Person overviewChris Wallace is a Wellcome Trust Senior Research Fellow at the University of Cambridge and joined the MRC BSU as an honorary Programme Leader in February 2016. Prior to this, she held fellowships from the Wellcome Trust and the British Heart Foundation at other institutes in Cambridge and Queen Mary University of London, where she worked on various aspects of statistical genomics. Her focus is on the twin goals of using genomic analysis to make meaningful contributions to the understanding of human autoimmune disease and the development of statistical methodology to enable these contributions.
BSU Research overviewIn the last ten years, genomewide association studies have identified hundreds of associations between genetic variation and autoimmune disease, but translation to biologicial understanding and clinical impact has been slow.Chris Wallace's new research programme has two complementary aims. First, to develop the statistical tools needed to robustly and empirically link each genetic association with a gene, cell type, stimulatory condition and ultimately a biological pathway. Specifically, this requires methods for:
- horizontal integration of different layers of omics data
- adjustment for correlation and structure in omics data when testing association, without compromising computational efficiency
- "fine mapping" causal genetic variants from amongst associated variants in genetic association data
