Dr. Huterer is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at the Center for Cosmological Physics at the University of Chicago. The dominant theory behind the recent discovery of the accelerating expansion of the universe involves a mysterious component called dark energy. The nature of dark energy and the physics mechanism responsible for its existence remain one of the central questions of cosmology and particle physics. Dr. Huterer's research program will both explore existing and develop new mathematical methods aimed to understand properties of dark energy. In particular, Dr. Huterer will (1) study theory uncertainty in weak gravitational lensing, leading to the derivation of theory accuracy requirements for upcoming observational surveys, (2) build phenomenological models to help explain why dark energy becomes dominant only at low redshifts, and (3) propose new methods for studying dark energy.Dr. Huterer will also carry out an educational program of interactive lectures and activities, tailored specifically for urban middle school students at North Kenwood/Oakland Charter School on Chicago's south side. Dr. Huterer will help to develop curriculum for a cosmology unit as part of the school's General Science program, organize and teach after-school science labs, and mentor students on a weekly basis. Dr. Huturer will also help to organize the annual Yerkes Summer Institute workshops at Yerkes Observatory in Wisconsin, in which the majority of participants are urban Chicago high school students.

Huterer 博士获得美国国家科学基金会天文学和天体物理学博士后奖学金，在芝加哥大学宇宙物理中心开展研究和教育项目。最近发现的宇宙加速膨胀背后的主导理论涉及一种称为暗能量的神秘成分。暗能量的本质及其存在的物理机制仍然是宇宙学和粒子物理学的核心问题之一。 Huterer 博士的研究计划将探索现有的并开发新的数学方法，旨在了解暗能量的特性。特别是，Huterer 博士将（1）研究弱引力透镜中的理论不确定性，从而推导即将到来的观测调查的理论准确性要求，（2）建立唯象模型以帮助解释为什么暗能量仅在低红移时占主导地位，以及（3）提出研究暗能量的新方法。胡特勒还将开展互动讲座和活动的教育计划，专为芝加哥南区北肯伍德/奥克兰特许学校的城市中学生量身定制。 Huterer 博士将帮助开发宇宙学单元的课程，作为学校普通科学计划的一部分，组织和教授课外科学实验室，并每周指导学生。胡图尔博士还将帮助在威斯康星州耶克斯天文台组织一年一度的耶克斯暑期研究所研讨会，其中大多数参与者是芝加哥市区的高中生。
