Hiroshi Imanaka
Senior Scientist
Curriculum Vitae: 

Dr. Imanaka's major research interest is the inventory and evolution of the volatile CHNOS elements in planetary atmospheres, planetary surfaces, and, the early solar system towards the understanding of the origin and evolution of life and habitable environments. 
He is working on comprehensive laboratory studies of complex organic chemistry related to the atmospheres of Titan and the early Earth. He studies characteristic fingerprints (elemental/isotopic composition, structure, and spectroscopic characteristics) in plausible organic macromolecules in planetary environments.
A comprehensive understanding of such fingerprints is a key for constraining the physical-chemical environments, elemental cycles, and energy balance from available, or potentially available, sets of astronomical/planetary/geological observations.

Organic Aerosols in the Early Earth Atmosphere: Reaction Network an Its Isotope Signature

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.
