Dr Niall Caldwell – Managing Director

Niall joined Artemis in 1999, where he demonstrated the first vehicle propel transmission with Digital Displacement® technology – and wrote a PhD on the subject. As Technical Director, he led the team designing electronics, software and system simulation models, and inventing control systems for applications from hybrid vehicles to offshore wind turbines. Niall became Managing Director in 2013, and still retains a keen interest in technical matters.

In his spare time, he cleans up after his classic car, and invents strange electronic musical instruments.


Jeff Herrin Chairman Artemis Intelligent Power

Jeff Herrin – Chairman

Jeff joined Danfoss in 1998 and has held roles of increasing responsibility within Product and Systems Engineering. Prior to joining Danfoss, Jeff held research positions at NASA Langley Research Center and General Electric Corporate Research from 1993-98. Jeff completed his PhD in Mechanical Engineering at the University of Illinois at Urbana-Champaign in 1993. He has been responsible for the Artemis Danfoss relationship and strategic developments leading up to the formation of the current Artemis Joint Venture with MHI.

In his spare time, Jeff enjoys cycling, reading and travel.

Professor Win Rampen – Founder Director

Win was a founder of Artemis Intelligent Power and has overseen the firm’s growth since its creation in 1994 to today. He was Managing Director until 2013.

In 1978 Win began work with the pioneering wave power group at the University of Edinburgh led by Professor Stephen Salter. It was there he first encountered Robert Clerk and his Tri-link hydraulic pump – which was intended for the ‘Salter Duck’ power take-off system.

This led to designing advanced hydraulic machines that were applicable not only to waves but, also, other forms of renewable energy and conventional vehicle transmissions. Win led the project at the university and led the creation of Artemis Intelligent Power.

Win holds the Chair of Energy Storage at the University of Edinburgh and is a Fellow of the Royal Academy of Engineering, the RSE, the Institution of Mechanical Engineers and the RSA.

When there are no meetings to chair, many of Win’s happiest moments are spent in his workshop or driving a tractor at his loch-side paradise.

Dr Uwe Stein

Dr Uwe Stein – Technical Director

Uwe has worked at Artemis since 1996. As Technical Director, he manages the mechanical development of Digital Displacement® machines. He supervises twelve engineers, all of whom are involved in the design, testing and improvement of the core hardware, or in systems where it can be applied.

Uwe completed an engineering diploma in Germany and completed a part-time PhD at the University of Edinburgh in 2004, during which he developed some of the fundamental Digital Displacement® technology. He is passionate about improving the practical training of engineers and teaches a hands-on engineering design class at the University of Edinburgh.

Uwe has three children and enjoys doing outdoor activities with them. He loves sailing and runs the youth dinghy sailing group at Portobello on a voluntary basis.

Pierre Joly

Pierre Joly – Operations Director

Pierre first joined Artemis for a 6-month placement in 2001, after which he returned to France to complete his degree in mechanical engineering. Upon graduating in 2002 he joined Artemis and was initially involved with all aspects of Digital Displacement® valves and machines design and testing before managing his first £1million+ project in 2009.

He was appointed Operations Director in 2012 and his main responsibility is the overall planning, coordination and resource allocation for all projects. With a personal interest in performance and analysis, he enjoys setting up systems to improve team communication and efficiencies.

Pierre enjoys sports in his spare time and won the Touch Rugby European Championships representing Scotland in 2012 and 2014. He was also co-founder and head coach of one of the biggest clubs in Scotland from 2008 to 2016.

Alasdair Robertson – Commercial Director

Alasdair has a degree in Mechanical Engineering from Heriot Watt University and joined Artemis in 2005. He worked on several projects before becoming heavily involved in the series hybrid BMW development program.

Following from that, he worked on the multi-MW wind turbine transmission and was heavily involved in due diligence work prior to acquisition in 2010. After the acquisition Alasdair moved into a commercially focused role dealing with application areas for the E-dyn 96 pump. He stepped into his current position in 2016.

In his spare time, Alasdair juggles family life, a woodworking tool habit and a yearning to restore old machinery while renovating his 200 year old house.
