Caitlin Decina is a Master of Science student within the department of Population Medicine under the supervision of Dr. Olaf Berke and Dr. Alexandra Harlander. She grew up in Mississauga, Ontario, spending her time outside of school playing competitive softball. Caitlin completed her undergraduate degree in Biomedical Sciences at the University of Guelph. It was there that she developed an interest in the field of epidemiology. Caitlin’s desire to further her understanding of epidemiology led her to pursue a Master’s degree, joining the lab group of Dr. Alexandra Harlander, wherein her thesis involves participating in the epidemiological study of the risk factors for feather pecking in pullets and egg-laying hens. Despite decades of research, the mechanisms underlying feather pecking behaviour have yet to be fully elucidated. Through the careful design and administration of a questionnaire to be completed by egg farmers in Canada, the study aims to discern and assess putative risk factors for feather pecking and their interrelations. She is eager to tackle this prominent issue in the poultry industry and to assist in the improvement of hen welfare.
