Research

Professor Bilge Yildiz’s research aims to gain a predictive understanding of the relation between the structure and physical chemistry of material surfaces in increasingly harsh and coupled environments of chemical reactivity and applied stress. Ideal applications of this coupling in her research program are: 1) electrocatalytic activity on high temperature oxides for fuels and electricity production (fuel cells and electrolysis), and 2) metal corrosion. These research sub-areas are connected through a fundamental science problem: transport and reactivity of charged defects on solid state ionic nanoscale thin films. In particular, she focuses on understanding and driving the kinetics of surface activity and charge transport via the mechanical state of the thin films. The scientific insights gained from her research can provide a rational basis to design desired material interfaces from an atomic scale, and contribute to the longevity of nuclear reactors and to the development of efficient energy conversion systems coupled to nuclear reactors as well as other high temperature heat sources as concentrated solar power.

Yildiz's research approach tightly integrates experimental and computational techniques at comparable scales. Her group’s experimental specialization is the probing of surface atomic and electronic structure using scanning tunneling microscopy in harsh operando conditions. On the computational front, her group is advancing multiscale methods to overcome the timescale limitation of traditional atomistic methods.
