SUMMARY:Planet Formation in the Era of ALMA\, Astronomy Colloquium\, K
 e Zhang\, University of Michigan
DESCRIPTION:Planetary systems are common in the universe\, and our sol
 ar system is just one outcome of a vast number of possibilities. This 
 great diversity is largely rooted and developed in their birth environ
 ments--- gas-rich protoplanetary disks around several Myr-old young st
 ars. Therefore\, studying the structures and evolutions of solids and 
 gaseous components in these disks are necessary for our understanding 
 of the diversity and ultimately the chance of habitability of planetar
 y systems. I will discuss recent results from The Atacama Large Millim
 eter/submillimeter Array (ALMA) in characterizing protoplanetary disks
 \,  and new insight/puzzles that these results add to our understandin
 g of planet formatting processes. In particular\, I will focus on thre
 e areas: (1) the commonality of substructures in disks and their links
  to planet(esimal) formation\, (2) new approaches to probe the planet-
 forming mid-plane region and locations of critical chemical transition
 s such as snowlines\, (3) direct determination of carbon and oxygen el
 emental abundances in disk atmospheres and their implication for the i
 nitial atmospheric composition of extra-solar gas giants.<br>
