About me
Greetings, and welcome to my homepage. I am an Associate Professor of Astronomy at New Mexico State University.
My research focuses on fundamental processes of planet formation theory, such as the nature of turbulence in circumstellar disks, streaming instability, and pebble accretion, enabling direct comparisons with observational evidence from exoplanets and the Solar system.
I am one of the principal investigators in the PFITS+ collaboration, involving six institutions and nearly 20 members.
Research Interests
Planet formation, exoplanets, accretion disks, planet migration; fluid mechanics, magnetohydrodynamics, dust dynamics, radiative transfer. Icy shell convection, active galactic nuclei. Code development, supercomputing. You can read more about my research here

My group`s research is currently funded by NSF via grant AST-2511672; by the New Mexico Space Grant consortium via grant 80NSSC25M7069; by the NASA Emerging Worlds Program via grants 80NSSC24K1447, 80NSSC25K7414; and the NASA Exoplanet Research Program via grant 80NSSC24K0959. My supercomputer needs are supported by the NMSU Discovery cluster, NASA Pleiades supercluster, and XSEDE/TACC Stampede3 through allocation TG-AST140014.
Former groups
I received my Ph.D. in February 2009 from Uppsala University, Sweden. Before joining the faculty at NMSU, I did postdocs at NASA-JPL/Caltech, as a Sagan fellow (class of 2011, currently the NASA Hubble Fellowship Program - NHFP), and at the American Museum of Natural History, in New York City. I was also a research assistant at the Max Planck Institute for Astronomy (MPIA), in Heidelberg, Germany.
