The proposed research focuses on three central topics related to the inflationary universe. First, the PI will focus on the large scale structure of the eternally inflating universe and consider models where the dark energy is a stochastic parameter which varies from one place to another. The observational consequences of such models will be investigated and compared to data. Secondly the PI will continue a systematic investigation of the formation, evolution and observational signatures of various topological defects including those postulated in "braneworld" scenarios.Thirdly the PI will investigate the consequences of the new cosmological paradigm connected with eternal inflation and publish a popular book on the subject.

拟议的研究重点是与暴胀宇宙有关的三个中心主题。首先，PI将专注于永恒膨胀宇宙的大尺度结构，并考虑暗能量是一个随机参数的模型，从一个地方到另一个地方。 将对这些模型的观测结果进行调查，并与数据进行比较。 第二，PI将继续系统地研究各种拓扑缺陷的形成、演化和观测特征，包括“膜世界”情景中假设的拓扑缺陷。第三，PI将研究与永恒暴胀有关的新宇宙学范式的后果，并出版一本关于这一主题的畅销书。
