Henderson James (Jim) Cleaves

Henderson (Jim) Cleaves' research in organic geochemistry is concerned principally with abiological organic synthesis, the question of how life arose on Earth, and methods for detecting Life on other planets. Presently he is involved in a project with Robert Hazen regarding the interactions of organic compounds with mineral surfaces.

Jim earned his Ph.D. from the University of California, San Diego, in 2001.
