Introduction

I am an isotope cosmochemist and laboratory astrophysicist, investigating the chemistry on rocky and icy surfaces of asteroids and comets to understand how they originated and processes prevalent in small planetary bodies. My team studies the fine particulate dust (< 100 micrometer) on and from small solar system bodies.

I am an Associate Professor and Associate Director for Community Outreach in the School of Earth and Space Exploration (SESE) at Arizona State University (ASU) in Tempe. I oversee the NanoSIMS (Secondary Ion Mass Spectrometer) funded by the National Science Foundation and ASU. I use the NanoSIMS to decipher the isotopic fingerprinting between the gas and solid states.

My expertise is in using Nano-scale Secondary Ion Mass Spectrometry (NanoSIMS) to acquire isotopic data at small spatial scales (<100nm) and greater precision (sub-permil precision for light and volatile elements (H, C, N, O, Li, B, S). I use the numerous analytical techniques in conjunction with the NanoSIMS to probe extraterrestrial materials and planetary analogs and understand cosmochemical histories of small planetary bodies and planets.

I am a handling editor in the Advances in Geochemistry and Cosmochemistry  (AGC) journal, which is a community-led diamond open access journal. It aims to publish innovative and globally relevant articles in Geochemistry and Cosmochemistry. You can submit your manuscripts to the journal now (website).
