Harrison Lees is a PhD Student 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. Under the supervision of Assoc. Prof. Withawat Withayachumnankul and Dr. Daniel Headland (Osaka University), Harrison is investigating various integration strategies for all-silicon microphotonic circuits to further the effective-medium clad waveguide platform being developed by colleagues at the Terahertz Engineering Laboratory.
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".
