Lau has over 20 years of experience in microscopy, material characterization, and instru- mentation in diverse applications from semiconductor failure analysis, material science, geosci- ence, and tissue engineering. A regular presenter at many international conferences, he has also published several papers in failure analysis, material characterization, and imaging in the field of x-ray microscopy. He exited from Xradia Inc. (Calif.) after the company was acquired by Carl Zeiss in 2013. He is now the vice president of business development of Sigray Inc., which is pioneering the development of ultra-bright, tunable x-ray sources and advanced x-ray optics for lab instrumentation and synchrotron applications. Sheraz Gul is a systems engineer at Sigray working on the development of micro and phase contrast XRM systems. He received his Ph.D. in physical chemistry from the University of California Santa Cruz where he worked on the synthesis and x-ray spectroscopic studies of doped semicon- ductor quantum dots. During his postdoc at Lawrence Berkeley National Laboratory, his interests included x-ray spectroscopic studies of materials relevant to natural and artificial photosynthesis using synchrotrons and x-ray free electron lasers (XFELs). Guibin Zan received a Ph.D. degree at National Synchrotron Radiation Laboratory, University of Science and Technology of China, Hefei, in 2019. From 2018 to 2019, he worked as a research scholar at the Department of Biomedical Engineering, Rensselaer Polytechnic Institute, Troy, N.Y. Now he is a postdoc at Stanford Synchrotron Radiation Lightsource of the SLAC National Accelerator Laboratory, Stanford University, Calif. His research interests include all aspects of image processing and imaging, particularly with applications in micro array anode structured target source, Monte Carlo simulation, x-ray source, and x-ray grating interferometry for imaging and metrology. David Vine graduated with a Ph.D. from Monash University in 2008. He worked at the Argonne National Lab’s Advanced Photon Source from 2010 to 2016. Next, he worked at Berkeley National Lab’s Advanced Light Source for two years before joining Sigray in 2017. He currently works as the product manager for x-ray microscopy overseeing the development of the TriLambda nanoscale CT and Prisma sub-micron absorption and TriContrast CT systems. Sylvia Lewis co-foundedSigray Inc. andhas spent over a decade in advanced x-ray instrumentation, formerly at the x-ray microscope company Xradia and now at Sigray. She has led the company’s development of applications for its suite of x-ray tools and the company’s patent strategy. She completed her undergraduate degree at Stanford University in electrical engineering. Wenbing Yun is a leading researcher in x-ray imaging, an innovator, a serial entrepreneur, andOSA fellow. He has over sixty issued patents on x-ray technol- ogy. Formerly a beamline scientist, he founded Xradia Inc. Under his leadership, the company became a worldwide leader in high performance x-ray microscopes, and was success- fully acquired by Carl Zeiss, becoming its x-ray microscope division. After the Zeiss acquisition of Xradia, Yun started Sigray Inc. with a mission to make the entire portfolio of synchrotron analytical techniques accessible to laboratories worldwide. Sigray’s products includemicroXRF, XAS, and nano x-ray microscope systems and x-ray source and optics components.
