Bio

2017-2023– Graduate Student, Department of Earth, Atmospheric and Planetary Sciences, MIT
2007-2011– Sc.B, Geological Sciences, Brown University, Providence, Rhode Island

I received an Sc.B. in Geological Sciences from Brown University in 2011 where I wrote my  thesis on the evolution of the El Niño Southern Oscillation (ENSO) through the Holocene using alkenone lipid biomarkers. After, I worked as a research assistant at Brown and later in the Lamont-Doherty Core Repository at Columbia University until 2014. In 2015, I moved to MIT and served as research staff for the development team of a metagenomics-based Mars life detection instrument called SETG, The Search for Extra-terrestrial Genomes. In 2017, I began my graduate studies at MIT, for which I was co-advised by Roger Summons and Maria Zuber.

Research

My research involves the search for life on Mars, biomarker preservation, and the origins of life on Earth.

While the role of late diagenesis alteration and preservation of biomarkers (e.g., lipids) is well understood, few studies have focused on the diversity of early diagenetic processes, which dictate preservation depending on environmental setting. In order to better understand the relationship between depositional environment and sedimentary biological processes, I analyze the lipid suites of thermally immature fish concretions from around the world. The partially decomposed fish contain a wide range of lipids from eukaryotes, bacteria, and archaea. These molecular fossils provide a unique opportunity to probe the diagenetic continuum or the window into the biological-geological (e.g., sterols to steranes; hopanols to hopanes) transition and preservation of biomarkers.
