Katie Marshall

Katie Marshall is an Assistant Professor in the Department of Zoology at the University of British Columbia’s Faculty of Science. Her research focuses on the physiological and ecological mechanisms underlying species’ survival in cold environments, particularly in intertidal invertebrates and forest pest insects. She explores how low-temperature adaptation affects population growth and geographic range limits, aiming to predict climate change impacts on species distributions. Dr. Marshall is affiliated with the Biodiversity Research Centre and the Comparative Physiology Group, emphasizing interdisciplinary collaboration in ecology and evolutionary biology.

Her work integrates biological and environmental disciplines, combining molecular studies with ecological observations. For instance, she investigates ice-binding proteins in marine invertebrates and metabolic adaptations in insects and mussels exposed to freezing conditions. She also utilizes advanced technologies like machine learning and DNA metabarcoding for species classification and ecosystem monitoring.

Dr. Marshall’s research addresses key questions about why species have specific geographic ranges and how they might respond to environmental changes. Recent studies highlight themes such as the evolutionary origins of cold tolerance, the effects of temperature fluctuations on insect survival, and the interplay between climate variables and organismal physiology. She emphasizes understanding functional traits and eco-evolutionary dynamics to improve predictive models for species range shifts and ecosystem management.

Though no specific scientific awards or grants are listed in the provided texts, her contributions to biodiversity and physiological ecology are evident through her active research and lab leadership. The Marshall Lab collaborates broadly within the Zoology Department and across UBC’s Biodiversity Research Centre to advance knowledge in these critical areas.
