Emeritus Professor of Physics at Arizona State University and a Fellow of the American Physical Society (APS). He is principal architect of Geometric Algebra and Calculus as a unified mathematical language for physics and engineering. He has also developed a Modeling Theory of Cognition and Instruction with extensive applications to STEM education. In recognition of this work he was designated Foundations of Physics Honoree in 1993, awarded the 2002 Oersted Medal by the American Association of Physics Teachers, the 2003 Education Research Award by the National Council of Scientific Society Presidents, and the 2014 Excellence in Physics Education Award by the APS.

Professor of Astrophysics and Cosmology in the Cavendish Laboratory and Deputy Head of the Kavli Institute for Cosmology at the University of Cambridge. His Ph.D. work was carried out at the Jodrell Bank Radio Observatory specializing in the Cosmic Microwave Background, which has been a major subject of his research ever since. He has also published extensively in several theoretical fields, including the application of new geometric techniques in physics, and statistical techniques in data analysis. Geometric algebra has formed a major component of his work since the early 1990s, and he is the co-author of the treatise Geometric Algebra for Physicists and several papers applying the methods of geometric algebra to topics in astrophysics, cosmology and gravitational theory.

Leo Dorst is with the Informatics Institute at the University of Amsterdam. He received his MSc and PhD in the Applied Physics of computer vision from Delft University, and started his work on geometrical issues in robotics at Philips Laboratories, NY. His passion is geometric algebra and its applications to computer science. He is coauthor of the treatise Geometric Algebra for Computer Science (2009). He is currently participating in the H2020 project GRAVITATE, contributing efficient mating of 3D scanned broken archaeological artifacts.

Joan Lasenby is a Reader in Signal Processing in the Cambridge University Engineering Department (CUED). Her research interests are engineering applications of Geometric Algebra, image and video analysis, non-invasive monitoring for medical applications, data analysis for sport and 3D reconstruction from multiple sensors. She is a co-founder of a computer graphics company specialising in real-time lighting for video games (recently sold to ARM) and a company providing solutions for non-invasive respiratory monitoring. She has supervised over 30 PhD/MPhil students, written over 100 journal and conference papers, is named on four patents and has organised a number of international conferences. She has ongoing collaborations with Medimmune, NHS England, the English Institute of Sport and a number of industrial companies. Her first degree was in Mathematics and her PhD was in Radio Astronomy (both from the University of Cambridge). She is a Fellow and Director of Studies at Trinity College, Cambridge.
