Nicholas Hawker - Co-founder & Chief Scientific Officer

Nicholas Hawker

Co-founder & Chief Scientific Officer

Nick’s research into fusion began in 2007 as part of his masters thesis, where he worked at the University of Oxford with Yiannis Ventikos. This work continued into a DPhil, where he performed hydrodynamic simulations of shock-driven cavity collapse. These simulations showed that cavity collapse leads to inertial confinement of the gas inside the cavity and revealed that extreme states of matter could be reached, possibly entering the regime for fusion.

To explore the concept of energy generation via this process, Nick and Yiannis co-founded First Light Fusion Ltd in 2011.

Nick also spent three years tutoring at Lady Margaret Hall during his studies. After finishing his DPhil in 2012, Nick joined First Light Fusion as CEO and CTO. In 2024, Nick was appointed Chief Scientific Officer and continues to oversee the technical vision of the company.

With more than two decades of diverse industry experience and over 15 years supporting UK university spinouts in senior roles, David brings to First Light deep hands-on experience and an alternative perspective from his extensive career. Tech start-ups are a natural fit for his skills; his business insight and focus on pragmatic outcomes allow his teams to make hard things possible.

After early career roles in engineering, chemical, FMCG, and enterprise software businesses, David made the transition to the Oxford spinout scene when he joined T+ Medical in 2006. There he held senior financial and operational positions including Interim CEO. After several roles and a merger, he moved on by setting up Right Brain Finance, a consultancy offering financial direction and business support to a wide range of entrepreneurial tech businesses across South-East England. Despite considerable success (with VC backed clients in sectors that ranged from Sports Health Tech to Industrial Biotech), David found it frustrating to only “advise” but not be able to “do”. He therefore took the opportunity in 2015 to join the board and then to take the executive role of CFO at First Light Fusion, one of the businesses he had supported as a consultant.

David has been a CIMA MIP, and holds a BA in Geography and a MSc in Psychology.
