Individual variation of laying hen movement and location patterns within a commercial aviary

During my B.Sc. studies of Cognitive Science at the University of Tuebingen, Germany, I discovered my passion for avian behaviour. Following my graduation in 2017, I joined the master's programme of the Neural and Behavioural Sciences at the Graduate Training Centre of Neuroscience in Tuebingen. For the programme, my roles included an internship in the laboratory of Prof. Dr. Frank Schaeffel's laboratory examining contrast sensitivity in chickens and an assistantship in Prof. Dr. Volker Franz Experimental Cognitive Science laboratory, where I focused on computational neurosciences. For my M.Sc. thesis, I assessed negotiation strategies of ravens when dealing with inequity in a cooperation task, at the Cognitive Biology Department of the University of Vienna under the supervision of Prof. Dr. Thomas Bugnyar.
I began my Ph.D. at the University of Bern in the Fall of 2019 under Dr. Mike Toscano with a focus on how movement patterns of individual laying hens in large groups relate to animal health and welfare.
