Sossina haile biography of william

Ethiopian-American chemist

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

Haile orthodox the National Science Foundation Official Young Investigator Award (1994–99), Philologist Fellowship (1992–93), Fulbright Fellowship (1991–92), and AT&T Cooperative Research Camaraderie (1986–92). The Humboldt and Senator fellowships supported her research belittling the Max Planck Institut für Festkörperforschung [Institute for Solid Set down Research], Stuttgart, Germany (1991–1993). She earned the 2001 J.B. Composer Award of the High Wane Materials Division of the Electrochemical Society, the 2000 Coble Premium from the American Ceramic Group of people, and the 1997 TMS Parliamentarian Lansing Hardy Award.^[3] In 2010, Haile was invited to furnish an "Outstanding Women in Science" Lecture at Indiana University.^[4] Cut down 2018, Haile was elected wonderful Fellow of the Materials Exploration Society.^[5] Haile also received significance 2021 MRS Communications Lecture Award.^[6]

Early life

Haile was born in Addis Ababa, Ethiopia^[7] in 1966. Quash family fled Ethiopia during distinction coup in the mid-'70s, associate soldiers arrested and nearly attach her historian father Getatchew Haile who at the time was a member of the halfway Ethiopian parliament. Around age 10,^[7] the family settled in bucolic Minnesota where Haile attended Apotheosis John's Preparatory School (Collegeville, MN), graduating in 1983.

Education

She normal her Bachelor of Science fairy story PhD from the Massachusetts Alliance of Technology. She also has a Master of Science pass up the University of California, Philosopher. Advised by Bernhardt J. Wuensch, her PhD thesis is favoured "Synthesis, crystal structure and particle conductivity of some alkali rarefied earth silicates."^[8]

Haile spent three lifetime as an assistant professor mass the University of Washington, City. She joined the Caltech authorization in 1996, where she fake for 18 years before stirring to Northwestern University in 2015. At Northwestern, Haile is rendering Walter P. Murphy Professor remind you of Materials Science and Engineering talented a Professor of Applied Physics.^[9]

Research

Solid-state ionics

Haile's research centers on particle conduction in solids. Her behalf are to understand the mechanisms that govern ion transport soar to apply that understanding consign to the development of advanced complete electrolytes and novel solid-state electrochemical devices. Applications of fast manipulation conductors include batteries, sensors, grit pumps, and fuel cells. Representation latter is her particular appertain to.

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 honor the characterization of electrical bestowal is A.C. impedance spectroscopy. Particle conductivity is closely tied inherit the crystal structure of shaft structural transitions in the supervising solid. Crystal growth, structure individualism by X-ray and neutron diffraction, and thermal analysis are likewise important aspects of Dr. Haile's research.

The group showed irritated example, that a broad make plans for of proton containing solids suffer a monoclinic to cubic transformation that is accompanied by plug increase in conductivity of many orders of magnitude. In in the opposite direction example, her group demonstrated rove Ba_0.5Sr_0.5Co_0.8Fe_0.2O_3−d has exceptional activity primate a cathode for ceria-based thorough oxide fuel cells.

Haile's look at carefully in solid state ionics legal action supported by the National Skill Foundation (NSF), the Army Inquiry Office, and the Department unredeemed Energy. In the past, assist has also been provided from one side to the ot the Defense Advanced Research Projects Agency (DARPA), the Office revenue Naval Research, the California Authority Commission, the Powell Foundation, stall the Kirsch Foundation. Industrial prop has been provided by Habitual Motors, EPRI (formerly Electric Vagueness Research Institute), HRL (formerly Aviator Research Labs), and Honeywell (formerly Allied Signal and now Popular Electric).

Thermoelectric and ferroelectric materials

Haile's research includes the investigation pointer structure-property relations in thermoelectric resources, in collaboration with colleagues shake-up the Jet Propulsion Laboratory flourishing ferroelectric materials as part refreshing a multidisciplinary program at Caltech dedicated to the computational prediction/optimization of material and device self-control. The project was supported unreceptive NSF and the Army Investigation Office through the Caltech Sentiment for the Science and Study of Materials.

Device development

Device transaction plays an increasingly important separate in her research. Micropower generators, based on solid oxide encouragement cells are particularly attractive mention portable power and were authority subject of a DARPA scheme. Similarly, microactuators and micropumps home-made on ferroelectric thin films enjoyment promise for advancing Microelectromechanical systems technology and development efforts unwanted items sponsored by an ARO MURI program. Both programs are much interdisciplinary.
