Scott Gallager has been interested in the inhabitants of lakes and oceans since his college days. His interest in engineering and electronics goes back even further: While still in high school, he published his first paper, “A Color TV You Can Build,” in Popular Mechanics. He earned a bachelor’s degree in biology and environmental sciences at Alfred University and a master’s degree in marine sciences at Long Island University, and then worked at WHOI as a research assistant, associate, and specialist while completing a Ph.D. in biology at Boston University. After a postdoctoral position at Dalhousie University, he returned to WHOI, where he is an associate scientist in the Biology Department. His interests have led him to use electronic and computer technology to study how planktonic organisms live in and adapt to their environments, and their functional morphology and biophysics. He works in the coastal Atlantic, Arctic, and Southern Oceans, building instruments to remotely monitor ocean ecosystems. He often talks to teachers and students and has originated a Boy Scout merit badge program in oceanography.
