K. Alan Shore received a BA ( MA) in mathematics from the University of Oxford, Oxford, U.K., and the Ph.D. degree from the then University College, Cardiff, Wales, U.K.

He was a Lecturer with the University of Liverpool from 1979 to 1983 and with the University of Bath, where he became a Senior Lecturer in 1986, a Reader in 1990, and a Professor in 1995. He was a Visiting Researcher with the Center for High Technology Materials, University of New Mexico, Albuquerque, USA, in 1987. In 1989, he was a Visiting Researcher with the Huygens Laboratory, Leiden University, The Netherlands. From 1990 to 1991, he was with the Teledanmark Research Laboratory and the MIDIT Center of the Technical University of Denmark, Lyngby. He was a Guest Researcher with the Electrotechnical Laboratory, Tsukuba, Japan, in 1991. In 1992, he was a Visiting Professor with the Department of Physics, University de les IllesBalears, Palma–Majorca, Spain. He was a Visiting Lecturer with the Instituto de Fisica de Cantabria, Santander, Spain, from 1996 to 1998, and a Visiting Researcher with the Department of Physics, Macquarie University, Sydney, Australia, in 1996, 1998, 2000, 2002, 2005, and 2008.

Prof. Shore has been a Program Member for several OSA conferences. In 2010, he held a Japan Society for the Promotion of Science Invitation Fellowship with the Ultrafast Photonics Group, Graduate School of Materials Science, Nara Institute of Science and Technology, Nara, Japan.

He was a Co-Organizer of a Rank Prize Symposium on Nonlinear Dynamics in Lasers held at the Lake District, U.K., in 2002. He cofounded and from 1987 to 2012 acted as the Organizer and Program Committee Chair for the International Conference on Semiconductor and Integrated Optoelectronics (SIOE), which is held annually in Cardiff, Wales, U.K. He chaired the Education and Training in Optics and Photonics conference held at the Technium OpTIC, Wales, 2009. He coordinated International Year of Light activities in Wales during 2015.He chaired the Science and Technology Committee of the National Eisteddfod of Wales, Bodedern, 2017.

He was awarded the Science and Technology Medal of the National Eisteddfod of Wales, Boduan, 2023

He is a Fellow of the Optical Society of America, the Institute of Physics, and the Learned Society of Wales for which he has served as a Council Member from 2012 to 2015 and from 2016 to 2024 and as its General Secretary from 2017 to 2023.

He is a member of the 2023/2024 UK Young Academy Membership Selection Committee.

He is the  Manager for Wales of the Alumni Association of the Japan Society for the Promotion of Science ( JSPS)
