I use experimental laboratory techniques to examine how Titan surface materials interact with each other. Specifically, I use Raman/IR/UV spectroscopy and XRD to perform kinetics studies on astrobiologically-relevant co-crystals (two unique species existing together in a fixed ratio) to characterize their formation conditions. Conducting these experiments can give a better understanding of how co-crystals form under Titan-relevant temperatures, where they may be found on Titan, and how they may affect timescales of landscape evolution.

Additionally, I am assessing the viability of membrane formation in Titan liquids by performing experiments with acrylonitrile (C2H3CN), a molecule which has theoretically been presumed to form a vesicle structure called an “azotosome.” If thermodynamic stability exists in this system, the acrylonitrile may self-assemble into the azotosome molecule.

I also enjoy studying the surfaces of other planetary bodies. I have extensive experience making geologic maps and rover traverses for the south pole of the Moon; have conducted a planet-wide survey of martian dunes; and have been a science consultant for improving autonomous elements of spacecraft for future Europa missions. Human and robotic exploration of the solar system has been a passion of mine since beginning my career in planetary science, and I look forward to more opportunities to be involved with such exploration opportunities in the future.
