Description of Research Expertise

The overarching goal of the Vahedi laboratory is to understand the molecular mechanisms through which genomic information in our immune cells is interpreted in normal development and further dissect how common genetic variation can lead to misinterpretation of the genetic material in immune mediated diseases. The multidisciplinary nature of our laboratory allows us to exploit cutting-edge computational and experimental approaches and generate unbiased maps of genome organization in primary immune cells in humans and mice. We further follow our hypothesis-generating yet unbiased efforts with experiments dissecting the mechanisms of our predictions using genome editing in mice or cell lines which provides us with an unparalleled opportunity to rigorously define the link between genetics and chromatin organization.
