Expertise
Method development and scientific software development including the following.
- Image processing methods for tomography: distortion correction, phase retrieval, artifact removal, image alignment, image reconstruction, image restoration.
- Python software for data processing & tomography: Discorpy-software for camera calibration and distortion correction; Sarepy-software for removing ring artifacts; Algotom-software for tomographic data processing.
Education
After obtaining a B.Sc and a M.Sc degree in physics from the University of Science, VNUHCM, Vietnam; Nghia pursued a PhD study at Singapore Synchrotron Light Source, National University of Singapore and graduated in 2013.
Professional Appointments
Nghia joined Diamond Light Source as a postdoc at Beamline I12 in 2013, and moved to scientific software group as a data analysist scientist in 2018. In 2022, he joined NSLS-II, Brookhaven National Laboratory, and has been working as a beamline scientist at the HEX beamline.
