The scope and topical coverage of Optical Materials Express has broadened since the launch of the Journal and continues to grow. To ensure that the editorial board continues to represent both well-established and emerging research areas, I have added four new members. I am very pleased to introduce Alan Bristow, Joris Lousteau, Jong Hyeok Park and Robert Simpson. The new Associate Editors will cover topics ranging from ultrafast optics and fiber systems to energy conversion, bringing expertise in optical materials including glasses, chalcogenides, ceramics, perovskites and organics. I am happy to have such outstanding representation for these areas of research and look forward to working with these new colleagues.

Alan Bristow

Alan D. Bristow received his PhD in Physics in 2004 from the University of Sheffield, UK. Between 2003 and 2010, he was a Postdoctoral Fellow at the University of Toronto, Canada and then a Research Associate at JILA (a division of the National Institute of Standards and Technology on the campus of the University of Colorado at Boulder, USA). He served as an Adjunct Instructor at Colorado School of Mines, USA in 2009, Assistant Professor at West Virginia University (WVU), USA from 2010 to 2016 and is currently Associate Professor at WVU, leading the Ultrafast Nanophotonics Group. He is a Member of the American Physical Society and a Senior Member of The Optical Society. In 2017, he became an Associate at the National Institute of Standards and Technology, USA and was a guest researcher at the Technische Universität – Dortmund, Germany.

Joris Lousteau

Joris Lousteau received his PhD in 2005 from The University of Nottingham, UK. He then engaged in successive international research projects, as a Research Fellow/Scientist at the University of Kent, UK from 2004 to 2005, at University of Leeds, UK from 2005 to 2008 and at Politecnico di Torino, Italy from 2008 to 2014, and then as a Senior Research Fellow at the University of Southampton, UK from 2014 to 2018. In 2015, he was awarded a Marie Skłodowska Curie Indvidual Fellowship and in 2018, he was appointed Associate Professor at Politecnico di Milano, Italy. His fields of interest concern the engineering of novel glass and glass ceramics and the manufacture of optical waveguides from the latter materials with the aim to develop novel fiber laser, supercontinuum sources, thermal imaging fiber bundles or high energy particles imaging arrays.

Jong Hyeok Park

Jong Hyeok Park received his PhD in Chemical and Biomolecular Engineering in 2004 from KAIST, South Korea and was subsequently a Postdoctoral fellow at the University of Texas at Austin, USA. In 2005 he worked as Senior Researcher at LG Chemistry Research Park, South Korea and then at Electronics and Telecommunications Research Institute, South Korea in 2007. He was appointed to Assistant Professor at Sungkyunkwan University (SKKU), South Korea in 2008 and Associate Professor in 2012. He moved to Yonsei University, South Korea in 2015 as Associate Professor and was later appointed to his current role as Professor. His research interests include organic/perovskite solar cells, solar water splitting for H2 production, energy storage devices, CH4 conversion, and nanomaterials for energy devices. He has received numerous awards and honors including the PBFC award from the Korean Electrochemical Society in 2012, the SKKU Yong Fellowship in 2012 and SKKU Excellent Research Award from 2011 to 2014 from Sungkyunkwan University, and the Best Research Award from Yonsei University in 2017. He has published over 230 papers in scientific journals and patented over 60 inventions.

Robert E. Simpson

Robert E. Simpson received his PhD from the Optoelectronics Research Centre at the University of Southampton, UK in 2008. After his PhD, Robert was awarded the Japanese Society for the Promotion of Science fellowship and spent 3.5 years at the Japanese national institute for Applied Industrial Science and Technology, Japan researching phase change data storage materials in the Center for Applied Near-Field Optical Research. In 2011 he joined the Institute of Photonic Sciences, Spain as a Marie Curie Fellow where he investigated the use of tunable materials in photonics devices. Since 2012, Robert has held a position as Assistant Professor at the Singapore University of Technology and Design, Singapore where he formed the Advanced Chalcogenides Technologies & Applications Lab. His research interests are centered on chalcogenide materials, including methods to design their properties and their application in optical and photonics devices.Alexandra BoltassevaEditor-in-Chief, Optical Materials ExpressPurdue University
