Ping-Luen (Baron) Ho's research in the past seven years has been focusing on developing advanced (aberration-corrected) TEM techniques, including 4D-STEM, electron energy-loss spectroscopy (EELS), and electron energy-loss magnetic chiral dichroism (EMCD).

In Oxford, Baron's DPhil project makes use of simultaneous incoherent image and coherent ptychography to characterise the strategic placement of defined metal catalytic active sites quantitatively, and to relate catalytic performance to the size and shape selectivity of zeolite pores, and the synergy between different chemical reactions. His research is involved in application of several material systems: low-dimensional thin film, nitrogen vacancies and the polar surface of metal oxides, atomic interface and magnetic performance of perovskites, dislocations of metals, semiconductors, and quantum materials.

Ping-Luen (Baron) Ho double-majored with BSc in Materials Science and Physics at National Tsing Hua University in 2014. He received MEng in Materials Science and Engineering at National Centre for Electron Microscopy at Beijing's Tsinghua University and Ernst Ruska-Centre (ER-C) in Forschungszentrum Jülich. Between 2015 and 2018, Baron worked under the supervision of Dr Xiaoyan Zhong, Prof Joachim Mayer and Prof Rafal Dunin-Borkowski studying the magnetic ordering of perovskites-based electron energy-loss magnetic chiral dichroism and spherical aberration-corrected electron microscopy. He joined the group in October 2018 as Swire Scholar DPhil Candidate co-supervised by Prof Peter D Nellist FRS and Prof S C Edman Tsang. Baron Ho is currently a Fellow of the Royal Microscopical Society (FRMS) and an Associate Member of the Royal Society of Chemistry (AMRSC).
