About Us

Austin Humphries

Dr. Austin Humphries is President of MMS. Dr. Humphries is a marine biologist specializing in the complex relationship between people and the sea. With a Ph.D. in Marine Biology from Rhodes University, his research integrates field data—from underwater fish surveys and fisheries catches to fisher interviews and household surveys—to analyze social-ecological interactions in coastal and marine systems. Using statistical tools and computer simulations, he explores the trade-offs between human needs and resource sustainability, informing policy solutions that support both marine ecosystems and fishing communities. Dr. Humphries’ work spans diverse fisheries, from bioeconomic modeling of mud crab fattening in Micronesia to studying the impacts of distant water fleets on food security in developing nations. He also investigates how small-scale lobster fishers in Vietnam are adapting to climate change while preserving their cultural heritage. His research is rooted in collaboration with fishers and policymakers, ensuring practical and sustainable fisheries management.
