Oz in the Lab
Oz's fascination with biology has taken him across many different disciplines during his research career.
Oz is doing his PhD at the UCL Centre for Advanced Biomedical Imaging. He is studying the newly discovered glymphatic pathway in the brain, which is one of many clearance systems that helps the brain get rid of waste products.
Oz is specifically studying this system's role in Alzheimer's disease, which has two hallmark waste proteins - amyloid beta and tau. Using magnetic resonance imaging and histological methods, Oz aims to identify the link between the accumulation of these proteins and their clearance from the brain to understand if glymphatic impairment has a role in Alzheimer's disease. Oz has also worked on developing imaging biomarkers for Alzheimer's disease in collaboration with Eli Lilly & Company.
Prior to this, Oz worked at the Wellcome Trust Sanger Institute in Cambridge within the Mouse Genetics Programme - a large scale phenotyping project that aimed to characterise and phenotype the entire mouse genome in order to understand the genetic basis of human development and disease. Oz's role in this project was to develop and refine X-ray imaging and body composition analysis techniques for metabolic phenotyping.
Oz studied physiology at the University of Hertfordshire. In his final year research project, he investigated the use of statins for improving cardiovascular tone. During this degree, he also did a research placement at Brunel University in West London, where he studied DNA methylation patterns and mismatch repair mechanisms in genes that cause Friedreich ataxia.
It was in these labs that Oz got his first taste in scientific research and decided that he wanted to become a full time scientist.
