Ping-Luen (Baron) Ho's research focuses on developing advanced aberration-corrected transmission electron microscopy (AC-TEM) techniques, including 4D-STEM ptychography, electron energy-loss spectroscopy (EELS), and electron energy-loss magnetic chiral dichroism (EMCD).
In Oxford, Baron's DPhil project makes use of low-dose electron ptychography to verify the complex structure of beam-sensitive zeolites. The detailed structure characterisation by complementarity between synchrotron radiation technique, and STEM quantification, combining imaging simulation and DFT provides a comprehensive understanding of the potential correlation of atomic structures with catalytic activity.
Ping-Luen (Baron) Ho completed his DPhil at University of Oxford in 2024, where he was a Swire Scholar co-supervised by Prof Peter D Nellist FRS and Prof S C Edman Tsang. Before he moved to Oxford, from 2015 and 2018, he was awarded the Aachen-Tsinghua Junior Fellowship under the supervision of Prof Xiaoyan Zhong, with mentorship from Prof Jing Zhu, Prof Joachim Mayer and Prof Rafal Dunin-Borkowski. His research during this period focused on the magnetic ordering of perovskite-based materials using electron energy-loss magnetic chiral dichroism (EMCD) and spherical aberration-corrected transmission electron microscopy (AC-TEM). Ping-Luen holds a double-majored with BSc in Materials Science and Physics at National Tsing Hua University, MEng in Materials Science and Engineering at Beijing's Tsinghua University, in collaboration with Ernst Ruska-Centre (ER-C) at Forschungszentrum Jülich.
