Sujoy Roy and Cheng Wang, scientists at Berkeley Lab’s Advanced Light Source (ALS), have been elected 2026 Fellows of the American Physical Society (APS).
Roy was elected through the APS Topical Group on Magnetism and Its Applications for leadership in developing coherent soft X-ray scattering tools and fast detectors to probe the structure, motion, and orbital angular momentum of quantum materials, and for his efforts to expand community access to these capabilities and mentor future scientists.
Roy is a senior scientist and program lead for Coherence and Magnetism at the ALS, where he leads the coherent X-ray scattering program. His research uses resonant coherent X-ray scattering to study magnetic and quantum materials, including the non-equilibrium behavior of magnetic phase transitions. Roy is also an investigator in Berkeley Lab’s Materials Sciences Division.
Wang was elected through the APS Forum on Industrial & Applied Physics for pioneering resonant soft X-ray scattering instrumentation and methodology, which are enabling physics-based metrology for organic electronics, energy materials, and EUV lithography, critical to energy applications and semiconductor manufacturing.
A staff scientist in the ALS Resonant Elastic & Inelastic X-Ray Scattering program, Wang develops and applies resonant soft X-ray scattering methods to characterize the nanoscale structure and chemistry of complex materials. He is the primary contact for the ALS resonant soft X-ray scattering beamline and has also led development of capabilities for applying the technique to microelectronics metrology.
APS Fellowship recognizes members who have made significant contributions to physics through research, applications, leadership, or service.
