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.

职业生涯：探索介形类（甲壳纲）宏观进化分歧时间的化石和分子估计的一致性“PI-托德H。奥克利PI将对介形虫（Oakley）众多进化谱系的起源时间进行实证研究，介形虫是一种具有良好化石记录的甲壳类动物。一个主要的目标是研究化石和分子分歧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。 该项目包括从众多介形虫的五个基因序列中收集新数据，这些基因序列被选为更大的候选基因组中最像时钟的基因。 为了确保平衡的方法，PI（其主要培训是分子生物学）将与博士后研究人员合作，主要培训是形态学/分类学和古生物学。这项研究将对理解进化分歧时间估计方法产生广泛的影响，并为这些研究提供重要的新数据。 这些研究是了解生物与气候变化等环境因素之间关系的先决条件。 这些结果将作为PI研究介形类进化现象的职业基础。 此外，PI正在开发一个教学机会网络。首先，研究成果将被纳入PI的初级本科课程，这也将在许多其他方面得到改善。 该研究还包括具体的，模块化的本科生研究和社区推广项目。 PI是多个组织的积极参与者，这些组织促进科学中代表性不足的群体的进步，经常从这些组织中招募人员以协助研究和推广。
