MIT Department Of Earth, Atmospheric And Planetary Sciences

At MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS), we are driven by curiosity. How did life originate? Is it unique to Earth? When did the oceans and atmosphere form? What can 4.3 billion year-old rocks tell us about our past and future climate and its influence on life? We delve into questions about the fundamental forces shaping the natural world, spanning the full scale of space and time—from microscale structures of minerals and aerosols to the composition of massive planetary bodies light years away; from earthquakes which strike in a split second to the co-evolution of life and environmental systems over billions of years. Our work stands at the crossroads between basic theory—be it physics, biology, or chemistry—and practical applications to sustain life on Earth, allowing us to both benefit from and protect our planet. The breadth of our research is unparalleled. In our pursuit of answers, EAPS students and faculty cross boundaries between disciplines, fostering interdepartmental collaborations unmatched by any other program. Geologists team with atmospheric scientists to understand how a model of changing precipitation trends can help predict landslides. DNA sequencing of extant organisms combined with isotopic dating of ancient rocks reveals the origins of animal life in sea sponges and the influence of tiny microbes on mass extinction. Ours is a truly interdisciplinary effort to understand nature in all of its forms.
