Staff profile

I am the founding director of the Durham University Space Research Centre (SPARC) a UKRI Future Leaders Fellow and a Professor in the Centre for Advanced Instrumentation (CfAI), Durham University, UK. 

SPARC is a new research centre connecting experts across space technology, operations, governance and security. We are founded on the principle of open, rigorous and independent research to grow the capacity and capabilities of space applications while protecting the space environment for present and future generations. Our vision encompasses not only the pursuit of cutting-edge technologies but also the holistic understanding of space and its broader societal, ethical, and environmental impacts. Through responsible, multi-disciplinary research, including novel sensors, environment modelling, machine learning, governance and operations, we aim to address the complex challenges and opportunities of space exploration.

In the CfAI, I lead the free-space optics group, an ESA affiliated lab (ESA_lab@Durham), studying how light travels through the Earth’s atmosphere. Initially this focussed on instrumentation for astronomy, building the scientific equipment that enables astronomers to use large ground-based telescopes to study planets orbiting distant stars, how galaxies form and evolve and even the nature of dark matter in the universe. More recently I have focussed on exchanging technology and techniques from astronomy into emerging sectors such as free-space optical communications (enabling global high-bandwidth and secure connectivity) and space surveillance and tracking (enabling the sustainable exploitation of space).

I have a reputation as a world leader in the field of free-space optics built on a foundation of regular innovation in the field. This has led to many systems and tools which are in current and continuous operation around the world by researchers, aerospace agencies, government agencies, and industry.
