Staff Scientist, NCEM
Colin Ophus received his PhD in Materials Engineering from the University of Alberta in Canada. He was then awarded a full Postdoctural Research Fellowship from the National Sciences and Engineering Research Council of Canada. This postdoctoral research was performed jointly between the National Center for Electron Microscopy and the MSE Department at the University of California Berkeley. He then became a project staff scientist at NCEM, and is currently a Molecular Foundry research scientist in NCEM.
Dr. Ophus works primarily on developing methods, algorithms and codes for simulation, analysis and instrument design for high resolution and scanning transmission electron microscopy (HRTEM and STEM). He provides computational support to facility users for quantitative analysis of electron micrographs, and aims to close the gap between experimentally available data and theoretically accessible systems. He has written several software packages to perform image simulation, drift correction and large dataset visualizations, as well as thousands of data analysis codes. His current research topics include:
- HRTEM and STEM Simulation algorithms.
- Quantum measurement protocols for electron microscopy.
- Atomic electron tomography.
- Phase contrast imaging methods such as MIDI-STEM and ptychography.
- Nanobeam electron diffraction.
- Density Functional Theory (DFT).
- Molecular Dynamics (MD).
- Inline and off-axis electron holography.
- Electronic structure inversion algorithms in 2 and 3 dimensions.
