Theoretical studies in gravitational physics and elementary particle physics will be conducted. Studies will include further developing field theories associated with large symmetries for gravitational physics, exploring the relationships of string theories to nuclear matter and applying theories developed from string symmetries to the early universe and cosmology. These studies may provide information and ideas concerning some of the issues that are pressing in the research in gravity, cosmology and nuclear physics. To date there is no satisfactory explanation available for all the interactions of gravity with elementary particles or for gravity at large scales. Also further studies of the relationship of string theory to nuclear physics will help provide a mathematical framework for better predictions in nuclear physics. Understanding these fundamental interactions at a rigorous mathematical and computational level are important for further understanding of the nature of the fundamental forces of nature. The project has a wide variety of problems that can be solved which include advanced undergraduates and graduate students. This affords opportunities for younger students in physics to get early exposure to issues in nuclear physics, string theory and problems related to gravitation. The PI is also the faculty coordinator of the "Hawkeyes On Science" outreach program for the Department of Physics and Astronomy at the University of Iowa, is the organizer and creator of the Iowa City chapter of "Cafe Scientifique", and a volunteer tutor for the Iowa City Community School District.

将进行引力物理和基本粒子物理的理论研究。研究将包括进一步发展与引力物理大对称性相关的场论，探索弦理论与核物质的关系，以及将从弦对称发展而来的理论应用于早期宇宙和宇宙学。这些研究可能提供有关重力、宇宙学和核物理研究中一些紧迫问题的信息和想法。迄今为止，对于重力与基本粒子的所有相互作用或大尺度的重力，还没有令人满意的解释。此外，对弦理论与核物理关系的进一步研究将有助于为核物理更好的预测提供数学框架。在严格的数学和计算水平上理解这些基本相互作用对于进一步理解自然基本力的本质非常重要。该项目可以解决各种各样的问题，包括高年级本科生和研究生。这为物理学专业的低年级学生提供了早期接触核物理、弦理论和引力相关问题的机会。 PI 也是爱荷华大学物理与天文学系“Hawkeyes On Science”外展计划的教员协调员，“Cafe Scientifique”爱荷华市分会的组织者和创建者，以及爱荷华市社区学区的志愿者导师。
