CURRICULUM VITAE-SHARON SHWARTZ  *Sharon Schwartz Bio

Sharon Shwartz received his B.A. in Physics from the Technion–Israel Institute of Technology in 2001 and completed his Ph.D. in 2008 under the supervision of Professor Moti Segev. His doctoral research focused on light-induced changes in the optical, mechanical, and electrical properties of the semiconductor CdZnTe. During his doctoral studies he was among the first recipients of the prestigious Adams Fellowship of the Israel Academy of Sciences and Humanities.

After completing his Ph.D., he joined the group of Professor Stephen Harris at Stanford University as a postdoctoral researcher. During this period he began exploring how concepts from nonlinear and quantum optics, traditionally studied at visible wavelengths, could be extended to the x-ray regime, motivated in part by the emergence of x-ray free-electron laser facilities.

In 2012 he joined the Department of Physics at Bar-Ilan University, where he is currently a Professor. His research focuses on nonlinear and quantum phenomena in the x-ray region of the electromagnetic spectrum and on developing new measurement techniques inspired by concepts from quantum and statistical physics. His group investigates the interaction of intense x-ray fields with matter and develops innovative approaches for probing materials with atomic spatial resolution and ultrafast temporal sensitivity.

Over the past decade, Professor Shwartz and his collaborators have made several pioneering contributions to the emerging field of x-ray quantum and nonlinear optics. These include advances in x-ray parametric down-conversion and entangled x-ray photon generation, the demonstration of nonlinear optical processes at x-ray energies, and the development of quantum-inspired imaging methods such as x-ray ghost imaging for applications ranging from elemental mapping to computed tomography using scattered radiation.
