Our research will provide fundamental insights into the epigenetic mechanisms that underlie ataxia, developmental delay, autism, intellectual disability and executive dysfunction.
Mutations in CHD7 cause CHARGE syndrome, a syndrome that affects the development of multiple organs in the body. We have identified several critical roles for CHD7 in development of the cerebellum and our work has implicated CHD7 in cerebellar hypoplasia and medulloblastoma, the most common paediatric brain tumour.
Mutations in CHD8 cause autism, macrocephaly and intellectual disability. We have identified key, dosage-dependent roles for CHD8 in regulating autism-associated genes and brain growth.
We are taking novel, unbiased approaches to identify cell type-specific distal regulatory elements that control and fine-tune the expression of key neurodevelopmental genes in the cerebellum, in order to identify non-coding substrates for neurodevelopmental disorders.
Our research has been funded by the Medical Research Council, Simons Foundation Autism Research Initiative (SFARI), CHARGE syndrome Foundation and the Anatomical Society.
Albert obtained his PhD from the University of Cambridge and underwent post-doctoral training at the National Institute for Medical Research (Mill Hill), Mount Sinai School of Medicine in New York, King’s College London and UCSF. His primary interest is to understand how deregulated cell signalling and gene expression results in congenital disease. His research has provided insights into the causes of developmental defects of the thymus, kidney, cardiovascular system and cerebellum. The current focus of his group is to uncover the function of chromatin remodelling factors in brain development and neurodevelopment disorders like autism.
Clinical Research Fellow (RVC and KCL)
Dani is a veterinary clinical research fellow, jointly funded by the Royal Veterinary College and King’s College London. After qualifying as a veterinary surgeon, Dani was awarded a highly competitive Wellcome Trust Integrated Training Fellowship for Veterinarians. She obtained her PhD and was board certified as a specialist clinical Neurologist. Dani’s research is focused on identifying novel genetic causes of neurodevelopmental disorders with cerebellar hypoplasia and understanding the mechanisms that control the specification and differentiation of GABAergic lineages in the cerebellum.
We are recruited a new Post-doctoral research associate to investiagte the function of chromatin remodelling factors in learning and memory. The PDRA will be based in the laboratories of Professors M. Albert Basson and Peter Giese. The aim of the project is to use a combination of mouse genetic approaches, sterotactic viral injections into the hippocampus, learning and memory and behavioural tests and molecular and epigenetic approaches to determine the functions of these factors in the adult brain and to determine if restoring function in the adult brain can rescue specific learning deficits.
PhD student (MRC DTP iCASE)
Shail will join the laboratory later this year after completing his MSci degree at UCL. His PhD work will focus on characterising specific deficits in histone methylation machinery in neurons in the aged hippocampus and asking if correcting these deficits can ameliorate age-associated cognitive decline.
This project is a collaboration between the Basson and Giese labs at KCL and an industrial partner, Merck, Sharp & Dohme.
PhD student (MRC Centre for Neurodevelopmental Disorders)
Rugile is a first year PhD student on her final rotation. Her aim is to characterise hippocampus-dependent learning deficits in a mouse model of a novel, recessive neurodevelopmental disorder to understand how the loss of histone demethylase activity results in intellectual disability.
PhD student (Wellcome Trust Neurologist-Immune interactions)
Andy is a first year PhD student on his final rotation. He is interested in understanding how epigenetic changes that accumulate over time affect neuro-immune interactions in the aged hippocampus.

Currently there are four main research areas in the laboratory:
Functions and mechanisms of CHD7 in cerebellar and frontal cortex development
Neurodevelopmental roles of CHD8 and associated chromatin remodelling factors
Unbiased approaches to identify distal regulatory elements in primary cerebellar granule neuron progenitors
