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 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.
- Sep 2014: Paper submitted!, with Neal Turner (JPL) and Colin McNally (NBI), on the Rossby wave instability in the outer dead/active zone transition.
- Sep 2014: Talk at McGill. Be there!
- May 2014: Invited seminar at UCLA. Be there!
- May 2014: Paper submitted! First-authored by Alex Hubbard (AMNH), on the onset of decretion in disks by Maxwell stresses.
- May 2014: Paper accepted! Solo-author work on the newly-discovered linear convective overstability in accretion disks.
- Apr 2014: Invited seminar at Berkeley. Be there!
- Mar 2014: Paper submitted! First-authored by Alex Richert (Penn State), on an interesting behaviour we found in the wakes of high-mass planets in disks.
- Mar 2014: Paper submitted! First-authored by Natalie Raettig (MPIA-Heidelberg), on particle trapping and streaming instability in disk vortices.
- Mar 2014: Konnichiwa, Nihon! Visiting Nagoya University and Tokyo Tech for 3 weeks.
- Aug 2013: Paper accepted! First-author work, with Min-Kai Lin (CITA), deriving the analytical solution for dust trapping by disk vortices. The results are applicable to the large asymmetries recently seen in mm and sub-mm observations. (Update: this has been called the Lyra-Lin solution).
- Jul 2013: Paper accepted! First-author work, published in Nature, in collaboration with Marc Kuchner (GSFC), on the photoelectric instability in debris and transitional disks, and how it leads to the usual patterns attributed to unseen planets.
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.
