This award represents the transfer of CAREER-grant funding for the research of Professor Stephon Alexander from Haverford University to Dartmouth College.The search for a quantum theory of gravity has seen progress with the advent of string theory and loop quantum gravity, but both lack direct contact with experiment. The PI proposes a five-year plan that can potentially resolve fundamental problems in cosmology and particle physics by developing new models that arise from theories beyond the standard model and quantum gravity. Additionally, he proposes new observational schemes to test these models. The PI's long-term research plans over the next five years focus on two themes. One is at the interface of particle physics and cosmology where he hopes to look at the consequences for LHC physics of his new model that unifies gravity with the electroweak force. He will also investigate the phenomenological consequences of a Supersymmetric extension of this model. The second area concerns the nature of the cosmological singularity. The PI has proposed several novel theories based on modifying gravity and will also consider the experimental consequences of these models. This project is also envisioned to have significant broader impacts. The outreach part of this CAREER project will consist of the PI giving a two-week course on Music and the Cosmos, which will be hands on presentation on the physics of sound and musical instruments. These lectures will be presented to urban high school students. The PI will also serve as both a research and long-term career mentor for two minority undergraduate students each year, by creating two summer research positions in his group through this award.

该奖项代表了从哈弗福德大学（Haverford University）到达特茅斯学院（Haverford University）的斯蒂芬·亚历山大（Stephon Alexander）研究的职业授予资金的转移。寻求量子的重力理论随着弦乐理论和循环量子引力的出现而取得了进步，但两者都缺乏与实验的直接接触。 PI提出了一个五年的计划，该计划可以通过开发源自超出标准模型和量子重力的理论而产生的新模型来潜在地解决宇宙学和粒子物理学中的基本问题。此外，他提出了新的观察方案来测试这些模型。 PI在未来五年内的长期研究计划集中于两个主题。一个人是在粒子物理和宇宙学的界面上，他希望研究其新模型的LHC物理学的后果，该物理学将重力与electroweak力统一。 他还将研究该模型超对称扩展的现象学后果。 第二个领域涉及宇宙学奇异性的性质。 PI基于修饰的重力提出了几种新型理论，还将考虑这些模型的实验后果。 还设想该项目具有更广泛的影响。 该职业项目的外展部分将包括PI提供为期两周的音乐和宇宙课程，这将是关于声音和乐器物理学的演示。这些讲座将介绍给城市高中生。 PI每年还将通过该奖项在小组中创建两个夏季研究职位，既可以为两名少数本科生的研究和长期职业导师。
