Ethan Lopes
Ph.D. Student in Geophysics, admitted Autumn 2021
BioI study how secondary magnetic minerals form through fluid–rock interactions and how their magnetic signals can reveal broader geological processes. My research draws upon the interconnected nature of ocean and planetary sciences. By applying a planetary perspective to Earth systems, I aim to both test planetary hypotheses and reevaluate fundamental geologic processes. I investigate these fundamental processes through experimental work that integrates rock magnetism and rock physics—two deeply interconnected disciplines—alongside advanced imaging techniques.

Current Research and Scholarly InterestsResearch
I work to discover and understand the relationship between geophysical measurements and the rock and fluid properties that they sample in the Earth. My students and I have begun to understand the impact of rock type, porosity, pore fluids, temperature, and stress on seismic wave propagation and electromagnetic response. We are also working to quantify the links between geophysical measurements and the sedimentary and diagenetic processes that determine rock mineralogy and texture. Ultimately, this work allows us to better infer, from geophysical images, the composition and physical conditions at depth.
Teaching
I teach courses for graduate and undergraduate students on rock physics--the study of the physical properties of rocks and how they can be detected and mapped using seismic and electrical methods. This includes theory, laboratory measurements, and field data analysis. I also lead seminars in which students present and critique their ongoing research in rock physics.
