BEST Award

Background Information
NNL is committed to developing technical and scientific experts within the lab. As part of the process it is imperative that we recognise talent within the business and provide an environment in which technical excellence can flourish. Excellent science is fundamental to the success of the NNL and should be celebrated. The aim is to promote excellent science within the lab, and to promote NNL's scientific achievements externally.

As part of this strategy, in 2012 NNL launched an Award for the Best External Scientific or Technical (BEST) publication, with the BEST Award winner receiving the Lawrence Medal (named after former NNL Managing Director, Mike Lawrence).

Any external publication with an NNL employee as a principal author will be eligible for the award. The BEST Award runs by calendar year; The BEST Award 2014 was presented at the NNL Technical Conference on May 1st 2014. Details for next year will be added to this page once they have been confirmed.

BEST Award for 2013 papers
There were 14 submissions for the Best External Scientific or Technical (BEST) publication award this year. Each paper was assessed by a short listing committee consisting of the Chief Technologists (Mike Angus, Anthony Banford, Jonathan Hyde, Richard Stainsby) the Chief Engineer (Richard Taylor) and Laboratory Fellow (Nick Smith). A short list of 6 were selected on the basis of
• the technical and scientific content,
• the coherency of argument,
• the innovation and impact of the science.

The 6 finalists were Mike Carrott, Colin Gregson, Martin Metcalfe, Paul Ramsey, Howard Sims and Guy Whillock. This year the judging panel was chaired by Graham Fairhall, with Eann Patterson (Liverpool University) as an external academic, and Senior Fellows Joe Small, Colin English and Kevin Hesketh representing each of the business directorates. Many congratulations to the winner, Howard Sims, who received the Lawrence medal for the BEST Award at the inaugural NNL conference held on the 1st of May.
