My research focuses on studying fundamental physics of cosmology via measurements of structure on very large scales. I am the only non-US member of the small team which built the WMAP satellite, the first experiment to produce a map of the whole microwave sky with angular resolution below one degree. These measurements of the cosmic microwave background (CMB) have provided convincing evidence of the constituents of the universe including a constraint that w, the ratio of pressure to energy density during inflation, is near to -1, and, in our most recent data, a detection of a cosmic neutrino background.

我的研究重点是通过测量非常大尺度上的结构来研究宇宙学的基础物理。 我是建造WMAP卫星的小团队中唯一的非美国成员，这是第一个以低于一度的角分辨率绘制整个微波天空地图的实验。 这些宇宙微波背景（CMB）的测量提供了令人信服的证据，包括宇宙的组成，包括一个约束，即w，在膨胀过程中的压力与能量密度之比，接近-1，并且在我们最近的数据中，宇宙中微子背景的检测。
