Dr. Marshall Perrin is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at the University of California-Los Angeles. Dr. Perrin will combine the observational study of circumstellar disks using present instrumentation with the development of a powerful new instrument for future, higher contrast disk observations. His research program will include: (1) measurement of disk structure and grain growth around several newly discovered circumstellar disks through the combination of high-contrast disk imaging and numerical modeling; (2) integral field spectroscopy of bipolar outflows near their origin in circumstellar disks to quantify physical conditions in the jets and constrain theories of jet acceleration; and (3) participation in the development of the next generation of high-contrast disk imagers--the sensitive polarimetry mode of the Gemini Planet Imager. This combined observational and instrumental approach to high-contrast imaging will advance both our present understanding of circumstellar disks and our technological capacity for further studies.Dr. Perrin will also develop and teach an introductory astrophysics course for astronomy majors that incorporates best practices from recent educational research and will volunteer with Project ASTRO to bring astronomy into elementary-school classrooms. Dr. Perrin's program of education and outreach is designed to increase the participation of women and underrepresented minorities in the scientific community.

马歇尔·佩林（Marshall Perrin）博士被授予NSF天文学和天体物理学博士后奖学金，以在加利福尼亚洛杉矶大学进行研究和教育计划。 Perrin博士将使用当前的仪器将观察性研究结合在一起，并开发了一种强大的新工具，以供将来，更高的对比度观测值。他的研究计划将包括：（1）通过高对比度磁盘成像和数值建模的结合，测量了几个新发现的杂质磁盘周围的磁盘结构和谷物生长； （2）双极磁盘附近的双极外流的整体场光谱法，以量化喷气机中的物理条件并约束射流加速度的理论； （3）参与下一代高对比度磁盘成像器的发展 - 双子星球成像仪的敏感偏光模式。这种高对比度成像的观测和工具方法将提高我们目前对偶然磁盘的理解以及我们进一步研究的技术能力。佩林还将开发和教授天文学专业的天体物理学课程，其中结合了最近的教育研究的最佳实践，并将自愿参加Astro Project，将天文学带入小学课堂。佩林博士的教育和外展计划旨在增加妇女和代表性不足的少数民族在科学界的参与。
