Post-doctoral fellow (2011-2014)


Main Research Fields

My main research topic is star and planet formation, specifically the structure and evolution of circumstellar disks around young stars. I focus much of my work on young eruptive stars (FUors and EXors). These are pre-main sequence objects with temporarily increased accretion rate resulting in powerful brightenings in the whole optical-infrared regime. My goal is to understand the physics behind the accretion process and the effect of the increased heating on the disk. I am also interested in variability of young stellar objects in general at various wavelengths from the optical to the millimeter, and what it can tell us about disk structure. Part of my work focuses on debris disks, and the relationship of debris dust and planet formation. I am experienced in several observational techniques from imaging and spectroscopy through polarimetry to interferometry.


  • primordial and debris disks
  • accretion process during star formation
  • eruptive phenomenon during pre-main sequence
  • optical, infrared, and millimeter observations
