Sossina M. Haile is the Walter P. Murphy Professor of Materials Science and Engineering at Northwestern University, a position she assumed in 2015 after serving 18 years on the faculty at the California Institute of Technology. She earned her Ph.D. in Materials Science and Engineering from the Massachusetts Institute of Technology and as part of her training spent two years at the Max Planck Institute for Solid State Research in Stuttgart, Germany. Haile’s research broadly encompasses materials, especially oxides, for sustainable electrochemical energy technologies. Amongst her many awards, in 2008 Haile received an American Competitiveness and Innovation Fellowship from the U.S. National Science Foundation in recognition of “her timely and transformative research in the energy field and her dedication to inclusive mentoring, education and outreach across many levels.” In 2010 she was the recipient of the Chemical Pioneer Award (American Institute of Chemists), in 2012 the International Ceramics Prize (World Academy of Ceramics), and in 2020 the Turnbull Lectureship (Materials Research Society). She is a fellow of the Royal Society of Chemistry, the Materials Research Society, the American Ceramics Society, the Electrochemical Society, the African Academy of Sciences, and the Ethiopian Academy of Sciences, and serves on the editorial boards of MRS Energy and Sustainability and Joule.
