Biography
Colin Ophus is a staff scientist at NCEM, part of the Molecular Foundry, at Lawrence Berkeley Lab. His research and user program focus on transmission electron microscopy (TEM) and scanning TEM (STEM), as well as computational microscopy and materials science. He has published over 190 peer reviewed articles, given over 80 invited talks, and taught dozens of workshops around the world. In 2018 he received a DOE Early Career award, and in 2022 he was awarded the Burton medal from the Microscopy Society of America (MSA). He has also received awards for top papers in the field of microscopy from the MSA in 2019 and 2021, and the Molecular Foundry Outstanding Staff Service Award in 2020.
Research Interests
Colin’s research focuses on experimental methods, reconstruction algorithms, and codes for simulation, analysis and instrument design of TEM, STEM and a 4D-STEM. He provides data analysis and 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:
- 4D-STEM Experimental Design
- Phase contrast STEM methods including DPC, MIDI-STEM, parallax and ptychography.Nanobeam electron diffraction.
- Atomic electron tomography.
- Quantitative simulation of TEM and STEM experiments.
- in situ TEM data analysis methods.
- Density functional theory (DFT).Molecular dynamics (MD).
- Inline and off-axis electron holography.
- Electronic structure inversion algorithms in 2 and 3 dimensions.
