The Uzboi-Landon-Morava (ULM) system is a beautiful, ~8k km long outflow channel east of Valles Marineris. I'm interested in the distribution of hydrated minerals (especially Fe/Mg- and Al-bearing clays) throughout the system and what this might tell us about their potential sources and sinks.

Some hydrated minerals will readily exchange water with the atmosphere, while others tend to behave as sinks. I'm interested in how the hydration state of minerals changes under Mars-like conditions, and to what extent we can observe changes using VNIR spectroscopy.

Biofilms are robust collectives of adhereant cells that may leave behind trace biomarkers on the surfaces they attach to. Certain minerals may be more advantageous for biofilms as a result of their redox potential. I incubated cells on astrobiologically-relevant minerals to investigate the extent to which microbes may preferentially adhere to certain mineral phases. In addition, I used Raman and FTIR spectroscopy to query whether biologically derived signals increase in intensity as bacteria grow in culture.
