This project is centered around the hypothesis that exposure to environmental extremes results in intracellular oxidative stress, which is modulated by the elemental content of cells. We are using X-ray fluorescence imaging and X-ray transmission microscopy at SSRL (Stanford Synchrotron Radiation Lightsource) to map the elemental composition of halophilic cyanobacteria from the Atacama desert and of green algae, and determine changes that may represent responses to transient fluctuations in the environment. Linking these with the genomic and molecular changes in cells helps uncover a possible mechanism of adaptation and evolution.

If we are to understand complex microbial communities we need to understand not only the microbes themselves but their community dynamics as well.

Experimental simulations of Titan's atmospheric and surface chemistries in order to understand the formation of complex organic molecules as well as the abiotic formation of prebiotic molecules, providing important clues to the origin of life on the early Earth.

Continued improvements in the Planetary Data System, specifically the Rings Node, including development of an interactive website to engage the public about the diversity and significance of planetary ring systems.

The goal of this projects is to develop a new and more sensitive method for the determination of bioburdens for planetary protection purposes.

Planetary habitability is the measure of a planet's (or a satellite’s) potential to develop and sustain life. While life beyond the Earth is still uncertain, planetary missions show that conditions for habitability (i.e. water, energy, nutrients) were met in the past, and still possibly today in specific environments on Mars and on several moons of the outer solar system. Central to our investigation is the notion that habitability evolves with time. For instance, some planets could have been habitable in the past and may not be anymore; the Earth, that is not only habitable but has developed life, has seen its broad range of habitats change over geological times through climate cycles and planetary-scale catastrophes (e.g., asteroid and comet impacts) that were followed sometimes by near complete extinctions and the redistribution of habitats and dominant species. Currently, Global Warming is showing how rapidly habitats and species can disappear following climate change. Yet, humanity’s ability to explore and understand its environment can have positive consequences, which is in the case of our planet, to reduce human-induced biodiversity loss, and for other planets, to explore and engineer apparently sterile worlds (e.g., the Moon and Mars) to make them habitable and productive for future generations.

A comprehensive study of the spectral characteristics of carbonaceous species with the goal of understanding the effects of size, molecular structure, clustering, and charge on the spectra, and allowing us to more accurately interpret the emission characteristics of the interstellar medium.
