Roles and responsibilities
Astronomer, Radio Astronomy: Focusing on star and planet formation research.
Principal Investigator: NRC New Beginnings; 350 Micron Commissioning Camera for the CCAT-p Telescope.
Co-Chair Science Working Group: Cradle of Life Science for the SKA Radio Telescope.
Science Team Member: NIRISS and NIRCam Instruments for James Webb Space Telescope.
Science Team Member: Future Space-Based Missions (CASTOR, SPICA, OST).
Current research and/or projects
JCMT Transient Survey (co-PI): A four-year monitoring of eight nearby star-forming regions with one-month cadence using the James Clerk Maxwell Telescope (JCMT) to detect brightness changes from young protostars. This is the first dedicated survey of protostellar variability in the sub-mm.
Planets in Formation (Lead): A Guaranteed Time JWST NIRISS AMI study of nearby very young stars surrounded by transition disks and possibly harbouring planets.
FAUST (Team Member): Fifty AU Study of the chemistry in the disk/envelope system of Solar-like protostars (ALMA Large Project).
Taurus Disks (Team Member): An Unbiased Survey of disk structures around young stars in Taurus (ALMA Project).
