About

Regan J. Hayward is a pioneering molecular biologist whose work is reshaping our understanding of bacterial gene expression at single-cell resolution. Their primary research focuses on developing and applying cutting-edge transcriptomic technologies to uncover the hidden heterogeneity within microbial populations. Hayward’s most significant contribution is the creation of MATQ-seq (Multiple Annealing and Tailing-based Quantitative single-cell RNA-seq), a groundbreaking method that enables, for the first time, the high-fidelity transcriptomic profiling of individual bacteria. This innovation, detailed in their highly influential 2025 paper, has already garnered 8 citations, signaling its rapid adoption as a foundational tool in the field. By overcoming the technical challenges of bacterial RNA analysis—such as low RNA content and lack of polyadenylation—Hayward’s work reveals how individual cells within a genetically identical population can exhibit vastly different behaviors, from antibiotic tolerance to metabolic specialization. This has profound implications for understanding biofilm formation, infection dynamics, and bacterial persistence. A rising star in their field, Hayward’s achievements promise to unlock new layers of complexity in microbial life, offering a powerful lens for future discoveries in microbiology and infectious disease research.
