Mike Evans

Research & Innovation Manager


Mike is a Chartered Mechanical Engineer with a PhD in the tribology of polymer-steel spur gear contact mechanics. He has spent his career in a variety of design roles in nuclear, space and industrial equipment manufacturer organisations. He now leads a small team of research engineers at Rotork in Bath.


Rob Frazer

Senior Engineer

Design Unit

Newcastle University

Rob Frazer is a senior engineer and worked for Design Unit at Newcastle University for 35 years.  That has proved more than enough time for his mistakes to catch up with him. 


Rob leads the UK’s National Gear Metrology Laboratory (NGML), is chair of BSI’s gear committee MCE/5 and a member of the ISO gear accuracy committee (ISO TC60 WG2). 


He provides technical support to the British Gear Association’s Technical and Research Management Committee (TRMC) and helps deliver the BGA’s Knowledge Transfer programme.

Paul Newberry

Aerospace Consultant


I have 40 years experience gained in three major aerospace companies. I started my career as a technician apprentice with Thales (Taunton) and became a Chief Design Draughtsman where I was responsible for the management of 12 staff. I joined Rolls Royce in Bristol and studied a part time degree to become a Senior Stress Engineer responsible for the design and analysis of major gas turbine components. In 1998 I joined Leonardo Helicopters as a Stress Engineer in Transmissions Design, I have willingly took on additional responsibility and became a Chief Project Engineer directly responsible for the design and analysis of all Lynx, Apache and Seaking Transmissions design issues and the associated Design staff. I was responsible for reporting and communicating to senior management, setting departmental budgets; setting strategies for new products and new process.
