R.M. Petrie Prize Lecture

 The Petrie Lecture is an invited discourse by an outstanding astrophysicist which is held at Annual Meetings of the Society in alternate (odd-numbered) years, in memory of the significant contributions to astrophysical research by the late Robert M. Petrie. The Petrie Lecture originated under the auspices of the Canadian Committee for the IAU, prior to the existence of the Society, and was revived by the Society in 1977 as a regular event. Nominations for the Petrie Lecture can be made by submitting the name of a nominee to the Awards committee at any time, and should originate from at least two CASCA members in good standing. Nominations for the 2023 Lecturer should be received by January 15 2023.

2023 Petrie Prize Lecture

CASCA is pleased to announce Dr. You-Hua Chu, Distinguished Research Fellow at the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA), as the 2023 R.M Petrie Prize Lecturer.

Dr. You-Hua Chu is an international leader in the studies of the interstellar medium, star formation and feedback, supernova progenitors and environments, and dusty disks around white dwarfs. She is an expert on both the Milky Way and Magellanic Clouds, having extensively researched the whole diverse population of these galaxies throughout her career. She makes use of both multi-wavelength observations (radio, infrared, optical and X-ray) and modelling to address fundamental questions about the fate of stars, their interaction with the interstellar medium and the evolution of galaxies in the nearby Universe. Throughout her career, Dr. You-Hua Chu has demonstrated outstanding leadership in the astronomical community on multiple continents and was notably the first woman to serve as Director of ASIAA.

CASCA is honoured to have Dr. You-Hua Chu give the Petrie Prize lecture.
