Antoine Wojdyla, Ph.D.

Antoine Wojdyla is a staff scientist at the Advanced Light Source, a synchrotron radiation facility located at Lawrence Berkeley National Laboratory. His works focuses on x-ray optical design and the development of new technologies for synchrotron optics.  He led the optical design of the feature beamlines for the upgrade of the Advanced Light Source. He also has interest in coherent imaging optics and computational imaging techniques such as Fourier ptychography.

He holds a PhD from Ecole Polytechnique, a school near Paris (France) where he conducted research of terahertz radiation for biological imaging, using ultrafast techniques and polarization.

Xiaya Chong, Ph.D.

Xiaoya Chong received her Ph.D. degree in the Department of Computer Science, City University of Hong Kong and her B.Eng. degree from Zhejiang University and the M.Sc. degree from the Hong Kong University of Science and Technology.. Her research interests include Machine Learning, Deep Learning, Computer Vision and Computational Biology. During her Ph.D. study, she also undertook research internships at Tencent AI Lab and Noah's Ark Lab-Hong Kong, where she focused on utilizing convolutional neural networks, transformers and MLPs for low-SNR data analysis.

Ken Goldberg, Ph.D.

Ken Goldberg is the lead of the Photon Science Development group at the Advanced Light Source (Lawrence Berkeley National Laboratory), where he oversees the development of a suite of about 40 beamlines, serving over a thousand of users each year.  He worked for many years on the development of Extreme Ultraviolet microscopy, in close collaboration with industry leaders such as Intel and IDM, and on the metrology of soft x-ray optics. He holds a PhD from UC Berkeley

Past members

Gautam Gunjala, PhD

Dr. Gautam Gunjala earned a doctorate from UC Berkeley in 2022, which was focused on x-ray wavefront measurements and adaptive optics. He applied machine learning techniques to push the the performance of x-ray bimorph mirrors to their limits and achieve diffraction-limited quality in open-loop operation. He also worked on the use of the speckle caused by intrinsic sample roughness to characterize the aberrations of state-of-the-art Extreme Ultraviolet microscopes. He was the recipient of a DOE SCGSR grant.

He currently works at AMSL, the leading semiconductor manufacturing company, in San Jose, CA.

Paola Luna

Paola Luna at the Advanced Light Source
(Lawrence Berkeley National Laboratory, CA, USA)

Paola Luna received a BS in Physics from San Diego State University.  She worked on the use of x-ray adaptive optics in grating monochromator to achieve very high photon energy resolution and engineer the instrument function of the grating monochromator to achieve two-color imaging and other exotic used of these devices. Her simulations based on real data from existing devices showed that the current state of the art meets the specification requirements to achieve these new imaging schemes.

She is currently exploring PhD programs in optics and astrophysics.

Mahmoud Morsy

Mahmoud Morsy holds a MS in Mechanical Engineering from UC Berkeley. He worked on the use of speckle to accurately determine the longitudinal position of an object, without using any reference. His  simulations showed that this technique, named "Supreme" (for Speckle-based Position Monitoring) could determine the absolute position known to ~10nm at a 10 mm distance, and experimentally demonstrated 

He currently works at Astra, a launch vehicle company located in Alameda, CA.
