Dr. Peter Ercius completed a Ph.D. in applied and engineering physics at Cornell University in 2009 with a focus on three-dimensional (3D) electron tomography of semiconductor devices. He then joined the NCEM facility as a collaborative postdoctoral researcher for 2 years before being hired as a permanent Staff Scientist of the Molecular Foundry. Peter is currently in charge of the electron tomography program at NCEM and the dual aberration-corrected TEAM 0.5. Dr. Ercius is a leading expert in electron tomography and collaborates with users of the Molecular Foundry on a wide range of projects including S/TEM atomic resolution imaging, electron tomography, 4D-STEM scanning diffraction, in situ liquid TEM, and electron energy loss spectroscopy (EELS).
