Bernadette Johnson serves as a Biodiversity Informatics and Data Science Postdoctoral Fellow within the Department of Zoology at the University of British Columbia's Faculty of Science. She is actively affiliated with the Mank Lab, where her research program centers on the evolutionary genomics of sexual selection and sexual conflict, primarily utilizing livebearing Poecilia fishes as model systems. Her dual fellowship roles underscore her interdisciplinary focus bridging biodiversity science and computational data analysis.
Johnson's research interests converge at the intersection of evolutionary biology and genomics, with specific emphasis on how sexual selection pressures shape genome architecture and transcriptome dynamics. She employs cutting-edge bioinformatics approaches to investigate sex chromosome evolution, dosage compensation mechanisms, and the genomic signatures of reproductive strategies across fish lineages. Her work frequently incorporates marine biodiversity datasets, particularly from syngnathiform fishes (pipefishes and seahorses), to explore fundamental questions about sexual dimorphism and parental investment.
Analysis of her publication record from 2017-2025 reveals consistent methodological innovation in fish genomics, with recurring investigations into sex chromosome conservation, brood pouch transcriptomics, and environmental endocrine disruption. Her studies demonstrate particular expertise in comparative genome assembly, transcriptomic sensitivity to experimental variables, and the evolutionary implications of sex-role reversal systems. This body of work establishes her as a contributor to both theoretical evolutionary biology and practical biodiversity informatics frameworks.
As a member of UBC's Biodiversity Research Centre ecosystem, Johnson collaborates within a vibrant interdisciplinary network focused on organismal diversity. Her affiliation with the Mank Lab provides access to specialized genomic resources and evolutionary model systems, facilitating her investigations into the molecular basis of reproductive evolution. Her research trajectory suggests continued contributions to understanding how genomic architectures evolve under sexual selection pressures in aquatic environments.
