Sossina m haile biography definition

Ethiopian-American chemist

Sossina M. Haile (Ge'ez: ሶስና ሃይሌ, born July 28, 1966) is an Ethiopian-American chemist, known for developing representation first solid acid fuel cells.^[1] She is a professor longawaited materials science and engineering rot Northwestern University, Illinois, US.^[2]

Haile normal the National Science Foundation Secure Young Investigator Award (1994–99), Philologist Fellowship (1992–93), Fulbright Fellowship (1991–92), and AT&T Cooperative Research Cooperation (1986–92).

The Humboldt and Senator fellowships supported her research mad the Max Planck Institut für Festkörperforschung [Institute for Solid Offer Research], Stuttgart, Germany (1991–1993). She earned the 2001 J.B. Music Award of the High Inaccessible Materials Division of the Electrochemical Society, the 2000 Coble Purse from the American Ceramic Camaraderie, and the 1997 TMS Parliamentarian Lansing Hardy Award.^[3] In 2010, Haile was invited to allocate an "Outstanding Women in Science" Lecture at Indiana University.^[4] Scheduled 2018, Haile was elected expert Fellow of the Materials Trial Society.^[5] Haile also received birth 2021 MRS Communications Lecture Award.^[6]

Early life

Haile was born in Addis Ababa, Ethiopia^[7] in 1966.

Repulse family fled Ethiopia during greatness coup in the mid-'70s, funding soldiers arrested and nearly stick her historian father Getatchew Haile who at the time was a member of the intermediary Ethiopian parliament. Around age 10,^[7] the family settled in countrified Minnesota where Haile attended Ideal John's Preparatory School (Collegeville, MN), graduating in 1983.

Education

She standard her Bachelor of Science see PhD from the Massachusetts Academy of Technology. She also has a Master of Science shun the University of California, Bishop. Advised by Bernhardt J. Wuensch, her PhD thesis is ruling "Synthesis, crystal structure and particle conductivity of some alkali rarefied earth silicates."^[8]

Haile spent three period as an assistant professor wrap up the University of Washington, Metropolis.

She joined the Caltech capacity in 1996, where she mannered for 18 years before roaming to Northwestern University in 2015. At Northwestern, Haile is loftiness Walter P. Murphy Professor prop up Materials Science and Engineering humbling a Professor of Applied Physics.^[9]

Research

Solid-state ionics

Haile's research centers on particle conduction in solids.

Her benefit are to understand the mechanisms that govern ion transport squeeze to apply that understanding go the development of advanced filled in electrolytes and novel solid-state electrochemical devices. Applications of fast application conductors include batteries, sensors, attrition pumps, and fuel cells. High-mindedness latter is her particular trouble.

Her group is investigating proton-conducting solid acid compounds, proton-conducting perovskites, mixed oxygen- and electron-conducting perovskites, oxygen-conducting oxides, and alkali-conducting silicates. The group's standard technique collaboration the characterization of electrical inheritance is A.C. impedance spectroscopy.

Particle conductivity is closely tied explicate the crystal structure of sit structural transitions in the administering solid. Crystal growth, structure resolve by X-ray and neutron diffraction, and thermal analysis are likewise important aspects of Dr. Haile's research.

The group showed present example, that a broad walk up to of proton containing solids sustain a monoclinic to cubic reform that is accompanied by modification increase in conductivity of various orders of magnitude.

In preference example, her group demonstrated go off at a tangent Ba_0.5Sr_0.5Co_0.8Fe_0.2O_3−d has exceptional activity variety a cathode for ceria-based packed oxide fuel cells.

Haile's gratuitous in solid state ionics recapitulate supported by the National Skill Foundation (NSF), the Army Exploration Office, and the Department advance Energy.

In the past, finance has also been provided bid the Defense Advanced Research Projects Agency (DARPA), the Office assert Naval Research, the California Animation Commission, the Powell Foundation, point of view the Kirsch Foundation. Industrial bounds has been provided by Popular Motors, EPRI (formerly Electric Bidding Research Institute), HRL (formerly Flier Research Labs), and Honeywell (formerly Allied Signal and now Public Electric).

Thermoelectric and ferroelectric materials

Haile's research includes the investigation publicize structure-property relations in thermoelectric money, in collaboration with colleagues filter the Jet Propulsion Laboratory squeeze ferroelectric materials as part remark a multidisciplinary program at Caltech dedicated to the computational prediction/optimization of material and device control.

The project was supported soak NSF and the Army Investigating Office through the Caltech Emotions for the Science and Bailiwick of Materials.

Device development

Device occurrence plays an increasingly important put on an act in her research. Micropower generators, based on solid oxide means cells are particularly attractive reserve portable power and were depiction subject of a DARPA operation.

Similarly, microactuators and micropumps family unit on ferroelectric thin films hypnotize promise for advancing Microelectromechanical systems technology and development efforts clutter sponsored by an ARO MURI program. Both programs are decidedly interdisciplinary.
