Brains frozen in time: vertebrate neural adaptations to invading land . The evolution of terrestrial animals from fish was one of the most significant events in our evolution, yet little is known about how the brain evolved during this transition. This project aims to investigate the major novelties acquired in the evolution of the early vertebrate brain in order to determine the functional reasons for such changes, as well as identifying the timing and environmental factors driving such changes ....Brains frozen in time: vertebrate neural adaptations to invading land .

How do researchers learn from and 'think with' non-human organisms? This project seeks to develop a comprehensive historical and philosophical exploration of the changing roles and understandings of research with organisms in 20th and early 21st century science. Advances in the content and technologies of the biological and biomedical sciences have resulted in new understandings of what we can know and learn from organisms, particularly with regard to human functioning, health, and well-being, yet we have no integrated scholarship examining these developments across a range of fields. This project seeks to produce useful scholarship relevant for humanities scholars, scientists, clinicians and policy-makers.Read moreRead less
Philosophical perspectives on psychedelic psychiatry. This project aims to develop a multi-level integrated theory of self-representation and self-awareness that explains the effects of psychedelic therapy in particular, and transformative experience in general. Psychedelic drugs can produce lasting psychotherapeutic benefits. The mechanism is a dramatic but temporary alteration to the ordinary sense of self, known as “ego dissolution”. However, fundamental questions about self-representation an ....Philosophical perspectives on psychedelic psychiatry. This project aims to develop a multi-level integrated theory of self-representation and self-awareness that explains the effects of psychedelic therapy in particular, and transformative experience in general. Psychedelic drugs can produce lasting psychotherapeutic benefits. The mechanism is a dramatic but temporary alteration to the ordinary sense of self, known as “ego dissolution”. However, fundamental questions about self-representation and its neural and cognitive implementation remain unresolved. In order to explain ego dissolution and its therapeutic effects, this project aims to integrate two theoretical approaches to self-representation situated at the intersection of philosophy and cognitive neuroscience, the predictive coding theory of brain function and the self-binding theory of self-representation. Such a framework has potential to anchor further interdisciplinary research and practical intervention in disorders of the self.Read moreRead less
