Harrison Lees is a Post-Doctoral researcher at The University of Adelaide whose focus is directed at developing terahertz integrated circuits to realize high-speed communication, imaging and, spectroscopic systems in the terahertz band. Harrison is currently working under an NISDRG funded project seeking to develop sensitive terahertz radar systems for probing semiconductor devices.In 2024 Harrison completed his PhD under the supervision of Prof. Withawat Withayachumnankul and Dr. Daniel Headland at the University of Adelaide. Harrison's thesis entitled "All-dielectric Terahertz Waveguides, Devices, and Techniques", focused on advancing the technical readiness of terahertz technologies by developing various waveguides, passive devices, and investigating techniques for reducing the cost and complexity of systems. For this work he was awarded a Dean's Commendation.In 2020 Harrison completed a double degree program at The University of Adelaide and was awarded a Bachelor of Engineering (Electrical & Electronic) with First Class Honours, along side a Bachelor of Finance. For his final year project "All-Silicon, Low-Crosstalk Terahertz Waveguide Crossing", Harrison was awarded "Ingenuity - Best Sensing and Security Exhibit Winner", "The DSTG Surveillance Systems Undergraduate Prize" and "The Executive Dean's Recognition of Academic Excellence".
