Studying genome instability in neurodegeneration and ageing
Our mission is to improve the lives of people affected by brain disease through discoveries that protect brain health.
Understanding how neurons maintain their genomes throughout life.
We study genome instability in neurodegeneration and ageing, asking how neurons maintain their DNA and function throughout life. Alongside genetic screens and human cell and mouse models, our work on the naked mole-rat explores the biology of healthy brain ageing. Our aim is to understand what makes neurons vulnerable and what helps preserve brain health over time.
The Balmus Laboratory studies the DNA damage response in mature neurons. These long-lived cells face a particular challenge: protecting their genetic material over a lifetime.
We explore how neurons respond to endogenous genotoxic stress, how these responses change in disease, and which repair pathways influence neuronal survival.

Our approach combines CRISPR–Cas9 screening, human stem-cell-derived neuronal models and mouse models. We study Huntington’s disease, ALS and frontotemporal dementia, ataxia telangiectasia, and Parkinson’s disease. We also work on the naked mole-rat to investigate brain ageing and the mechanisms that may support long-term neuronal resilience.
