The proton is one of the building blocks of everyday matter, with protons in the core of every atom. The proton is in turn made of subnuclear particles known as quarks and gluons. The project supported by this award will improve our understanding of the proton's internal structure, with a focus on the dynamical behavior of the constituent quarks. High-energy particle accelerator facilities at Fermi National Accelerator Laboratory (Fermilab) will be used to perform the research. A beam of protons will be accelerated to high energy and strike a liquid hydrogen target; the nucleus of a hydrogen atom is comprised of a single proton. Measurement of the particles produced in the collisions will provide information on the behavior of the quarks in their parent protons.The efforts supported by this award will additionally serve to increase diversity among young scientists trained as nuclear physicists. Training the next generation of nuclear physicists is critical to maintain expertise relevant to the nation's energy and defense needs and to continue advancing both applied and non-applied research in nuclear physics and technology. In each year of this award a student from Mount Holyoke College, an undergraduate institution for women, will be given the opportunity to perform summer research in nuclear physics at Fermilab. Furthermore, this award will provide tuition, salary, and travel support for an African-American graduate student. In addition to supporting his dissertation research, he will receive support to travel once per semester to his alma mater, Howard University, a historically black university, to speak with current physics undergraduates about his experience and progress pursuing a Ph.D. in nuclear physics.

质子是日常物质的基础之一，质子是每个原子的核心。 质子反过来由称为夸克和胶子的亚核颗粒制成。 该奖项支持的项目将提高我们对质子内部结构的理解，重点是组成夸克的动态行为。 费米国家加速器实验室（Fermilab）的高能粒子加速器设施将用于进行研究。 一束质子将加速到高能并撞击液态氢靶。氢原子的核由单个质子组成。 对碰撞中产生的颗粒的测量将提供有关其母质子中夸克行为的信息。该奖项支持的努力还将增加受过核物理学家培训的年轻科学家的多样性。 培训下一代核物理学家对于维持与国家能源和国防需求相关的专业知识至关重要，并继续推进核物理和技术中的应用和非应用研究。 在该奖项的每一年，霍利奥克山学院的一名学生（一家妇女的本科机构）将有机会在费米拉布（Fermilab）进行夏季核物理学研究。 此外，该奖项将为非裔美国研究生提供学费，薪水和旅行支持。 除了支持他的论文研究外，他还将获得每学期旅行一次前往母校，历史悠久的黑人大学一次旅行的支持，与当前的物理学大学生有关他的经验和攻读博士学位的进步。在核物理学中。
