I am currently a Postdoc Scholar at the Woods Hole Oceanographic Institution, collaborating with Dr. Sune Nielsen and Dr. Frieder Klein in projects that explore the deep cycling of incompatible elements in subduction zones, and the use of secondary silicate products in altered oceanic crust as archives of past seawater chemistry. In October/2019, I graduated from a Ph.D. in the broad field of low-temperature stable isotope geochemistry under the mentorship of Dr. John Higgins at Princeton University. At WHOI, I work on projects that aim to bridge the low- and high-temperature geochemistry fields, and apply stable isotopes as chemical tracers of mass transfer mechanisms between Earth's surface and its interior.
Along with Dr. Higgins and collaborators, I developed a method for the high-precision measurement of K isotopes (41K/39K) using a state-of-the-art multicollector inductively coupled plasma mass spectrometer (MC-ICP-MS). With our improved measurement precision (ca. 0.17‰), I have been able to explore K isotope variability in both geological and biological systems. My research contributions have focused on the application of this novel isotope system to studies of secondary silicate formation and low-temperature oceanic crust alteration, and how these processes relate to the long-term carbon cycle and climate stability on Earth.
Short personal bio
I am originally from Recife, a charming coastal city in Pernambuco, Brazil. Homesickness apart, it was thanks to my American, liberal arts education that I was introduced to the wonders of the earth sciences. Shout outs to my alma mater Amherst College and to the wonderful Mr. Koenig, whose charitable work has allowed a number of African and South American students, like myself, to experience one of the best liberal arts curricula out there.
Apart from doing science, I also dig reading memoirs and thrillers, listening to crime podcasts and uplifting TED talks (it's all about balance, folks), and dancing like nobody is watching. If I could sing, science would never had heard of me.
