John Catsoulis lives under the tropical sun in Brisbane, Australia. He has a Bachelor of Science with Honors (Griffith University) with a triple major in quantum physics, electronics and mathematics, and a Master of Engineering (La Trobe University) in specialized computer architectures. He has been responsible for the design of more computer systems than he can remember, from tiny finger-sized machines to multi-processor compute engines. Corporations and government bodies around the world have used his designs and software. John has also taught the dark arts of computer architecture and design at several Universities. He is currently conducting research at the University of Queensland into fault-tolerant reconfigurable computers for spacecraft avionics. When not slaving over a hot microprocessor, John enjoys hiking and camping, wildlife and landscape photography, fishing, dabbling in permaculture, cooking Indian and Mediterranean food, and playing model trains with his nephews, Andrew and James.
