Autonomous Science Agent Frameworks
Analysis
We are developing a modular framework for an autonomous onboard science 'agent' that can perform sample analysis and use a combination of a priori assumptions and artificial intelligence to update science priorities, communicate findings, prioritize future science data collection, and carry out these actions in the absence of ground-in-the-loop interaction. This technology is specifically useful for planetary missions in which communication is difficult or episodic.
Mass Spectrometry Science Autonomy for Ocean Worlds
Astrochemistry
My group is a new cooperative network spanning mass spectrometer instrument developers, ocean worlds laboratory analog experimentalists, and machine learning experts in an effort toward developing science autonomy for ocean worlds missions. We are working to: 1) develop flight instruments that can function autonomously in order to achieve established science goals and 2) develop consistent and streamlined methods for interpreting data from flight mass spectrometers.
Earth and Planetary Atmospheric Predictions Using Machine Learning
Atmospheric Measurement
We are developing machine learning models to predict in situ atmospheric isotopes using spacecraft data.
Isotopic Fractionation on Ocean Worlds
Astrochemistry
We are working toward developing predictive models for abiotic isotopic fractionation on, and analysis of mass spectra from, Ocean Worlds targets by conducting laboratory experiments of analog conditions.
Isotopic Biosignatures on Ocean Worlds
Astrobiology
This project focuses on the viability of detecting isotopic biosignatures of life on Ocean Worlds through experimental laboratory analogs.
Habitability of Ocean Worlds
Astrobiology
Evaluation of habitability of ocean worlds environments through analysis of experimental laboratory analogs and computational modeling.
Ecosystem Effects of Oceanic Dead Zones and Biotic Recovery
Ecosystem function
Study of widespread development of 'dead zones' - low oxygen oceanic zones typically positioned near continents - in Earth's past, with particular focus on the climatic and oceanographic conditions that promote dead zones, and well as recovery from these events. Research is conducted through a combination of fieldwork and laboratory analysis.
