Sadegh Yazdi, Ph.D., is a Research Associate Professor at the Renewable and Sustainable Energy Institute (RASEI), and the Director of the Facility for Electron Microscopy of Materials (CU FEMM) at the ÀÖ²¥´«Ã½. His research interests include developing novel electron microscopy techniques for exploring the links between the underlying atomic arrangements of energy-related materials and their performance, properties, and synthesis. To characterize nanostructures at atomic levels, Sadegh uses advanced electron microscopy techniques such as aberration-corrected scanning transmission electron microscopy (AC-STEM), low-voltage and monochromated high-resolution transmission electron microscopy (HRTEM), off-axis electron holography (OAEH), monochromated electron energy loss spectroscopy (EELS), electron tomography (ET), and a wide range of in-situ electron microscopy techniques.
