Bob Howarth doesn’t go looking for fights, but he doesn’t hide from them, either. Howarth, the David R. Atkinson Professor of Ecology and Environmental Biology in the College of Agriculture and Life Sciences, has been a leader in the field of biogeochemistry for almost 40 years. His pioneering research has focused on ocean dead zones caused by nutrient pollution, methane’s role in climate change, the environmental impact of hydraulic fracturing for natural gas and the high carbon footprint of “blue” hydrogen. These groundbreaking studies have influenced policy and often sparked controversy; most recently, a lobbyist for a U.K. hydrogen group resigned just days after Howarth’s blue hydrogen study was published.
“When I decided I wanted to be a scientist, I could see biogeochemistry as a way to do science that was fun but was also something that mattered and had immediate, public impact,” Howarth said. “I’ve never set out deliberately looking for confrontation, but I have deliberately taken on questions that are challenging and where the answers matter.”
