Biography
Ruomeng studied Physics in China, receiving a BSc in 2008 and a MEd in 2009. He came to Southampton in 2009 where he obtained a MSc in Nanoelectronics and Nanotechnology in 2010 and a PhD investigating the confined nanoscale chalcogenide phase change material and memory in 2015. Following his PhD, Ruomeng was awarded an EPSRC Doctoral Prize fellowship in 2015 to start his independent research in functional chalcogenides and metal oxides with particular focus on application of novel non-volatile memory technologies (phase change memory and resistive switching memory) and thermoelectric (TE) materials and energy harvester. In 2018, he was appointed a lectureship in the Sustainable Electronic Technologies Group in the School of Electronics and Computer Science in the University of Southampton and was promoted to Associate Professor in 2023.
He was a Co-Investigator in a STFC grant (Selective Chemical Vapour Deposition for Production of Thermoelectric Micro-Generators for Energy Harvesting, £363k) for the development of thin film thermoelectric generators. He was also an investigator in a EPSRC program grant (ADEPT – Advanced Devices by ElectroPlaTing, £6.33m) which explores the state of the art of electrodeposition and device design at nanoscale in the areas of non-volatile memory (phase change and resistive memory), thermoelectrics, and infrared detection.
Ruomeng has published over 60 journal papers (Google Scholar) and delivered over 40 oral/poster presentations at national and international conferences. He is a regular reviewer of several journals from ACS, RSC and IEEE. He is a member of RSC and IOP and sits in the committee for the IOP Semiconductor Physics Group. He currently leads a team of 7 PhD students.
