In the last two decades thousands of exoplanets have been discovered, showing that planets are ubiquitous throughout the Milky Way. However, the formation of planets itself remains a mystery. Protoplanetary disks of gas and dust around young stars are the birth cradles of planets, and analyzing their properties and structures give further insight in the planet formation process. ALMA has revolutionized our view of protoplanetary disks: rather than smooth profiles, it has turned out that disks contain gaps, rings, asymmetries and spiral arms in dust and gas, all indicators of active disk dynamics and recently formed planets. The observations are of such exquisite detail that they can be compared directly with predictions of hydrodynamical models of disk evolution and planet-disk interaction. However, millimeter emission is still optically thick and dust structure cannot be fully recovered, in particular in the inner part of the disks where likely most of the planet formation happens. The Next Generation Very Large Array will allow to us to observe protoplanetary disks at even better resolution than ALMA in optically thin centimeter wavelengths on scales of our Solar System. In particular, ngVLA will reveal the distribution of the centimeter-sized dust grains, the building blocks of Earth like planets, and resolve free-free emission in disk winds. I will discuss the future possibilities of ngVLA on planet formation studies. ************************************************************** Dr. Nienke van der Marel NRC Research Fellow NRC Herzberg 5071 West Saanich Rd Victoria BC V9E 2E7 Canada Room 324 Phone: (+1)250-363-3247 E-mail: astro@nienkevandermarel.com Alternative e-mail: nienkevandermarel@gmail.com Web: http://www.nienkevandermarel.com/ **************************************************************
