Professor Alwyn J. Seeds holds the B.Sc. degree in Electronics, the Ph.D. degree in Electronic Engineering and the D.Sc. (Eng.) degree, all from the University of London. From 1980 to 1983 he was a Staff Member at Lincoln Laboratory, Massachusetts Institute of Technology. He was appointed Lecturer in Telecommunications at Queen Mary University of London in 1983. In 1986 he moved to UCL where he is currently Professor of Opto-electronics and Head of the Photonics Group. Professor Seeds is Chairman of the IEE Photonics Professional Network, a Past-Chair of the IEEE International Topical Meeting on Microwave Photonics, Steering Committee and has served as the Conference Chairman or Technical Programme Committee Chairman for many international conferences. He is a co-founder of ZinWave Inc., a wireless technology company. He was elected an IEEE Fellow in 1997 for his contributions to the development of microwave photonic devices and systems and a Fellow of the Royal Academy of Engineering in 2003.

Professor Seeds is author of over 250 papers on microwave and opto-electronic devices and their systems applications and presenter of the video "Microwave Opto-electronics" in the IEEE Emerging Technologies serie
