Dr Yanli Qi

Yanli joined the CORNERSTONE team in November 2020, working on chip fabrication and testing. She previously worked on Silicon Photonics Bio-Chemical Sensors in the Optoelectronics Research Centre (ORC) at Southampton University as a PhD student. The focus of her studies were on the chip designs of silicon on insulator waveguides with a microfluidic channel. Through this, she gained experience with integrated silicon on insulator waveguides, germanium on silicon waveguides and suspended silicon waveguides for sensing applications. Before PhD, her Master’s degree project focussed on developing a device to measure blood glucose levels through analysing the changing signal levels in a resonant microwave cavity with varying concentrations of glucose. Her research interests are in the integration of engineering and medical instruments in Photonic Systems Circuits & Sensors. She possesses a great enthusiasm for recognising and exploring the cutting-edge technologies for sensors and the development of medical instruments for diverse applications.

Dr Vadivukkarasi Jeyaselvan

Vadivukkarasi Jeyaselvan received her B.E. in Electrical and Electronics Engineering in 2011 and M.E. in VLSI Design from Anna University, Tamil Nadu, India in 2014. From 2014 to 2020, she was working towards her PhD in the design and development of electro-optic modulators in silicon-on-insulator platform for telecommunication. She joined silicon-photonics group at ORC, University of Southampton in 2020. Her research areas include silicon photonics, optical modulators/detectors, wavelength selective devices, design and fabrication of integrated photonic devices. She has authored and co-authored over 15 journal and conference papers.

Professor Roger Webb

Roger joined the Department in 1983 as a Research Fellow with the SRC (as it was then - interesting how the EPSRC has gained letters over the years) Surrey Ion Beam Centre. He was employed to look after the computing facilities associated with the research group - a single pdp11, about half of the computer "power" in the department in those days.

Before this he had spent 3 years as a post doc at the Naval Postgraduate School in Monterey California, making Molecular Dynamics Studies and Computer Animations, which is still the main area of his research activities. He did his PhD work in the Electronic & Electrical

Engineering Department of the University of Salford, on the Mathematical Modelling of Atomic Collisions in Solids.

He was made a Lecturer in the Department in 1986, promoted to Senior Lecturer in 1993 and then to Reader in 1997, reaching the dizzy heights of Professor of Ion Beam Physics in 2002. He is the current Director of the Surrey Ion Beam Centre.

He has performed research at Penn State College and the Chinese University of Hong Kong.

Sarah-Jane Bridger

Sarah-Jane Bridger is the Project Administrator for the Cornerstone team. She has previously worked for the Child and Adolescent Mental Health Services, Hampshire Constabulary and The University of Bath. Sarah received a BA in Fashion Journalism in 2013. Outside of work Sarah enjoys yoga, live music and has dreams of visiting all seven continents. 

Professor Jonathan England

Jonathan joined the Surrey Ion Beam Centre as Professor of Ion Implantation Technology in March 2017 after spending 25 years in the semiconductor equipment industry, 21 of those in ion implantation with Applied Materials and Varian Semiconductor Associates. He held senior management positions in the UK and USA leading the technical development of implantation equipment and collaborated with universities and companies in USA, China, Korea, Australia, Europe and UK in research on implantation based processing of advanced memory devices, ultra-shallow transistor junctions, solar cells and solar glass. He holds over 30 granted US patents in the field of ion implantation.

Jonathan has been an industrial mentor for the Surrey University Ion Beam Centre Steering Committee, European SPIRIT Programme (Support of Public and Industrial Research using Ion Beam Technology), and the “Amorphous Chalcogenide-Based Optoelectronic Platform for Next Generation Optoelectronic Technologies” with Surrey, Southampton and Cambridge Universities.

After obtaining his degrees in physics and nuclear physics at the University of Manchester, Jonathan spent his early career working with ion beams in isotope mass spectrometry at Vacuum Generators and then Columbia University.
