 Haile's research includes the investigation of structure-property relations in thermoelectric materials, in collaboration with colleagues at the Jet Propulsion Laboratory and ferroelectric materials as part of a multidisciplinary program at Caltech dedicated to the computational prediction/optimization of material and device behavior.The project was supported by NSF and the Army Research Office through the Caltech Center for the Science and Engineering of Materials.Device development plays an increasingly important role in her research.
