Profile

Professor Geof Tomlinson is currently the Director of the Dainton-Boucher Institute (the DBI). This is a new University of Sheffield initiative to create a stronger research footprint in Singapore. The Institute will act as a hub for research developments in Singapore and will initially focus on the fields of Aerospace Engineering and Advanced Manufacturing.

Prior to this, from 2001-2008, Professor Tomlinson was the Pro-Vice Chancellor for Research and from 1995 to 2001, he was the Head of Department of Mechanical Engineering. Over the period 1998 to 2007, he was also the Director of the Rolls-Royce University Technology Centre in Materials Damping Technologies, a field of research in which he is still very active. He was a member of the Main Panel G (Engineering) and Chair of the Sub-Panel for the General Engineering for the RAE 2008. He has continued working with the Higher Education Funding Council (HEFCE) as a member of the Expert Advisory Panel for the Research Excellence Framework (REF).

Professor Tomlinson´s current research interests are in the fields of novel damping materials and non-linear structural dynamics. He is a Fellow of the Royal Academy of Engineering, the Royal Aeronautical Society, the Institution of Mechanical Engineers and a Chartered Engineer. He holds several external professorial positions, acting as an advisor to the European Institute for Innovation and Technology, several National and International Universities, HEFCE, EPSRC and is a member of the National Technical Committee on Aerospace Materials and Structures. He is on several editorial boards and acts as a reviewer for international journals.

Geof is a member of the Leonardo Tribology Centre.

Areas of Research

Geof´s work is concerned with all aspects relating to the vibrations of engineering structures. A key research area relates to the reduction of vibration levels via the introduction of novel damping technologies. Geof works closely with the aerospace industries and has worked with Rolls-Royce (both Derby and Bristol) for over 30 years.

Damping topics include: polymeric and viscoelastic materials, granular materials, fibrous materials, functional damping coatings. Finite element methods are used to characterise and design damping materials for a wide range of engineering applications. More recently, Geof is involved with techniques for detecting biological signals (eg. Heartbeats), with applications in a range of security and `people at risk´ areas.
