Welcome!

My primary area of interest is in astrobiology, focusing on modeling potential biospheres in order to aid in their detection. In collaboration with Professor Regis Ferriere and colleagues, I am working on developing mathematical models that simulate and assess the possible conditions of potential subsurface biospheres on icy moons. I am also interested in modeling the origin and co-evolution of potential biospheres with their planetary environments.

These models are comprehensive, incorporating simulations of cell metabolism, ecosystem dynamics, geochemistry, plume composition, and more. A key component of our approach is the application of a Bayesian statistical framework, which facilitates the estimation of probabilities for alternate hypotheses. Importantly, this Bayesian approach enables us to analyze forthcoming data from the NASA Europa Clipper and ESA JUICE missions, helping us ascertain whether the evidence suggests abiotic processes or potential signs of life. This will enrich our understanding of Europa and other icy moons, informing future exploration and the search for extraterrestrial life.

As a NASA Space Grant fellow and an instructor for SkySchool at the University of Arizona, I enjoy bringing the scientific insights from my research to audiences of all ages. By leveraging public outreach, I hope to foster a broader appreciation for mathematical models, astrobiology, and space exploration with the goal of inspiring the next generation of scientists to further uncover the mysteries of the cosmos.
