Dr Anna Hoerder-Suabedissen

Stipendiary Lecturer in Physiology



I completed a BSc in Natural Sciences at Lancaster University, before moving to Oxford to undertake an MSc in Neuroscience. There, I also obtained my DPhil in Developmental Neuroscience, and have worked as a post-doctoral researcher in different labs in the Department of Physiology, Anatomy and Genetics since. I have been a lecturer in Neuroscience at Keble College and Trinity College.


At St John's, I mainly teach for the final honours school theme 'Wiring up the brain', as well as contributing to the synoptic and critical appraisal paper teaching for FHS students.

Research Interests

My research interest is in early brain development. In my current work, I determine ways to identify the claustrum in developing mouse brains. The adult claustrum is widely interconnected with most part of the cortex, and single neurons often project to many different cortical regions. Finding ways to delineate the claustrum during development has helped us to determine when claustrum neurons first form connections to other parts of the cortex. This occurs relatively late during mouse brain development, and the timing may be relevant to the emergence of particular features of sleep.
