[Peer-Reviewed Papers] [Full ADS Bibliography] [Teaching] [CV] [Research Statement]


My main areas of research are star formation, young stellar objects, and the assembly of star clusters and associations. My work is based on observations of nearby star-forming regions using many parts of the electromagnetic spectrum, from X-ray to optical to millimeter wavelenghts.

I am also interested in astrostatistics, in particular, mixture models and spatial point processes.
