Dr Hyoju Park is a Post Doctoral Researcher in the Texas Materials Institute working on advanced aberration corrected transmission electron microscopy. This includes annular dark field scanning transmission electron microscopy, 4D STEM, in-situ TEM, and atomic resolution EEL and EDX spectroscopies. Her research involves developing new methods for preparation and imaging of energy materials, such as batteries, low-dose imaging of beam sensitive materials, and atomic resolution studies of 2D materials. Prior to UT Austin, she completed her PhD in the Department of Materials Science at Ulsan National Institute of Science and Technology (UNIST) in Korea, working with Prof. Zonghoon Lee on aberration-corrected atomic resolution TEM studies of 2D materials and single atom dopants and defects.

I completed my PhD in Physics at the University of Queensland in 2004, and then spent 18 months as a post-doc in New Zealand and Australia, before moving to the Department of Materials at Oxford in November 2006. In October 2008, I was awarded the University of Oxford’s Glasstone Fellowship in Science to start my own research group. At this same time I began a Junior Research Fellowship at Brasenose College. In October 2010, I was awarded a Royal Society University Research Fellowship in the topic of nanomaterials and electron microscopy. From October 2011-2014, I was at Balliol College, as a Junior Research Fellow and member of Governing Body. In September 2012, I moved from Senior Research Fellow to Academic Staff, a ‘Research Lecturer’ in the Department of Materials. In May 2014 I became Associate Professor in the Department of Materials at Oxford University. In July 2014 I became Full Professor in the Department of Materials at Oxford University. In January 2020 I moved to the Cockrell School of Engineering at the University of Texas at Austin to take up a senior hire to lead the new electron microscopy facility in the Texas Materials Institute. In July 2022, I was appointed as the Director of the Texas Materials Institute.

During 2016 I spent a term as Visiting Professor at MIT in the Department of Materials Sciences and Engineering, teaching a special options postgradaute course on 2D Materials and undertaking extensive research collaborations with faculty. I was Visiting Professor in the Department of Energy at Sungkyunkwan University between 2014-2018. In 2017, I was awarded an ERC Consolidator Grant for 5 years on Large Area Transparent Opto-Electronics using 2D materials. I was recognized as a ‘Highly Prolific Author’ for ACS Nano in 2017. In 2019 I became a Fellow of the Royal Society of Chemistry. In 2019 I was the ACS Nano Lectureship winner. 

I collaborate extensively across the world, co-publishing numerous papers together with leading academics from institutions including: MIT, Harvard, Stanford, Berkeley, Tsinghua, Seoul National University, Cambridge, UCL, and Imperial College.

I have a total of >325 publications in peer-reviewed journals and a h-index of 69, with more than 18500 citations since 2004.  I have first/corresponding author publications in Science, Nature Materials, Nature Nanotechnology, Nature Communications (x2), Nano Letters (x16), Physical Review Letters, Advanced Materials (x2), Angewandte Chemie, ACS Nano (x51), primarily on the topic of nanomaterials including nanoscale characterization by aberration corrected transmission electron microscopy, bottom up synthesis by CVD and solution methods, nanoelectronic devices, sensors, and opto-electronics. Recent work has explored single atom dopant catalysts and hybrid nanoparticle:2D material co-catalysts for hydrogen production and fuel cells.
