Environmental Interactions of Protoplanetary Disks: Early-Stage Planetesimal Formation and Late Infall

Talk about all of my Ph.D. projects regarding early-stage and late infall, and how it influences protoplanetary disks and planet formation. The talk was given at two seminars in Tokyo, Japan. First, it was given at the planet seminar at the National Astronomical Observatory of Japan.
