Dr Bozena Zaleska


Dr Bozena Zaleska has completed undergraduate studies at the Faculty of Animal Bioengineering at University of Warmia and Mazury in Poland, and continued her education there concentrating on Animal Breeding and Utilisation. This sparkled interest in animal reproduction and breeding, which lead to a PhD research exploring the effects of yeast on sheep reproduction and lamb growth and meat quality.

Before coming to RAU in 2020, she was a Lecturer at Writtle University College and Moulton College.
