王力乐，北京大学科维理天文与天体物理研究所研究员、tenure track 助理教授，入选国家级海外人才计划。2012 年本科毕业于清华大学数理基础科学班，2018 年博士毕业于美国普林斯顿大学天体物理科学系，2018--2021 年于美国 Flatiron Institute 计算天体物理中心进行博士后研究。主要研究方向为：行星形成、原行星盘、系外行星大气，以及计算天体物理、高性能计算。Protoplanetary disks (PPDs) are one of the most complicated types astrophysical systems that involve multi-scale multiphysics. Due to the complication, most PPD problems  have to be solved numerically. The speaker will briefly overview some critical issues he met and tried to solve in computational studies on PPDs, discussing the advanced computational methods and their applications in PPDs, exoplanet atmospheres, and probably other fields of research.
