A huge congratulations to Xiaohao for successfully defending his thesis! He has been an integral member of our group for the past four years and has carried out an exceptional graduate career pushing the boundaries in advanced algorithm development, complex modeling, and use of the pair distribution function technique for characterization of a wide range of technologically important and structurally complicated materials. We are happy for his success, sad to see him go, and excited for the great work he will continue to do at his new job! Thank you so much for everything Xiaohao. We truly wish you all the best as your career continues to develop.
