Current Projects

Study of circumstellar disks of hot stars using a variety of ground based instruments including long-baseline optical interferometry and spectroscopy.  One application of this work is an improved understanding of the disk dynamics and disk-star interactions that are important physical phenomena in planet-forming circumstellar disks.
