Dr. Berlind will carry out a program to help strengthen two critical "pipelines." The first pipeline starts with measurements of galaxy clustering in redshift surveys, such as the Sloan Digital Sky Survey (SDSS), and ends in a physical understanding of cosmology and galaxy formation. The pipeline involves obtaining unbiased estimates of statistical and systematic errors, refining theoretical models used to fit the data, performing the fitting, and interpreting the results. A key tool required for every step in the pipeline is cosmological N-body simulations and associated mock galaxy catalogs. Dr. Berlind will complete the LasDamas simulations project and use it to enable the joint modeling of galaxy two-point, three-point, and group statistics in the SDSS. This should yield the strongest constraints to date on the relationship between galaxy properties and their underlying dark matter halos. The LasDamas simulations will also be used to study the detailed properties of dark matter halos with unprecedented precision. The second pipeline is the one that produces professional astronomers from underrepresented minority groups. This pipeline has "leaks" at the K-12, undergraduate, and graduate parts, resulting in a very poor production rate of minority PhDs. Dr. Berlind will put in place a series of programs designed to patch this leaky pipeline. These include (1) creating scholarships for K-12 students to attend summer camps at Dyer Observatory, (2) creating a scholarship to support undergraduate physics students at Fisk University, (3) running an undergraduate summer research internship, and (4) designing and teaching an intensive workshop on statistics and data analysis for Fisk-Vanderbilt Bridge Masters students.

柏林德博士将实施一项计划，以帮助加强两个关键的“管道”。" 第一条管道从测量红移巡天中的星系集群开始，例如斯隆数字巡天（SDSS），并以宇宙学和星系形成的物理理解结束。 管道包括获得统计和系统误差的无偏估计，改进用于拟合数据的理论模型，执行拟合并解释结果。 管道中每一步所需的关键工具是宇宙学N体模拟和相关的模拟星系目录。 Berlind博士将完成LasDamas模拟项目，并使用它来实现SDSS中星系两点、三点和组统计的联合建模。 这将产生迄今为止对星系属性与其潜在暗物质晕之间关系的最强约束。 LasDamas模拟还将用于以前所未有的精度研究暗物质晕的详细特性。第二条管道是从代表性不足的少数群体中培养专业天文学家的管道。 这条管道在K-12、本科和研究生部分都有“漏洞”，导致少数民族博士的产出率非常低。 柏林德博士将实施一系列旨在修补泄漏管道的计划。 这些措施包括（1）创建奖学金K-12学生参加戴尔天文台夏令营，（2）创建奖学金，以支持本科物理学生在菲斯克大学，（3）运行本科夏季研究实习，以及（4）设计和教学密集的统计和数据分析研讨会菲斯克-范德比尔特桥硕士学生。
