Dr. Michael C. Parker is a Research Fellow at the School of Computer Science and Electronic Engineering (CSEE) of the University of Essex. He completed his PhD studies in photonics and telecommunications (thesis title: Dynamic Holograms for Wavelength Division Multiplexing) at Cambridge University in 1996. In 1997, he joined Fujitsu Telecoms Europe (UK) and was with Fujitsu Network Communications, Richardson (TX, USA) from 2000 to 2003, and Fujitsu Labs of Europe until 2007. He was Visiting Professor at Essex University in 2004–2007. In 2007 he founded his technology consultancy company, Lexden Technologies Ltd. He has pioneered the application of thermodynamic principles to computation and communications theory, and advocated the first absolute energy efficiency metric (dBε) for ICT technologies. In 2019 he discovered the fundamental principles of Quantitative Geometrical Thermodynamics (QGT), which he has used to ab-initio calculate subatomic nuclei radii, nuclear decay rates, and to define Entropic Purpose across the complex time plane. He holds more than 20 patents and published over 170 papers in the peer-reviewed literature. Other interests include elastic optical networking technologies & architectures, converged wireless-wireline networking (5G/6G), novel microstructured optical fibres, and quantum cryptography & computation technologies. He is a Chartered Engineer, a Senior Member of the IEEE, and a Member of Optica, and the Institution of Engineering & Technology.
