Deep Phenotyping Core


The Deep Phenotyping Core is led Dr Jean-Charles Grivel. Dr. Grivel obtained his Ph.D. in immunology from the University of Aix Marseille II. He was a postdoctoral fellow at the National Cancer Institute (NIH, USA) and became a Staff Scientist in 2000 at the National Institute of Child Health and Human Development. He pioneered the development of human organ culture for studying the pathogenesis of HIV, Human Herpes Viruses and Measles virus as well as their interactions, which led to the granting of two patents. Dr Grivel has developed several high dimension immunoassays for the quantification of viral antigens and other immune system related proteins. He has also developed several flow cytometric methods for characterizing antigen-specific cellular responses as well as submicron particles. These methods are used for studying the role of microvesicles in heath and disease, especially in cardiovascular disease and cancer as well as to characterize the antigenic composition and maturation of viral particles. Dr Grivel has received the NIH Award of Merit in 2006. He currently directs the Deep Phenotyping Core of Sidra Medicine.

Sidra Medicine is aiming at delivering personalized medicine to the patients of Qatar and beyond. The systematic measurement and analysis of qualitative and quantitative traits of patients, known as Phenomics, completes the personalized medicine approach initiated by genomic approaches.  The Deep Phenotypic Core (DPC) provides a multifaceted phenomics platform dedicated to establishing cellular, molecular and functional phenotypes that complement genomics, transcriptomics, and clinical phenotypic analyses of patients. Relying on metabolomics, lipidomics, elemental chemical analysis, high-dimension proteomics, super-resolution microscopy and high-dimension flow cytometry, the DPC generates systematic, high-quality, validated precise molecular and cellular phenotypes of patients and enable true phenomic science in Qatar. The DPC aims at providing in depth and breadth the panels of diagnostic and investigational assays proposed in Sidra and in Qatar. The DPC mission is to provide the technical and intellectual frameworks for the realization of the second pillar of Sidra Medicine’s Research Personalized Medicine agenda: “Establishing an Advanced Diagnostics program”.

The Integrated Genomics Services department delivers genomics, molecular biology, informatics and animal model services to Sidra Medicine Principle Investigators, clinical scientists, Qatar Genome Programme PIs and external collaborators. The facilities aim to provide high-quality advanced services and data. IGS offers a portfolio that covers the extraction of genetic material from subject samples, their analysis using genomics and ‘omics techniques, the analysis of the resulting data and generation of interpretable results and the downstream generation and analysis of model animals to study effects and impacts of genetic variants. The department is structured into subgroups with specialized functions under one umbrella.
