The Division of Chemistry supports Christopher Johnson of Yale University as an American Competitiveness in Chemistry Fellow. Dr. Johnson will work on studying the structure and dynamics of the gas-phase clusters that are thought to be important precursors in the formation of atmospheric aerosols. The PI will collaborate with scientists at the Center for Aerosol Impacts on Climate and the Environment. The ultimate goal of this research is to develop a better understanding of the fundamental chemistry and physics of atmospheric aerosol formation and growth. For his plan for broadening participation, Dr. Johnson will develop simple hands-on models for use by students and members of the public, which make clear how modern chemical instrumentation works. Research like that of Dr. Johnson is aimed at developing an improved understanding of the chemistry and physics behind the formation of atmospheric aerosols. This is an area of research for which there is currently a great deal of uncertainty. This uncertainty hinders the development of e.g. more accurate models of the climate. The efforts at broadening participation being pursued by Dr. Johnson are aimed at educating young people from underrepresented groups about modern chemical instrumentation, in the hopes of encouraging these young people to consider careers in science.

化学系支持耶鲁大学的克里斯托弗·约翰逊（Christopher Johnson）是美国化学研究员的竞争力。 约翰逊博士将研究气相簇的结构和动力学，这些气相簇被认为是大气气溶胶形成的重要前体。 PI将与气溶胶中心对气候和环境的影响的科学家合作。 这项研究的最终目标是更好地了解大气中的气溶胶形成和生长的基本化学和物理。 为了扩大参与的计划，约翰逊博士将开发简单的动手模型，以供学生和公众使用，这清楚地表明了现代化学仪器的运作方式。 像约翰逊博士这样的研究旨在对大气气溶胶形成背后的化学和物理学有了深刻的了解。 这是一个研究领域，目前存在很多不确定性。 这种不确定性阻碍了例如气候的更准确模型。 约翰逊博士进行的扩大参与的努力旨在向人类代表性不足的团体的年轻人进行有关现代化学仪器的教育，以期鼓励这些年轻人考虑科学领域的职业。
