Dr Yuvaraja Visagathilagar has over 27+ years of extensive expertise and experience in academia, research, and industry. He graduated with Bachelor of Engineering in Communication Engineering and Doctorate in Engineering (with a highly prestigious scholarship from the Australian Government) in 1996 and 2003 respectively from RMIT University, Melbourne Australia. His dissertation was in “Narrow-band Optical Modulator on Lithium Niobate” for telecommunication applications but it can be applied for other transceivers applications. In research and industry, he has contributed to over 40+ peer-reviewed international journals and conference pubications. He has visited and presented at universities in USA (i.e. UCLA and UCSD), Peregrine Semiconductor Corporation and in Japan (i.e. Science and technology Organisation).He has collaborated with Defence Science Technology Organisation (now DSTG) in Australia where he has contributed in the design, fabrication, packaging and testing of “High-Speed Lithium Niobate Optical Modulator” including documentation of processes for quality certification (ISO 9001) and flip-chip packaging of narrow-band optical modulators on Lithium Niobate and Ceramic materials. He has extensive academic teaching as a lecturer and post-doctorate research fellow in Photonics, Fibre Optics & System, RF System, and Integration where he was involved in research of novel design of narrowband optical modulators. In early years, his research has been in Narrow-band Lithium Niobate Modulators but also in finding a solution for packaging of optoelectronic devices (i.e. ceramic and Silicon materials). During the collaboration, he worked with sub-contractors in system integration and packaging of the modulator devices in hermetically sealed packages for defence applications. In 2006, he joined “Future Fibre Technologies Ltd” who are the global leading organisation in optical sensing technologies and has extensive experience over 9 years in optical sensing. He was a senior manager and held positions as Senior Fibre Systems Engineer, R&D Team Leader and Applications Engineering Manager where he contributed in the company products enhancements and novel products design. He has contributed to 2 patent solutions for novel systems in optical fibre sensing and contributed to over 110+ reports with fellow colleagues and R&D teams (not published due to commercial-in-confidence). From July 2016 to March 2018, he was a Senior Academic at RMIT University for postgraduate and undergraduate courses in Electrical Engineering Analysis using Matlab, Electronic Engineering, Radar technologies, Communication systems, Optical/Photonic Engineering, Microwave Circuits & System and Advanced Mathematics for various program levels (or years). He contributed to the development teaching materials of a core course in Optical Fibre Systems and Networks for Bachelor and Master’s Program including supervising for over 10+ projects in undergraduate and postgraduate students with a minor thesis. Since April 2018 to June 2020, he is a Senior Academic with the Department of Electrical and Electronics Technology & Engineering, Applied Engineering College (AEC), Riyadh, Kingdom of Saudi Arabia which is affiliated with Lincoln College International and University of Hull, UK with accreditation of Colleges of Excellence by the Government of Kingdom of Saudi Arabia where he is undertaking teaching in Electrical and Electronics technologies & principles for various Bachelor level program. He has been a senior supervisor for over 30+ projects demonstrated and a minor thesis. In July 2020, he is a researcher undertaking photonics research into reservoir computing and senior academic in lecturing a topic in Optical Fibre Communication Systems, Digital Electronics projects using Altium to design & built a Digital Oscilloscope and Microwave/RF Systems with ©Cadence and Electronic Engineering at the University of Melbourne (Australia) and in January 2021, he joined RMIT University as a researcher and senior academic undertaking research in optical fibre systems and transmission with high-level multi-disciplinary engineering team. Since January 2022, he joined QinetiQ Australia as a Principal Engineer (Senior RF/EMI/EMC Systems Engineer) as a Design and Advisory role providing his expertise & experience in defence and government projects with key interest in Microwave/RF/Radar Communication Engineering, coherent detection optical sensing for pipelines, undersea exploration, seismic detection and temperature sensing, high-speed and narrow-band optical modulators. Recently in March 2023 was awarded with accreditation & certified with the Engineers Australia (EA) Chartered Professional Engineering (CPEng) and in the National Engineers Register (NER), APEC Engineer and IntPE(Aus). He has a distinguished professional engineering career, he is an active Senior Member of the IEEE for over 28+ years’ service where he is the Chair of the Victorian IEEE Electron Devices & Photonics Society Joint Chapter and representative in the Section Committee, Australia from 2017 He is a active member of IEEE where he is a key volunteer for the Senior Member Elevation reference in Victoria, Australia (or globally), Member of OSA, SPIE, AP-MTT, AIP, AOS, BCS and certified in PRINCE2® & system engineering. He is in various editorial boards for peer-reviewed international journals and key reviewer for many international scientific journals and conferences. He has presented at various international and local conferences as Plenary, Keynote, Invited and has been asked to provide a welcome talk at conference. Other interests include and on-going, provides professional engineering consultancy to organisations locally and globally but passionate about teaching high school students from year 7 – VCE & other states in all Mathematic, Physics, System Engineering and Technology.
