Our goals are to understand the biology of genomes and to advance genomic medicine<\/strong><\/a>.<\/p>\n

We are interested in elucidating the genetic basis of human traits and diseases using novel statistical &<\/strong> computational <\/strong>methodologies<\/strong><\/a>, integrative analyses of heterogeneous multi-omics data<\/a><\/strong>, and innovative experimental approaches<\/strong><\/a>. A primary research focus is the development of methods in statistical and population genetics<\/strong><\/a>. We pursue deep learning<\/strong><\/a> methods in genomics. The knowledge gained can be the basis for a genetics-driven forward pharmacology that enables identification of molecules with a desired phenotypic effect or mechanism of action. We leverage functional genomics<\/strong><\/a> to dissect the transcriptional regulatory logic and its context specificity in order to advance our understanding of biological mechanisms. Using genomic and multiomic approaches, we investigate the\u00a0regulation of metabolism<\/strong><\/a>\u00a0in human cells.\u00a0We aim to advance a new genomics of interorgan communication<\/a><\/strong> via extracellular vesicles.<\/p>\n

Here is a list of select publications<\/strong><\/a> and the latest news<\/strong><\/a>. See also this talk series<\/a>, which reflects some of our research interests.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

We are developing approaches and methodologies that are broadly applicable, but we may evaluate these with specific disease<\/a> areas, cell types, or genes (or related genomes<\/a>). Our goals are to understand the biology of genomes and to advance genomic medicine. Some active areas of research are described below, but see our publications<\/a><\/strong> for a more complete picture of our research activities.<\/p>\n

\"ART_alzheimers\"FUNCTIONAL GENOMICS & PRINCIPLES OF COMPLEX TRAIT GENETICS<\/span><\/span><\/strong><\/p>\n

We develop multi-disciplinary approaches to mapping the role of genetic variation in the development and function of the nervous system and elucidating the precise molecular and cellular mechanisms underlying brain disease phenotypes. Ongoing research includes modeling the transcriptional regulatory programs in the brain, in collaboration with human geneticists, neuroscientists, and evolutionary biologists. This work has obvious relevance to understanding the molecular basis of neuropsychiatric and neurodegenerative disorders<\/a><\/strong>.<\/p>\n

\"\"<\/a>HUMAN METABOLISM<\/span><\/span><\/strong><\/p>\n

An important challenge in mechanistic understanding of human health and disease is the biochemical characterization of metabolism. Identifying the substrates of metabolic gene products is critical to elucidating their function in physiology and disease. We have been developing approaches<\/a><\/strong> to deorphanizing metabolic enzymes and transporters and exploring connections<\/a><\/strong> to human disease.<\/p>\n

\"CRISPR_MO.jpg\"BRIDGING GENOMICS and PHENOMICS<\/span><\/strong><\/span><\/p>\n

Recent advances have enabled precise genome editing with high efficiency and minimal off-target effects. Meanwhile, EHR-linked DNA biobanks have been unprecedented in their efficiency for human genetic discovery. We are conducting studies and developing methods across systems. In recent collaboration with colleagues at Vanderbilt, we integrated human phenomic data and in vivo<\/em> loss-of-function models generated using CRISPR-Cas9<\/a><\/strong> genome editing strategies and morpholino (MO) oligonucleotide-based protein knockdown to characterize a mechanism that implicates vascular biology in the eye disease phenome.<\/p>\n

 <\/p>\n

\"\"<\/a>iPSCs, FUNCTIONAL GENOMICS, and DISEASE<\/span><\/strong><\/span><\/p>\n

Current research interests in complex traits genetics include functionally characterizing the genetic architecture of complex diseases, using induced pluripotent stem cells as a platform. We leverage this platform for disease modeling (after differentiation into relevant cell types), allowing us to study disease mechanisms and validate potential targets. The platform enables functional investigations of disease in patient-specific cells, potentially advancing precision genomic medicine.\u00a0<\/span><\/p>\n

\"Single_cell.P\"SINGLE-CELL OMICS and MULTI-OMICS<\/span><\/strong><\/span><\/p>\n

I work (with Dr. Ravi Shah) on single-cell omics, proteomics, genomics, and phenomics in cardiovascular and cardiometabolic disease studies.<\/p>\n

We have developed a deep learning methodology<\/strong><\/a> leveraging single-nucleus RNA sequencing.<\/p>\n

Dr. Eric Strobl and I have worked on developing the <\/span>omnigenic root causal model<\/span><\/a><\/strong> (by integrating Perturb-seq) and the <\/span>transcriptome-wide root causal inference<\/span><\/a><\/strong> (TWRCI) methodology.<\/span><\/p>\n

 <\/p>\n

EXTRACELLULAR VESICLES<\/span><\/strong><\/span><\/p>\n

I (with Drs. Saumya Das<\/a> and Ravi Shah<\/a>) develop concepts and tools for a new genomics of interorgan communication<\/strong><\/a>. Extracellular vesicles (EVs) are nano-sized structures released by cells that carry a wide range of cargo (proteins, lipids, nucleic acids, etc.) to other cells, facilitating interorgan communication and affecting biological processes. We investigate the role of EVs in human health and disease through genomic techniques.<\/p>\n

STRUCTURE, DYNAMICS, and GENOMICS<\/span><\/strong><\/span><\/p>\n

In recent highly interdisciplinary work, Dr Gamazon is developing computational approaches to studying the structure, dynamics, and stability of biological molecules within Density Functional Theory (DFT), molecular dynamics, and coarse-grained modelling and using experimental techniques (e.g., X-ray crystallography, NMR spectroscopy, and cryo-electron microscopy).<\/p>\n

He is co-founder of the Chemistry and Disease Genomics Group (CDGG) with David Collison<\/a> (Manchester) and Lalarukh Akhter (Cambridge).<\/p>\n

 <\/p>\n

Dr. Gamazon is part of the DEFINE-T2D Consortium<\/a><\/strong>, the GTEx Consortium<\/strong><\/a>, and the T2D-GENES Consortium<\/a><\/strong>.\u00a0 He was also a member of the International Warfarin Pharmacogenetics Consortium<\/a> GWAS team. As part of the Pharmacogenomics<\/strong><\/a> of Anticancer Agents Research (PAAR) Group at the University of Chicago, he developed and applied computational approaches to the study of the genetic basis of cancer susceptibility and of response to a wide array of molecularly diverse chemotherapeutics.<\/p>\n
