Anthony Edward Walsby, BSc(Birm), PhD(Lond), FRS, is the Emeritus Professor of Microbiology at the School of Biological Sciences, University of Bristol.Шаблон:Citation needed

He is a researcher in the fields of Algae, Cyanobacteria, lake ecology, gas vesicles/vacuoles and genetics, covering the European lakes and Baltic Sea. He is noted for his discovery of Haloquadratum walsbyi in brine ponds on the Sinai Peninsula in 1980. He was elected Fellow of the Royal Society, 11 March 1993.

Specifically his research includes:

• Gas vesicles of cyanobacteria: physiology; structure; molecular biology; ecology
• The natural selection of gas vesicles in relation to depth of lakes and oceans
• Population genetics of cyanobacteria using PCR on single filaments from lakes
• The cyanobacterium Planktothrix rubescens in stratified lakes
• Calculating the daily integrals of growth and photosynthesis in lakes
