About us:

Dr Polly Taylor graduated from Cambridge, worked in general practice and then returned to academia, becoming Chief of Anaesthesia at the Animal Health Trust in the 1980s. She then returned to the Cambridge Vet School, becoming Reader in Anaesthesia in 2000. In 2008 she co-founded Topcat Metrology Ltd alongside her work as a freelance consultant, with work ranging from clinical aenasthesia and teaching to drug registration and research. She has published numerous papers, particularly relating to horses and cats, and is co-author of “The Little Red Book”, the Handbook of Equine Anaesthesia.

Dr Michael Dixon has a degree in Mechanical Engineering and a PhD in Metrology from the National Physical Laboratory (where he developed the first dynamic force standard in the world). He now has thirty years experience of measurement in unusual environments including the Polar icecap, the side of an oilrig and geo-stationary orbit. In 1998 he developed, with Polly Taylor, a thermal threshold testing device for cats. This business grew and in 2008 they founded Topcat Metrology Ltd, the only supplier in the world of wireless thermal and mechanical nociceptive testing systems. He is the prime author of numerous papers, of 8 published patents and of several current patent applications relating to the MouseMet EvF transducer and testing environment.
