Hear from Our Student

Ho Ling Holly CHAN
BSc graduate (major in Earth System Science)
“Majoring in Earth System Science completely reshaped my life philosophy. Exploring the intricate connections between the atmosphere, hydrosphere, geosphere, biosphere, and anthroposphere, the major built a comprehensive worldview. Integrating hands-on observations, laboratory data analysis and overseas fieldwork sharpened my scientific reasoning skills, linking micro-scale reactions to macro-scale global systems across immense temporal scales. HKU’s flexibility also allowed me to connect diverse electives to my major, truly deepening my planet-wide understanding.”

Chi Hang HUI
BSc graduate (major in Earth System Science)
“One of the highlights of my studies was a series of overseas field trips, where I embarked on journeys to remote places. Scientific knowledge was not the only asset I gained from my studies, as the Earth System Science Major provided me with a holistic experience.”
