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：探索介形类（甲壳类）宏观进化分歧时间的化石和分子估计的一致性”PI-Todd H. Oakley 该 PI 将对介形类（一种具有出色化石记录的甲壳类动物）众多进化谱系的起源时间进行实证研究。主要目标是检查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、统计和该项目包括从众多介形类的五个基因序列中收集新数据，这些基因被选为更大的候选基因组中最像时钟的基因，为了确保方法的平衡，PI（其主要培训是分子系统学）。 ）将与接受过形态学/分类学和古生物学初级培训的博士后研究人员合作。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。 这些研究是理解生物体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 调查介形类进化现象的职业生涯奠定基础。 此外，PI 正在开发一个教学和学习机会网络。首先，研究成果将融入到PI的本科初级课程中，并在其他方面进行改进。 该研究还包括用于本科生研究和社区外展的具体模块化项目。 PI 是多个促进科学领域代表性不足群体进步的组织的积极参与者，经常从这些组织招募人员来协助研究和推广。
