My research is to understand the interaction between gravity and quantum mechanics. As such it encompasses a wide range of topics-- one must understand quantum theory, in particular both what has been called the measurement problem and the process of decoherence. One must also understand gravitational theory, in particular Einstein's theory of General relativity. My own focus is on black holes and on the early universe. After our successful measurement of the radiation predicted by Hawking (for black holes) and me (for other horizons like fluid systems) in a water flume, this project will continue the search for and analysys of a wide variety of analog systems in which the process could occur and be measured (especially the direct observation of the spontaneous emission). This research requires the understanding of a wide variety of systems. After developing and exact theory of surface waves in flowing fluids over an uneven bottom, I need to generalise this to rotational, viscous fluids. Understanding the non-linearities in optical transmission in wave guides is important for optical anlogs to black holes. Teh quantum behaviour of BECs near horizons needs to be understood to aid the experimentalists using these systems to search for the radiation. Quantum mechanics needs to be better understood, especially the role of quantum coherence. Continuing my research on false decoherence, the characterization of the role of decoherence in quantum systems, including on the measurement problem, needs to be better understood. This has applications also to black holes (the Information puzzle) and on the early universe cosmology. In this aspect, Penrose's intuitions about gravity induced decoherence will also be studied. Finally, R Schuetzhold and I are writing a book on Dumb Holes (analogs to black holes) to further encourage both theoretical and experimental study in this field.

我的研究是了解引力和量子力学之间的相互作用。因此，它包含了广泛的主题-一个人必须了解量子理论，特别是所谓的测量问题和退相干过程。人们还必须了解引力理论，特别是爱因斯坦的广义相对论。我自己的重点是黑洞和早期宇宙。 在我们成功地测量了霍金（黑洞）和我（其他视界，如流体系统）在水槽中预测的辐射之后，这个项目将继续寻找和分析各种各样的模拟系统，在这些系统中，这个过程可能发生并被测量（特别是自发辐射的直接观察）。 这项研究需要了解各种各样的系统。在开发和精确的理论表面波在流动的流体在一个不平坦的底部，我需要概括这一旋转，粘性流体。理解光在波导中传输的非线性对于黑洞的光学模拟是很重要的。需要了解BEC在视界附近的量子行为，以帮助实验学家使用这些系统来寻找辐射。 需要更好地理解量子力学，特别是量子相干性的作用。继续我对虚假退相干的研究，需要更好地理解量子系统中退相干作用的表征，包括测量问题。这也适用于黑洞（信息之谜）和早期宇宙宇宙学。 在这方面，彭罗斯关于引力诱导退相干的直觉也将被研究。 最后，R Schuetzhold和我正在写一本关于哑洞（类似于黑洞）的书，以进一步鼓励这一领域的理论和实验研究。
