Dr. Sossina Haile

Professor of Materials Science and of Chemical Engineering,
California Institute of Technology

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. SossinaHaile's research centers on ionic conduction in solids, with the twin objectives of understanding the mechanisms that govern ion transport, and applying such an understanding to the development of advanced solid electrolytes and novel solid-state electrochemical devices. Materials under investigation in Dr. Haile's group include proton-conducting solid acid compounds, proton-conducting perovskites, mixed oxygen- and electron-conducting perovskites, oxygen-conducting oxides, and alkali-conducting silicates. Micropower generators, based on solid oxide fuel cells are particularly attractive for portable power and are the subject of a recently concluded DARPA project in her group.
