The academic exchange facilitated through the HK Laureate Forum will be an unparalleled opportunity for me to meet and interact with Shaw Laureates and other fellow young scientists. My field of astronomy is currently undergoing a big leap, particularly in data processing, and new innovative methods to process and interpret the data will be required. I look forward to learning how the Shaw Laureates continue to remain at the forefront of their fields, especially in astronomy. Additionally, with the global challenges currently facing us (e.g., climate change, big data), cross-disciplinary thinking and approaches will be required. The Forum offers a unique platform to broaden my scientific horizons and form lasting connections with the next generation of leaders to tackle the challenges. Engaging with the Shaw Laureates will challenge my perspectives, inspire new ways of thinking, and offer insights that will inform my own approach to research. Having lived and studied in five countries, I deeply value diverse perspectives and constantly engage in cross-cultural dialogue in pushing scientific progress. I am especially excited about the thematic discussions at the Forum on current trending topics, as well as learning about the vibrant scientific and innovation hubs in Hong Kong.

Fast radio bursts (FRBs) are bright astrophysical, extragalactic, and millisecond radio flashes of yet unknown origins. While the vast majority of FRB sources have only been observed once, a small fraction (~3%) have been found to exhibit repeat bursts. Polarimetry provides us with a powerful tool to probe the emission mechanisms and local magneto-ionic environments of these enigmatic FRBs. I will present an overview of the polarization properties of nearly 2,000 FRBs detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) between 1 July 2019 and 15 September 2023, operating at 400-800 MHz. These FRBs originate from over 1,500 unique sources and represent the largest catalog of FRB polarimetric measurements from a single instrument to date. I will highlight some key results from the catalog, including a comparison of polarimetric properties between repeating and non-repeating FRBs, the diversity of polarization angle swings in the bursts, as well as FRBs with high Faraday rotation measures that suggest extreme local environments with strong magnetic fields and/or high electron number densities. I will conclude with a discussion of the implications for our understanding of FRB emission models and their environments.
