About

I am an astrobiologist interested in understanding how the ingredients that make a world habitable are delivered to terrestrial planets in their host star’s habitable zone. In particular, I am interested in understanding the distribution of volatiles in the early solar system, and how water was delivered to Earth.

I’m involved in large international collaborations both for research and graduate and early career field training.

I believe that the key to innovative science involves interdisciplinary research, and I lead the UHNAI Astrobiology research team at UH.

Research

Comets are icy left-overs of the planet formation process that have been preserved cold since the time of formation. Studies of these small objects provide clues about the chemistry and dynamics in our solar system’s protoplanetary disk. I use 8 and 10-m class telescopes on Maunakea and in Chile to study comets as well as a number of smaller telescopes around the world. I have been a Co-Investigator on the Deep Impact, EPOXI and Stardust-NeXT missions.

Understanding the origin of Earth’s water requires an interdisciplinary approach, with insight from the fields of protoplanetary disk chemistry, dynamics, cosmochemistry and geochemistry. With my team we are studying deep mantle rocks to determine the isotopic composition of Earth’s primordial water. I am leading the development of a space mission to explore volatile materials in the asteroid belt to assess whether this region is key to providing Earth’s water.
