Earth Scientist Gage Coon Explores Microbes for Climate Solutions

Gage Coon, a PhD student at MIT, researches how microorganisms cycle carbon and sulfur, aiming to leverage these processes for climate change mitigation. His hands-on upbringing influenced his scientific approach, focusing on tangible, experimental work.

Coon's childhood in rural Tennessee, filled with outdoor exploration and practical learning, instilled an appreciation for the natural world that shapes his current research. He studies microbes, organisms too small to see, and their role in environmental processes.

Initially drawn to chemistry, Coon discovered microbial biogeochemistry at the University of Tennessee, finding a field that combined his interests in chemistry, the environment, and climate processes. As a first-generation college student, he learned about PhD programs later in his academic journey but was captivated by the prospect of a career dedicated to continuous learning.

His undergraduate research involved studying microbes in marine sediments and participating in research cruises. One such cruise to the Atlantic continental slope focused on methane seeps and microbial roles in preventing methane release into the atmosphere, an experience that deepened his understanding of the organisms he studied.

At MIT, under advisor Tanja Bosak, Coon is focusing on the applications of microbial carbon and sulfur cycling. A major project involves using microbes to reduce methane emissions from wastewater treatment. By adding gypsum, a waste product, to anaerobic digesters, the process converts methane into carbonate and produces elemental sulfur, turning waste into valuable materials and reducing greenhouse gas emissions.

This wastewater treatment innovation aims to be both environmentally beneficial and economically viable. Following successful lab experiments, researchers are planning pilot-scale testing and engaging with companies interested in adapting the technology for larger facilities. The goal is to contribute significantly to global emission reduction efforts.

Coon's PhD research also includes investigating geological processes that produce molecular hydrogen, a potential carbon-free energy source, and studying microbial competition for acetate in coastal wetlands to improve climate predictions and mitigation strategies.

Beyond his research, Coon enjoys mentoring younger students and maintains his connection to nature through hiking and playing bluegrass guitar. He plans to continue in academia, government, or by helping implement environmental technologies, driven by a desire to produce knowledge that improves the world.
