short biography

Andrew Holmes received the BA degree in natural sciences from Cambridge University in 1987, and the PhD degree in electrical engineering from Imperial College London in 1992. He was a Research Associate in the Department of Electrical and Electronic Engineering, Imperial College London from 1991 to 1993, after which he took up a joint Research Fellowship in Microengineering with Imperial and the Rutherford Appleton Laboratory. In 1995 he was appointed to a Lectureship at Imperial College London, where he is currently Professor of Micro-Electro-Mechanical Systems (MEMS), Director of Postgraduate Studies, and Deputy Head of the Optical & Semiconductor Devices Group. Dr Holmes has worked on a range of topics in optical signal processing, integrated optics and MEMS, and has published around 150 journal and conference papers in these areas. His current research interests include micro-power generation by energy harvesting, power conditioning for energy harvesters, tribology of micro-scale mechanical systems, novel micro-assembly techniques, and laser processing for MEMS and electronics manufacture. He is a co-founder and director of Microsaic Systems plc, an Imperial College spin-out company started in 2001 to exploit Imperial College MEMS research. The company, which has developed a bench-top mass spectrometer based on MEMS technology, was admitted to AIM in 2011.
