Assistant Professor of Earth and Planetary Sciences
Department of Earth and Planetary Sciences
Faculty of Arts and Sciences
Roger Fu joined the Earth and Planetary Sciences Department as assistant professor in July 2017. His work focuses on using measurements of rock magnetism to understand planet formation in the early Solar System and conditions on the early Earth. To this end, Roger is building a new instrument called the Quantum Diamond Microscope (QDM), which is the first of its kind in an Earth sciences laboratory. The QDM, developed in conjunction with the Walsworth Lab in the Physics Department, offers much higher spatial resolutions than previous instruments, permitting isolation of particular magnetic signals in our rock samples. As an example, the Fu lab has been applying this technology to infer magnetic field strengths in the ancient Solar System’s protoplanetary disk by measuring meteorite samples. A parallel set of measurements is aimed to constrain the magnetic field environment on the young Earth more than 3.5 billion years ago by measuring single crystals of the mineral zircon.
Roger obtained his PhD from MIT in 2015. His thesis work led to a Nininger award from the Center for Meteorite Studies that same year. Before that, in 2009, he finished a joint concentration in Earth and Planetary Sciences and Astrophysics at Harvard. Thanks to a Frederick Sheldon Fellowship, Roger performed an ethnographic field study of the astronomical traditions of the Mapuche people between 2009 and 2010.
