Overview


Using Cellular GWAS to Understand How Human Genetic Variation Impacts Host-pathogen Interactions and Disease
Despite improvements in public health, advancements in vaccines, and the development of many classes of antibiotics, infectious disease is still responsible for over a quarter of all deaths worldwide. However, even for the most devastating of pandemics, individuals demonstrate a large variability in the severity of infection. The long-term goal of the lab is to understand the genetic basis for differences in susceptibility to infection and related inflammatory disorders. We approach this question through a combination of experimental and computational approaches that combine high-throughput cell biology with quantitative human genetics. The identified genetic differences serve as the starting point for exploring new cell biology and human disease susceptibility genes.

Integrating single-cell sQTL mapping with deep-learning splicing prediction identifies causal variants under influenza infection.

Journal article Genome Biol · July 18, 2026 BACKGROUND: Realizing the full potential of human genetics requires identifying causal variants and genes underlying association signals. Molecular quantitative trait locus (molQTL) analyses, such as expression QTL (eQTL) and splicing QTL (sQTL), link gene ... Full text Link to item Cite

Disrupted Mitochondrial Copper Homeostasis Promotes Ferroptotic Stress, Senescence and MASLD Progression.

Preprint · June 17, 2026 BACKGROUND & AIMS: Systemic metabolic dysfunction promotes degenerative diseases in many organs, including liver and kidney. The liver is a master regulator of systemic metal ion homeostasis. Hepatic copper deficiency is increasingly observed in metabolic ... Full text Link to item Cite

Transcriptional mechanisms of sex-biased gene expression and their connections to disease-associated variation.

Journal article Hum Mol Genet · March 23, 2026 Humans display sexual dimorphism across many traits, but little is known about underlying genetic mechanisms and impacts on disease. We utilized single-cell RNA-seq of 480 lymphoblastoid cell lines (LCLs) to identify 1200 genes with significantly sex-biase ... Full text Link to item Cite
