Gabriel Leung

Gabriel Leung is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Gabriel Leung rather than just read about it. In short: Gabriel Matthew Leung (Chinese: 梁卓偉; Jyutping: Loeng4 Coek3 Wai5, born 6 November 1972) is a Hong Kong physician and epidemiologist, currently serving as the executive director (Charities and Community) of the Hong Kong Jockey Club. From 2013 to 2022, he was the longest-serving dean of medicine at the University of Hong Kong, where he was also the inaugural Helen and Francis Zimmern Professor in Population Health.

Key takeaways

Gabriel Leung belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Gabriel Leung to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Gabriel Leung from memory before moving on to harder problems.

Reference excerpt

Gabriel Matthew Leung (Chinese: 梁卓偉; Jyutping: Loeng4 Coek3 Wai5, born 6 November 1972) is a Hong Kong physician and epidemiologist, currently serving as the executive director (Charities and Community) of the Hong Kong Jockey Club. From 2013 to 2022, he was the longest-serving dean of medicine at the University of Hong Kong, where he was also the inaugural Helen and Francis Zimmern Professor in Population Health. Formerly, he was Hong Kong's first undersecretary for food and health and fifth director of the Office of the Chief Executive at the Government of Hong Kong.

Early life and education Leung was born in Hong Kong and studied at Wah Yan College. His maternal grandfather was British. He continued his education at Stonyhurst College in Lancashire, England (1986–1989) and Crescent School in Canada (1990). His family moved to Canada when he was 13 in Form 2 (equivalent to Year Eight in England, Wales, Australia and New Zealand), due to his father's job with a multinational company, Leung undertook his undergraduate education at the University of Western Ontario, majoring in chemistry and minoring music. He then entered the medical school at same university, initially majoring in neurosurgery, eventually switching to public health and completed his family medicine residency training at the University of Toronto. He then received his Master of Public Health degree from Harvard University in 1999, and earned a research doctorate (Doctor of Medicine) at the University of Hong Kong.

Career In 1999, Leung joined the University of Hong Kong (HKU) Faculty of Medicine (now the Li Ka Shing Faculty of Medicine) as an assistant professor in the Department of Community Medicine (now part of the School of Public Health), and became an associate professor when the School of Public Health was formed in 2004. During the SARS outbreak, he established and directed the Infectious Disease Epidemiology Group. He was a Takemi Fellow at Harvard University from 2004 to 2005, and, after returning to Hong Kong, expanded the Children of 1997 study together with Catherine Mary Schooling, which followed "the majority of all babies born in Hong Kong during April and May 1997", into a life-course epidemiological study. Leung was promoted to full professor in 2006 at the age of 33, one of the youngest in HKU's history. He also served as the vice president and censor in public health medicine at the Hong Kong College of Community Medicine from 2006 to 2008. In 2008, Leung left academia and joined the Government of Hong Kong as the first undersecretary for food and health, during which he led the government's response in the 2009 swine flu H1N1 pandemic. He held the position until 2011 when he was appointed the director of the Office of the Hong Kong Chief Executive. When his term at the government ended, Leung returned to HKU in 2012 as the head of the Department of Community Medicine until 2013, when the department was incorporated into the School of Public Health, and the inaugural master of Chi Sun College. He was also the acting director of the School of Public Health during this period. In 2013, Leung was appointed as the 40th dean of the HKU Li Ka Shing Faculty of Medicine and chair professor of public health. At the age of 40, he was the second youngest dean ever appointed at the HKU medical faculty. During his deanship, the Faculty of Medicine launched the Springboard Scholarships and Second Chance Scholarship schemes to recruit students from more diverse backgrounds. A number of major changes to the faculty took place under Leung's watch, including:

Worked examples

Example 1 — a first encounter with Gabriel Leung

Start with the simplest possible case. Write down what Gabriel Leung claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Gabriel Leung before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Gabriel Leung ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Gabriel Leung

In research: Gabriel Leung appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Gabriel Leung in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Gabriel Leung is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1972 births, Academic staff of the University of Hong Kong, Alumni of the University of Hong Kong, so understanding it makes those chapters shorter.
In everyday life: Look for Gabriel Leung outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
