Planet formation has been linked to the presence of substructures in protoplanetary disks around Class II sources in previous ALMA studies, such as DSHARP. It is unknown whether planet formation begins in these later stages, or in the earlier Class 0/I stage. The Early Planet Formation in Embedded Disks (eDisk) Survey aims to study 8 Class 0 and 11 Class I protostars at high angular resolution (~0.08") to understand when substructures start to develop in disks and how ubiquitous such substructures are in early embedded protostars. We present the first results to one object from this survey, IRAS 15398-3359, a very young Class 0 protostar in the Lupus I molecular cloud. Our analysis will aim to detect the very small protostellar disk inferred from previous ALMA observations and study its kinematic properties.
