Liam joined the JCSDA in June 2024, coming from a position in NASA's Global Modelling and Assimilation Office (GMAO), where he worked on model linearization. Liam's background is in applied mathematics and software engineering, and he has previously worked on problems in motion capture technology and additive manufacturing. Prior to pursuing a more academically oriented career, Liam served for nearly a decade as a paratrooper in the British Army, and is likely one of very few paratroopers to have jumped from an aircraft with mathematics textbooks in their equipment. When not working, Liam enjoys many outdoor activities, including hiking, climbing, kayaking, and skiing.
