Antoine Islegen-Wojdyla

Antoine Wojdyla is a research scientist at the Advanced Light Source, a national user facility hosted at Lawrence Berkeley National Laboratory. He currently works on the design and simulation of the feature beamlines for ALS-U, the diffraction-limited storage ring upgrade of the light source, in order to leverage the high brightness and coherence for microscopy and spectroscopy in the soft x-ray regime, for application in physics, chemistry and biology.

His work focuses on the use of diffractive optics, wavefront sensors and deformable mirrors to enable and maintain diffraction-limited performances in insertion device beamlines, developing new technologies for synchrotrons and free-electron lasers. He was previously developing novel imaging techniques for EUV lithography based on the SHARP EUV microscope, in collaboration with semiconductor manufacturing companies such as Intel and Samsung.

He earned his PhD from École Polytechnique and his Master’s degree from Ecole Centrale/Aix-Marseille University (France.)
