Dr. Keating has been working with photonic device/systems, MicroElectroMechanical Systems (MEMS) and advanced semiconductor materials related to engineering for more than 20 years. After graduating with a Bachelor of Engineering with Honors (Electrical and Electronic) in 1989 from The University of Melbourne, he joined Telecom (now Telstra) Research Labaoratories in the wireless and later optical divisions. After 2 years and with the support of Telecom Research Laboratories, he undertook a Ph.D. investigating Photonic (fiber optic) communication networks, completing in 1995. In the following year he worked as a research fellow, demonstrating the highest bit-rate-distance product for a spectrum sliced communication system using novel feedforward noise cancellation methods. In 1996 he joined Nippon Telegraph and Telephony (NTT) in Japan where his work on high density, high speed all optical time demultiplexing resulted in several patents. In 1998 he joined Prof. John Bowers at University of California, Santa Barbara, and demonstrated the highest operating temperature (105°C) 1.55 µm Vertical Cavity Surface Emitting Laser (VCSEL). He joined an optical-MEMS startup company in 1999 (Calient Networks) as the fiber optics technology manager, directing a team of 7 consisting of Ph.Ds, mechanical, electronic and software engineers. He was responsible for developing high quality massively parallel fiber-collimators based on microlenses and designing optical systems/instrumentation based on MEMS, and then subsequently migrating these development into the manufacturing line. The tools and techniques he developed led to a high yield, high reliable product which could be assembled in the minimum time. He was invited to present this contributions at LEOS 2001 and has received 4 patents as a result of the work at Calient Networks. In 2004 he joined UWA where he has extended his work on MEMS, developing characterization techniques to evaluate the performance of MEMS microspectrometers operating in the infra-red. In 2007 he joined the School of Mechanical Engineering, advancing the Mechatronics program and work on MEMS.  He has taken the lead to teach mechanical engineering from Engineerign Dynamics to design, and currently teaches measurement and statistcial methods which can be applied to manufacturing processes.  His current research focuses on optical sensors based on MEMS and porous silicon materials, as well as the internet-of-things (IOT) technolgies (radio, antennas and engineering harvesting systems.)
