Research Interests
My research focuses on animal behaviour and welfare, particularly understanding how farm animals respond and adapt to environmental, social and management challenges. I am interested in integrating behavioural, physiological and health indicators to assess both positive and negative welfare and to understand individual variation in animals’ responses to stressful or challenging events. A particular focus of my research is the development and evaluation of practical, evidence based approaches to improve the welfare and resilience of animals within commercial livestock systems. My work has primarily involved cattle and includes research on early life management, human animal interactions, behavioural and physiological responses to stress, and the use of appeasing pheromones as potential welfare interventions. I also have a strong interest in quantitative approaches to animal behaviour and welfare research and the application of robust statistical methods to longitudinal animal data.
Scientific Inspiration
My scientific inspirations include Nina von Keyserlingk and Temple Grandin. I particularly admire Nina von Keyserlingk’s work in farm animal welfare and her use of behavioural science to understand animals’ needs, preferences and experiences. Temple Grandin has also been highly influential in demonstrating how an understanding of animal behaviour can be translated into practical changes in livestock management and handling. Their work reflects an approach I value in my own research: combining rigorous animal welfare science with practical solutions that can make a meaningful difference to animals within commercial farming systems.

Growing into the herd: can delayed social integration improve resilience and welfare in first lactation dairy cows?

Project Outline
Premature loss of replacement heifers is an important welfare, economic and sustainability challenge for the dairy industry. The transition into first lactation is particularly demanding: heifers experience calving, onset of lactation, dietary and management changes, adaptation to milking and, commonly, integration with unfamiliar multiparous cows within a short period. Primiparous cows are still growing, are generally subordinate to mature cows and may experience greater competition and displacement from resources. Social stress at this physiologically demanding stage could therefore affect welfare, energy balance, health, fertility and productive longevity.
This project will investigate whether delaying social integration with multiparous cows until later in first lactation improves the welfare and biological resilience of primiparous cows, while minimising disruption to resident mature cows. Replacement heifers will experience contrasting social management strategies and will be followed longitudinally through the transition into first lactation and integration with the mature herd.
Behavioural and social responses will include agonistic and affiliative interactions, displacement, feeding and lying behaviour, rumination and activity. These will be integrated with physiological indicators of stress and energy balance, health, milk production, reproductive performance and retention. Intensive measurements around integration will characterise acute responses, while longer term monitoring will determine whether integration timing influences subsequent health, fertility, productivity and retention. The project will establish whether delaying integration offers a practical management strategy to improve welfare and productive longevity in dairy cattle.
