Methane metabolism and energetics could have important implications in the search for life on Mars.

This video captures the research priorities of our recent expedition to newly discovered methane seeps off the coast of New England.

 

National Geographic // Explorers Week Symposium

As a part of National Geographic's 2016 Explorers Week, held at the organization's Washington, D.C. headquarters, I shared some highlights from the field and explained the importance of studying extreme microbes and their mysterious metabolisms.

 
 

Dive Deeper // Alvin Video Series

To commemorate the Deep Submergence Vehicle Alvin's contribution to scientific research, Woods Hole Oceanographic Institution and UnderCurrent Productions developed a series of videos highlighting the sub's capabilities.

Telepresence technology developed at the University of Rhode Island's Inner Space Center is extending Alvin's reach from the seafloor to land by giving scientists and students on shore a virtual portal onto the sub's support ship, the research vessel Atlantis.
National Geographic Explorer Jeff Marlow from Harvard University uses Alvin to explore the deep ocean in his search for understanding of how methane vents influence highly specialized, methane-eating microbes on the seafloor as well as the planet as a whole.
For anyone who has explored the ocean in Alvin, the first dive is a special time that surpasses almost all others. It is the moment when the vastness of the deep ocean comes into sharp focus and Alvin's special role as one of the world's premiere scientific instruments becomes clear.

lego education // google science Fair

LEGO Education recently launched [WeDo 2.0], which incorporates aspects of computer programming, experimentation, and active inquiry into elementary school curricula. As a scientific consultant on the project, I sought to ensure that skills taught through the modules were consistent with those required by active research scientists. [Press Release]

Through LEGO Education's involvement in the Google Science Fair, I also participated in the "Ask A Scientist" interview series, speaking briefly with 2013 Science Fair finalist Elif Bilgin about the limits of microbial life.

 
 

TED x Beacon Street: What is life?

Even as we send robotic explorers into space to look for signs of life and answer eternal questions of life beyond Earth, scientists lack a coherent definition of the phenomenon. A theoretical underpinning of life is needed, and expeditions to the planet's most extreme environments are helping to broaden our understanding of biological possibilities.

 
 

The front lines of exploration

Technological advancements over the last few decades have dramatically changed the nature of exploration, opening up vast new worlds while minimizing our physical involvement in their investigation. In this contribution to the Caltech Humanities and Social Sciences' "Exploration: The Globe and Beyond" lecture series, I lead a journey from the deep sea to the volcanoes of Vanuatu and the dusty plains of Mars to show how modern exploration happens.

 
 

Our Curiosity

The Curiosity Mars Rover is one of the most complex machines ever built, a fully equipped analytical laboratory rolling around on the surface of another planet. In order to share the beauty of the mission's exploratory spirit and scientific prowess, I co-executive produced and wrote the short film, "Our Curiosity". Narration was provided by Neil DeGrasse Tyson and Felicia Day, and the original score was composed by co-EP and Grammy-nominated composer Austin Wintory.

TED x Caltech: the forces of Exploration

In this brief presentation at the inaugural TEDx Caltech, I offer an impassioned endorsement of the uniting power of exploration, and show how astrobiology is pushing boundaries in exciting ways.
