Dr. 埃里克威尔斯的研究工作集中在理解和控制强激光场中的分子动力学.

超短激光脉冲的特性表明，它们可能被用来直接影响化学反应:激光场施加的力可以与将分子结合在一起的电力相媲美, 和 pulse can be turned on and off before the molecule will move significantly. 因此, 将定制的激光脉冲精确应用于单个分子，可能使目标分子的修饰成为可能, 所期望的方式. The Augustana atomic, molecular & 光学(AMO)物理小组开发了一种将分子片段的三维离子成像耦合到反馈回路的方法，该方法使用自适应学习算法来设计可以控制特定分子过程的激光脉冲, such as hydrogen migration and bond rearrangement.

Augustana students carry out this work using the laser facilities of the J.R. 麦克唐纳实验室 at Kansas State University as part of a long-standing collaboration between the two institutions.

作为12bet游戏平台AMO工作的一部分，32名本科生共同撰写了22篇不同的文章. The research is supported by the National Science Foundation. 井’ sabbatical leaves at Kansas State have been supported by the U.S. 能源部.

Dr. 内森·格劳(内森格劳)的研究重点是了解原子核中质子和中子结合以及太阳能量产生的强核力.

He and his students do this with collisions of nuclei at high speeds. Augustana is a member institution of several experiments located at Brookhaven National Laboratory on Long Island, New York: the 凤凰合作, sPHENIX协作 和 ePIC Collaboration. 这些合作项目建造了大型高能物理探测器，在对撞机加速器上收集数据. The PHENIX experiment collected data until 2016 at the Relativistic Heavy Ion Collider. sPHENIX探测器是后续探测器，将在2023年采集第一批数据. The ePIC detector is the project detector for the future 电子离子对撞机.

格劳 has mentored dozens of students over the past decade. 他的研究一直得到英国国家科学与技术委员会本科院校研究项目(RUI)的资助 National Science Foundation 自2013年以来.

Dr. Drew Alton's research is focused on weakly interacting particles, lately in the form of Dark Matter, but before that in terms of understanding the W/Z boson and neutrino interactions.

He helps preparations for the new DarkSide-20k 该项目目前正在意大利建设，预计将于2026年投入运营. DarkSide-50, its predecessor, operated for about five years in Gran Sasso National Laboratory 在意大利. Alton and various AU students worked on developing a precise energy measurement, 哪些可以用来了解背景，检验实验的稳定性和数据质量.

Alton has also recently joined the Deep Underground Neutrino (沙丘) experiment, which is expected to begin operating in approximately 2030.
