The study of star formation is quickly maturing. Stars form within regions of dense molecular gas and are enshrouded at the earliest stages within this prenatal material, allowing observations only at infrared to radio wavelengths. My research investigates three aspects of star formation: (1) the formation of structure within molecular clouds, (2) the collapse of prestellar cores to protostars and circumstellar disks (and subsequently to planets), and (3) the formation and evolution of the molecular clouds themselves.

恒星形成的研究正在迅速成熟。恒星形成于致密的分子气体区域，并在这种产前物质的最早阶段被覆盖，只能在红外到射电波长进行观测。我的研究考察了恒星形成的三个方面：(1)分子云内部结构的形成，(2)恒星前核心塌陷到原恒星和星盘(随后到行星)，以及(3)分子云本身的形成和演化。
