Sossina Haile received her B.S and Ph.D (1992) from the Massachusetts Institute of Technology, and M.S. from the University of California, Berkeley. Before joining the Caltech faculty in 1996, Haile spent three years as an assistant professor at the University of Washington, Seattle. Haile has received the NSF National Young Investigator Award (1994-99), Humboldt Fellowship (1992-93), Fulbright Fellowship (1991-92), and AT&T Cooperative Research Fellowship (1986-92). The Humboldt and Fulbright fellowships supported her research at the Max Planck Institut für Festkörperforschung [Institute for Solid State Research], Stuttgart, Germany (1991-1993). She is the recipient of the 2001 J.B. Wagner Award of the High Temperature Materials Division of the Electrochemical Society, the 2000 Coble Award from the American Ceramics Society and the 1997 TMS Robert Lansing Hardy Award.
Sossina Haile's research broadly encompasses solid state ionic materials and devices, with particular focus on energy technologies. She has established a new class of fuel cells based on solid acid electrolytes and demonstrated record power densities for solid oxide fuel cells. Her more recent work on water and carbon dioxide dissociation for solar-fuel generation by thermochemical processes has created new avenues for harnessing sunlight to meet energy demands.
