Among the four fundamental forces in nature, only gravity has not been quantized, nor has it been unified with the other three (electromagnetic, strong and weak nuclear). Thus, the satisfactory formulation of a quantum theory of gravity remains as one of the most important challenges of theoretical physics. Black holes on the other hand, which are solutions of Einstein's theory of general relativity, and have event horizons, serve as theoretical laboratories for testing various proposals of quantum gravity. They are believed to have entropy and temperature, understanding the microscopic origin of which is hoped to shed light on the nature of quantum gravity. Continuing to work in black hole physics, I would like to examine whether quantum entanglement between fields inside and outside a horizon can be a source of black hole entropy, and try to identify the location of the degrees of freedom which give rise to this entropy. I would also like to study possible experimental signatures of mini black holes, which have been predicted by brane world scenarios to form in future high energy colliders. These signatures may result from radiation emitted and from the shedding of angular momentum from these black holes. I also intend to study the black hole information loss problem and explore whether the techniques used in Quantum Information Science (in which too I have worked in the past) can be used in that context. Finally, I intend to diversify my research into cosmology.

在自然界的四种基本力中，只有引力没有被量子化，也没有与其他三种力（电磁力、强核力和弱核力）统一起来。因此，令人满意的引力量子理论仍然是理论物理学最重要的挑战之一。另一方面，黑洞是爱因斯坦广义相对论的解决方案，并且具有事件视界，可以作为测试各种量子引力理论的理论实验室。它们被认为具有熵和温度，理解其微观起源有望揭示量子引力的本质。继续研究黑洞物理学，我想研究视界内外场之间的量子纠缠是否可以成为黑洞熵的来源，并试图确定产生这种熵的自由度的位置。我也想研究可能的实验签名的迷你黑洞，这已经被预测的膜世界的情况下，形成在未来的高能对撞机。这些特征可能是由这些黑洞发出的辐射和角动量的脱落造成的。我还打算研究黑洞信息丢失问题，并探索量子信息科学中使用的技术（我过去也曾在量子信息科学中工作过）是否可以在这种情况下使用。最后，我打算把我的研究扩展到宇宙学。
