Following research into Wave Power at the University of Edinburgh, Niall joined Artemis in 1999. There he developed the first Digital Displacement machine for driving the wheels of a vehicle, including associated mechanisms, ultra-fast solenoid valves and embedded software.
He wrote his PhD on this technology in his spare time, while building the relationships with industrial partners to commercialise it. As Technical Director, he led the team which developed the control systems for Artemis's hydraulic hybrid systems, including a series-hybrid BMW saloon demonstrator. Following the acquisition by MHI in 2010, he led the development of the control system of the 7MW offshore-wind hydraulic transmission, and took over as Managing Director in 2013. He is inventor of over 50 patents, and received the 2015 MacRobert Medal from the Royal Academy of Engineering.
