Abstract :
The Atacama Large Millimeter Array (ALMA) interferometer project will being science operations in 2011. With its high angular resolution and sensitive continuum and spectroscopic capabilities from 84-850 GHz, it will dramatically advance our observational understanding of the planet formation process by providing unprecedented measurements of the physical conditions in the birth sites of planets, the gas and dust disks around young stars. I will present an overview of a few key ALMA experiments that can be used to address some fundamental issues related to the structure and evolution of these protoplanetary disks, as well as a new technique that may provide unique, new access to characterize extremely young systems of exoplanets.
