Tomas Aidukas

Tomas Aidukas is a postdoctoral researcher at the Paul Scherrer Institute (PSI) in Switzerland, working in the Laboratory for Macromolecules and Bioimaging within the Center for Photon Science. He is a member of the cSAXS group at the Swiss Light Source, where he conducts research in computational imaging and ptychography.

Education:

• B.Sc. in Theoretical Physics, University of Glasgow (2016)
• Ph.D. in Intelligent Sensing and Measurement, University of Edinburgh/Glasgow (2021)

His research focuses on developing novel computational imaging techniques, particularly ptychography and Fourier ptychography, to overcome limitations in imaging systems. He specializes in algorithm development for image reconstruction and calibration, with current goals of pushing the resolution limits of 3D ptychographic tomography using X-rays and applying data-driven methods for integrated circuit inspection. His work bridges theoretical optics with practical applications in microscopy and tomography.

His recent publications (2019-2022) demonstrate a strong focus on Fourier ptychographic microscopy, including high-speed multi-camera systems, low-cost open-source hardware solutions, and quantum correlation techniques. The work consistently addresses phase retrieval challenges while advancing sub-micron resolution capabilities across optical and X-ray domains.

Scientific Awards: None mentioned.

Dr. Aidukas leads multiple research initiatives including bridging the resolution gap between X-ray nano-tomography and electron microscopy, high-throughput integrated circuit inspection, and data-driven X-ray tomography methods. His industrial collaboration with ZEISS produced a patented depth metrology algorithm, and he provides operational support at the cSAXS beamline.

He operates within the cSAXS group at PSI's Swiss Light Source, maintaining academic ties with the University of Glasgow's Imaging Concepts Group and industrial partnerships with companies like ZEISS for algorithm development and hardware implementation.
