CAREER: Exploring Congruence of Fossil and Molecular Estimates of Macroevolutionary Divergence Times in Ostracoda (Crustacea)"PI- Todd H. OakleyThe PI will conduct an empirical study of origination times of numerous evolutionary lineages of Ostracoda, a crustacean group with an excellent fossil record. A primary goal is to examine causes of observed differences between fossil and molecular divergence estimates, while considering molecular, statistical and paleontological explanations. The project includes collection of new data from five gene sequences from numerous Ostracoda, selected as the most clock-like genes of a larger panel of candidate genes. To ensure a balanced approach, the PI (whose primary training is in molecular phylogeny) will collaborate with postdoctoral researchers with primary training in morphology/taxonomy and paleontology.This study will have broad implications for understanding methods of evolutionary divergence time estimation, and produce important new data for these studies. These studies are prerequisites for understanding the relationship between organisms and environmental factors like climate change. The results will serve as a foundation for the PI's career investigating evolutionary phenomena in Ostracoda. In addition, the PI is developing a network of opportunities for teaching and learning. First, the research results will be integrated into the PI's primary undergraduate course, which will also be improved in numerous other ways. The research also includes specific, modular projects for undergraduate research and community outreach. The PI is an active participant in multiple organizations that promote advancement of under-represented groups in science, often recruiting from these organizations to assist in research and outreach.

职业：探索介形虫（甲壳纲）宏观进化分化时间的化石和分子估计的一致性PI- Todd H. oakley PI将对具有优秀化石记录的甲壳纲群体介形虫的许多进化谱系的起源时间进行实证研究。主要目标是研究化石和分子差异估计之间观察到的差异的原因，同时考虑分子、统计和古生物学的解释。该项目包括收集来自众多介形虫的五个基因序列的新数据，这些基因序列被选为更大的候选基因面板中最像时钟的基因。为了确保平衡的方法，PI（其主要训练是分子系统发育）将与形态学/分类学和古生物学的博士后研究人员合作。本研究将对理解进化发散时间估计方法具有广泛的意义，并为这些研究提供重要的新数据。这些研究是理解生物与气候变化等环境因素之间关系的先决条件。研究结果将为PI今后研究介形虫类进化现象奠定基础。此外，PI正在开发一个教学和学习机会网络。首先，研究成果将被整合到PI的初级本科课程中，并将在许多其他方面进行改进。该研究还包括针对本科生研究和社区推广的具体模块化项目。PI积极参与了多个组织，这些组织促进了科学界代表性不足群体的进步，经常从这些组织中招募人员来协助研究和推广。
