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.
