Greetings, and welcome to my homepage. I am currently a Sagan postdoctoral fellow at NASA's Jet Propulsion Laboratory and Caltech's Division of Geological and Planetary Sciences.

My current research interests revolve around the theory of planet formation, a very ancient question. "How did the Earth come to be?". Virtually every society in recorded history tried at some point to answer this question. In modern times the quest has been stirred up by the discovery of the roughly 1000 exoplanets known to date; the vast majority of these lying in planetary systems remarkably different from our own. A major goal of my research is to understand this diversity, at the same time tracing back our own origin.

I do it by reconstructing in simulation models the conditions that existed in the Solar Nebula and related protoplanetary disks. In addition to hydrodynamics, I include physical processes such as magnetic fields and turbulence, thermodynamics and radiation, dust and aerodynamics. By doing this, I construct, harnessing the full power of modern computers, a laboratory to consistently study the processes taking place during planet formation.

I have been since 2005 a co-developer of the Pencil Code, an open source, collaborative, high order finite difference magneto-hydrodynamics code that is highly modular and versatile. I employ the code in high-end computing, having used as many as 73,728 processors for scaling tests, and 18,432 for published production runs, both in the NICS-Kraken supercluster (for comparison, the celebrated Millennium run was calculated on 512 processors). Videos of the simulations are publicly available in my YouTube channels: channel 1 and channel 2.

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.
