Eric R. Hoglund

            After graduating with a Bachelors in Material Science from NC State University in 2015 Eric joined the Material Science department at the University of Virginia (UVA) where he earned his Masters and PhD. During his doctoral degree he focused on investigating interfaces and phase transformation using the high-spatial resolution of a transmission electron microscope (TEM). This included a variety of techniques ranging from in-situ­ heating and cryogenics, imaging, diffraction, and electron energy-loss spectroscopy (EELS) in materials ranging from metals to functional semiconductors and ceramics. He then took a postdoctoral appointment working jointly with the Mechanical Engineering and Material science department at UVA where he learned time-domain optical spectroscopies like Brillouin zone scattering and time-domain thermal reflectance, which provide information about phonon propagation in materials. He continued with his material characterization using TEM to understand what was impacting the measured phonon properties, which included trips to ORNL for vibrational EELS measurements. After his two years of post-doctoral research at UVA Eric joined as a post-doctoral researcher at ORNL where he continued with vibrational EELS and advanced 4D-STEM techniques to understand the complex interplay between atomic arrangements, bonding and phonons at heterogeneities in quantum materials.
