Greetings, and welcome to my homepage. I have just completed a Sagan postdoctoral fellow at NASA's Jet Propulsion Laboratory and Caltech's Division of Geological and Planetary Sciences, and am currently between contracts.
My current research focuses around computer simulations of circumstellar disks, with emphasis on the processes that lead to planet formation, such as magnetorotational turbulence, streaming instability, and disk vortices. A goal of this research is to establish a model that combines all the necessary physics to simulate the formation of planetary systems, and enable self-consistent comparisons with the astronomical observations.
I am also interested in icy moons and habitability. In addition, I have previously worked on star formation and stellar activity, both observationally. You can read more about my research here.
Research InterestsAccretion disks, exoplanets, planet formation, planet migration; fluid mechanics, magnetohydrodynamics, dust dynamics; star formation, young stellar objects, stellar atmospheres; code development, supercomputing. Icy moons, habitability.

I received my Ph.D. in February 2009 from Uppsala University, Sweden. Before moving to sunny Pasadena, I was a postdoc at the American Museum of Natural History, in New York City; and before that, a research assistant at the Max Planck Institute for Astronomy (MPIA), in Heidelberg, Germany. Before my Ph.D. I worked as an observer. I was a research assistant at CTIO (La Serena, Chile) and ESO (Garching, Germany), as well as a summer intern at Space Telescope, in Baltimore. My undergrad is on Astronomy, from the Federal University of Rio de Janeiro.
