Tom is Executive Director of Xelect Ltd, a spin-out company from the University of St Andrews. The core business of Xelect is the development of genetic markers for aquaculture broodstock selection. Markers for superior fillet yield, flesh quality and faster growth in Atlantic salmon and Nile tilapia are available for licensing worldwide.

Xelect has a strong pipeline of markers in development for other traits and species such as rainbow trout, barramundi and tuna. We also offer a comprehensive range of genetic and analytical laboratory services the industry. 

Tom is co-inventor of the Xelect genetic markers and of the tensile method of texture analysis. He has broad experience in marine biology, aquaculture and molecular biology. Tom obtained a PhD from University of St Andrews in 2011, with a thesis entitled “The genetic basis of flesh quality traits in farmed Atlantic salmon”.
