Sossina Haile
is the Walter P. Murphy Professor of Materials Sceince and Engineering and the co-director of the . Haile's research broadly encompasses solid state ionic materials and devices, with a particular focus on energy technologies. She has established a new class of fuel cells based on solid acid electrolytes and demonstrated record power densities for solid oxide fuel cells. Her more recent work on water and carbon dioxide dissociation for solar-fuel generation by thermochemical processes has created new avenues for harnessing sunlight to meet energy demands. As an ISEN co-director, Haile plays a key role in advancing the work of the Institute by providing direction and insight into sustainability and energy research and education.
