We translate data into biological knowledge to develop better drugs and improve peoples' lives. To understand novel drug targets and drugging modalities, we exploit technologies in molecular biology that result in genome-scale data measurements. We evaluate, develop, and apply computational, statistical and machine learning methods to analyze these large, high-throughput, high-dimensional, multi-omic data. These data include human genetics (GWAS, CRISPR screens), genome-wide chromatin profiles (ATAC-seq, CUT&RUN, Hi-C), and RNA transcript measurements at both bulk and single-cell resolution (RNA-seq, spatial transcriptomics, long-read sequencing). To make data and code useful to other drug-hunters, we document our analyses in reproducible workflows and interactive graphic interfaces, we implement algorithms in well-documented software packages, and we follow the FAIR (Findability, Accessibility, Interoperability, and Reusability) Data Principles.

We lead the technological, data and design aspects of early drug-discovery projects conducted in close collaboration with multidisciplinary teams at NIBR. Our projects span several disease areas, including liver, blood, musculoskeletal and neurodegenerative conditions. Our research is done following Novartis’ inspired, curious, and unbossed values, which enable self-empowerment and a speak-up culture.
