Denize Atan

Denize Atan (Joint Chair) is an Honorary Consultant Ophthalmologist specialising in Paediatric and Adult Neuro-Ophthalmology at Bristol Eye Hospital and a Senior Lecturer at the University of Bristol. After completing her medical training at the Universities of Cambridge and Oxford, Denize went on to train in General Medicine and Ophthalmology before undertaking a Senior Clinical Fellowship in Paediatric and Adult Neuro-Ophthalmology in Birmingham, one of the largest Neuro-ophthalmology centres in the UK, with Mike Burdon, Tim Matthews, Andrew Jacks, Susie Mollan and Manoj Parulekar. Alongside her clinical training, Denize was awarded her PhD in Ocular Genetics from the University of Bristol under the tutelage of Amanda Churchill and Professor Dick with funding from the Wellcome Trust, followed by a postdoctoral Wellcome Trust Fellowship in Neurogenetics at Sick Kids Hospital in Toronto with Professor Rod McInnes. Her current research aims to investigate how genes regulate neurodevelopment, neurodegeneration and neuro-inflammation, as well as using novel methods in genetic epidemiology to determine the impact of environmental risk factors on common ocular diseases.

Mariya Moosajee

Dr Mariya Moosajee (Joint Chair) is a Consultant Ophthalmologist in Genetic Eye Disease at Moorfields Eye Hospital and Great Ormond Street Hospital for Children, and a Wellcome Trust Beit Prize Clinical Research Career Development Fellow and Senior Lecturer at UCL Institute of Ophthalmology. She graduated with First Class Honours in Biochemistry and Molecular Genetics BSc in 2000, Medicine (MBBS) in 2003, and was awarded her PhD in Molecular Ophthalmology in 2009 all from Imperial College London. Her current clinical focus is providing a genomic medicine service for children and adults affected with all forms of genetic eye disease including congenital eye defects and inherited retinal dystrophies. She undertakes detailed clinical studies to understand the natural history of retinal disease to identify accurate outcome measures for clinical trials. Dr Moosajee also leads her own research group at the UCL Institute of Ophthalmology and her specialist interest is understanding the molecular basis of ocular maldevelopment and inherited retinal dystrophies, using zebrafish disease models and human induced pluripotent stem cell derived retinal cells. Through dissecting the molecular and cellular pathways of disease, Dr Moosajee and her team have identified potential therapeutic targets and developed treatment strategies, including nonsense suppression therapy for inherited retinal diseases, which is translational and applicable to a wide range of genetic eye disorders.

Cécile Méjécase

Cécile Méjécase (Secretary) is a post-doctoral research fellow in Ocular Genomics and Therapeutics laboratory, directed by Pr Mariya Mooosajee at UCL Institute of Ophthalmology and at Francis Crick Institute, in London. She graduated BSc in 2013 and MSc specialty cellular biology and genetics in 2015 at Université de Versailles-Saint Quentin in France, with honor. Cécile analysed whole exome sequencing data to identify disease-causing defects in patients affected with inherited retinal dystrophy, under the supervision of Pr Isabelle Audo and Dr Christina Zeitz at Vision Institute in Paris, and she obtained her PhD in 2019 from Sorbonne-Université (France). After her PhD, she joined Pr Mariya Moosajee lab as post-doctoral research fellow and she studies autosomal dominant and autosomal recessive RDH12-related diseases. She models these diseases with retinal organoids, obtained from induced pluripotent stem cells derived from affected patient fibroblasts, to identify affected pathways for a better understanding of these RDH12-related retinal diseases.

Amanda Churchill

Amanda Churchill (Past Chair/Adviser) is a Consultant Paediatric Ophthalmologist with a special interest in Genetics and honorary Clinical Lecturer at the University of Bristol. During her training in Yorkshire, she undertook a PhD in the Department of Molecular Medicine at the University of Leeds studying the genetics of developmental eye disease including anterior segment dysgeneses and dominant optic atrophy. She spent a six month molecular genetics Fellowship with Professor Ed Stone in Iowa before moving to the University of Bristol in 2001. Her continued research on inherited eye disease led to the development of an NHS-funded genetic test for anterior segment dysgenesis. Moving away from simple Mendelian to complex genetics diseases, Amanda has devoted the last ten years to investigating the VEGF gene in angiogenic eye diseases. She has published a DNA profile associated with both age-related macular degeneration and proliferative diabetic retinopathy. Funding has included the The Wellcome Trust, Diabetes UK and the British Heart Foundation. Her current research is focussed on personalised medicine and using genetic profiling as a predictor of how an individual may respond to treatment. In addition to her research interests, she leads the Paediatric Ophthalmology unit at Bristol Eye Hospital and runs a monthly Genetic Eye Clinic. Amanda has previously been Treasurer of UKEGG for the last 4 years.

Carmel Toomes (Treasurer) is an Associate Professor in the School of Medicine at the University of Leeds in the field of molecular and cellular ophthalmology. She completed her PhD at the University of Manchester under the supervision of Professor Mike Dixon, studying the Molecular Genetics of Blepharophimosis, Ptosis and Epicathus Inversus Syndrome (BPES). Her first post-doctorial position was also in Manchester under the supervision of Professor Nalin Thakker, studying oral cancer and Papillon–Lefèvre syndrome. In 2000, she moved to Leeds to take up a post-doctoral position with Professor Chris Inglehearn investigating Optic Atrophy. In 2002 she became a principle investigator after obtaining funding from the Wellcome Trust, followed by a Royal Society University Research Fellowship, to investigate Familial Exudative Vitreoretinopathy (FEVR). At the end of her fellowship in 2013, Carmel took up her current post. She continues to work on FEVR along with other inherited retinal diseases including Foveal Hypoplasia, Leber Congenital Amaurosis, Optic Atrophy, Cone Rod Dystrophy and Retinitis Pigmentosa. She is a member of the European Retinal Disease Consortium (, the UK Inherited Retinal Disease Consortium (UK IRDC), the Hearing and Sight GeCIP and the Medical Advisory Board for RP Fighting Blindness.

Penny Clouston

Penny Clouston is a Consultant Clinical Scientist (Molecular Genetics) in the Oxford Regional Genetics Laboratories and a Fellow of the Royal College of Pathologists. After completing her PhD at the University of Leeds she joined the SE Thames Regional Genetics service as a Clinical Scientist in 1992 before moving to the Oxford Regional Genetics Laboratory in 1994. She is currently Lead for Molecular Genetics and Head of the Inherited Retinal Dystrophy, Hereditary Ataxias and Joubert syndrome services. Her aim is to deliver efficient, clinically effective genomic testing and to provide equitable access to diagnostic services for all patients with genetic conditions.
