Rebecca Phillipson is awarded a Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship (MPS-Ascend) to conduct a program of research and education at Washington University. Dr. Phillipson plans to take advantage of upcoming large scale optical studies, like the NSF’s Vera C. Rubin Observatory Legacy Survey of Space and Time. She has demonstrated recurrence analysis methods from nonlinear dynamics are capable of distinguishing between deterministic, stochastic, and chaotic signals in X-ray Binary Stars and Active Galactic Nuclei. Dr. Phillipson plans to broaden participation in the astrophysics field in several ways. She will mentor students participating in the Pre-Major in Astronomy program which gives opportunities for students from underrepresented groups to perform cutting edge research.Phillipson’s preliminary work suggests that an ensemble study of stellar light curves, with the recurrence methods, paired with machine learning, will result in novel classifications of variable sources based on their dynamical variability. The numerical approaches open a new discovery space for detection of quasi-periodic variable objects. She will partner with the eScience Institute to develop an accessible website for the dissemination of the scientific results from her research program. A key feature of her data access plan is enabling visually impaired scientists to interact with the data by using sounds to facilitate feature detection and analysis. This approach, called sonification, uses existing software tools to map scientific data to acoustic sequences.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

丽贝卡·菲利普森（Rebecca Phillipson）被授予一项数学和物理科学，上升博士后研究奖学金（MPS-ASCEND），以在华盛顿大学进行研究和教育计划。 Phillipson博士计划利用即将进行的大规模光学研究，例如NSF的Vera C. Rubin Observatory遗产时空调查。她已经证明了来自非线性动力学的复发分析方法能够区分X射线二进制恒星中的确定性，随机和混沌信号和活性银河系核。 Phillipson博士计划以多种方式扩大对天体物理学领域的参与。她将指导参加活动前天文学计划的学生，该计划为来自代表性不足的小组的学生提供了尖端研究的机会。Phillipson的初步工作表明，基于动力学性能，将与机器学习相结合的重复曲线的恒星光曲线进行整体研究，并与机器学习相结合。数值方法为检测准周期变量对象打开了一个新的发现空间。她将与Escience Institute合作，开发一个可访问的网站，以传播其研究计划的科学结果。她的数据访问计划的一个关键特征是使视力障碍的科学家通过使用声音促进功能检测和分析来与数据互动。这种称为Sonification的方法使用现有的软件工具将科学数据映射到声学序列中。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响标准，被视为通过评估而被视为珍贵的支持。
