The British Society of Animal Science (BSAS) is delighted to announce the appointment of  Stefan Yerby as a trustee of the Society.

Stefan is currently completing his PhD at the University of Galway, where his research focuses on dairy cattle nutrition and sustainability, aiming to improve dairy efficiency while reducing environmental impact. 

Stefan is driven and committed to sustainable livestock systems; having spent a decade in industry before becoming research active across the UK and Canada.

Alongside his doctoral studies, Stefan recently joined the Farming Science Team in the Department for Environment, Food & Rural Affairs (DEFRA), where he continues to contribute to sustainable agricultural systems, particularly in areas relating to greenhouse gas mitigation.
His appointment as a trustee was formally confirmed at the BSAS Annual Conference AGM, held in Galway in 2024.

Commenting on his appointment, Stefan said:

“It is a real honour to join the BSAS Board of Trustees and stand alongside some of the most inspirational individuals in animal science. The Society has played a key role in supporting my development as an early-career researcher, and I’m excited to give back by helping BSAS continue its work in promoting high-quality animal science and supporting the next generation of researchers."

Welcoming the appointment, BSAS President Helen Warren added:

"Stefan’s drive, insight, and passion for sustainable livestock systems will be a great asset to BSAS. We are particularly pleased to welcome a trustee who can represent and inspire early-career scientists at such an important time for the sector."
