Ethiopian Role Model: Professor Sossina M. Haile

Ethiopia has many scholars in North America and Europe. One of my favoured Ethiopian professors is Sossina M. Haile.

Sossina Haile, Associate Professor of Materials Science.

This ever young looking professor is a real scientist and award winning scholar. Below is Prof Haile’s profile, taken from her website:

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 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. Technological applications of fast ion conductors include batteries, sensors, ion pumps and fuel cells. It is to this last area that Dr. Haile’s work is most closely tied.

Materials under investigation in Dr. Haile’s group include proton-conducting solid acid compounds, proton-conducting perovskites, mixed oxygen- and electron-conducting perovskites, and oxygen-conducting oxides. The standard technique used in her group for the characterization of electrical properties is A.C. impedance spectroscopy. Because ionic conductivity is closely tied to the crystal structure of and structural transitions in the conducting solid, crystal growth, structure determination by X-ray and neutron diffraction, and thermal analysis are also important aspects of Dr. Haile’s research. Using these methods, her group has shown, for example, that a broad range of proton containing solids undergo a monoclinic to cubic transition that is accompanied by an increase in conductivity of several orders of magnitude.

In another example, her group has demonstrated that Ba0.5Sr0.5Co0.8Fe0.2O3-d has exceptional activity as a cathode for ceria based solid oxide fuel cells. Dr. Haile’s work in solid state ionics and electrochemistry is supported by the National Science Foundation, the Army Research Office, the Stanford Global Climate and Energy Program (GCEP) and the Moore Foundation, through its support of the Caltech Center for Sustainable Energy Research (CCSER). In the past, support has also been provided by the Defense Advanced Research Projects Agency (DARPA), the Office of Naval Research, the California Energy Commission, the Department of Energy (DOE), the Powell Foundation and the Kirsch Foundation. Industrial support has been provided by General Motors, EPRI (formerly Electric Power Research Institute), HRL (formerly Hughes Research Labs) and Honeywell (formerly Allied Signal and now General Electric).

While new materials discovery and understanding are central themes in many of Haile’s programs, device development plays an increasingly important role in her research. For example, under GCEP support, her group aims, in collaboration with D. Goodwin in Mechanical Engineering, to demonstrate hierarchically structured solid oxide fuel cells with record-breaking power density at intermediate temperatures. The transition from novel materials to useful devices requires the collective efforts of researchers from a broad range of fields, and both programs are highly interdisciplinary in nature.

  4. Thanks for the info.But could you tell us more about her? Where was her early schooling? Did she do her elementaries and secondaries in Ethiopia or in the U.S? How did she come to to science instead of,say,history or other humanties studies? Who is her historian father?
    She is sooo cooool!

  5. I really appreciate her on the topic she is handling…using solar cells for the limited fuel sources…what a bright future we have!
    Go ahead gil.

  6. I’d like to say Ethiopian hero. thanks to introduce the meaning of Ethiopia.i haven’t word to introduce you thanks for all things.
    FOR Ethiopian hero

  7. oh!!! i have no words to expression about u
    any how i say u re intelligent and clever the first woman in Ethiopia
    how can u succeed Ur professor?
    how was Ur life now ?
