ARCHIPELAGO: My colleagues and I are conducting a search for planets around nearby K and M stars (less massive than the Sun) that uses a combination of the Doppler and photometric techniques. Our survey is sensitive to planets as small as 10 Earth masses and is deliberately designed to preferentially find planets that transit their parent star.
Cosmochemical variability and planetary habitability
ISBOX (Icelandic Subglacial BiolOgy eXploration): I am the U.S. PI of an Icelandic-U.S. team that that has investigated three volcanic lakes covered by a 300-m-thick glacier in Iceland. Two of these lakes contain very unusual microbial communities that lack Archaea and where homoacetogenesis replaces methanogenesis
