preserved in primitive meteorites for billions of years — to test theoretical models of stellar nucleosynthesis and trace the chemical evolution of our Galaxy. I received my Ph.D. in Cosmochemistry from the University of Chicago in 2014, and was previously a Research Assistant Professor at Washington University in St. Louis (2018–2022) and a Postdoctoral Associate at Carnegie EPL (2014–2017).
