Xiaohao Yang earned his undergraduate degree from Tsinghua University in Material Science (Beijing, China), and now enrolled in Ph.D. program in Dept. of Applied Physics and Applied Mathematics, Columbia University. He has a board range of interests, including studying the atomic structure of semiconductor quantum dots using Pair Distribution Functions; statistic uncertainties analysis and reliability study in data reduction; studying the heterogeneous structure of nano-scale structure in meso-scale using computed tomography PDF(ctPDF). He also works on developing software, including 2D powder diffraction image processing Python package diffpy.srxplanar and commercial end-to-end PDF analysis software solution xPDFsuite and ePDFsuite.
