Reference excerpt

Nga Lee Ng is the Love Family Professor at the Georgia Institute of Technology, holding appointments in both the School of Chemical and Biomolecular Engineering and the School of Earth and Atmospheric Sciences. Her research focuses on atmospheric chemistry, particularly in the study of organic aerosols and their effects on air quality, climate, and human health.

Education and early career Ng earned her Bachelor of Engineering degree in Chemical and Environmental Engineering from the Hong Kong University of Science and Technology in 2002. She was an exchange student in Chemical Engineering at the University of Minnesota from 2000 to 2001. She then pursued her graduate studies at the California Institute of Technology, where she completed her M.S. in Chemical Engineering in 2004 and her Ph.D. in 2007 under the supervision of John H. Seinfeld and Richard C. Flagan. Following her Ph.D., Ng worked as a postdoctoral scholar at the California Institute of Technology (2007-2008) and then as a postdoctoral scientist at Aerodyne Research (2008-2010). She continued at Aerodyne Research as a senior scientist from 2010 to 2011.

Research and career Ng joined the Georgia Tech faculty in 2011. Her research focuses on the chemistry of atmospheric aerosols, including their formation, transformation, and impacts. Her work has provided insights into the role of organic aerosols in air quality and climate change. She employs advanced analytical techniques and modeling approaches to study the sources, processes, and effects of particulate matter and other air pollutants. She was the lead principal investigator on a $12M National Science Foundation (NSF) grant awarded in 2021 to establish the Atmospheric Science and Chemistry mEasurement NeTwork (ASCENT), which aims to collect real-time measurements of atmospheric particulates' chemical composition and properties at 12 different sites around the United States. She received a Love Family endowed professorship at Georgia Tech in 2022. Ng has held several editorial positions, including Editor-in-Chief of ACS Environmental Science & Technology Air since 2023, and she has served on the ACS Earth and Space Chemistry and Scientific Reports editorial boards.

Worked examples

Example 1 — a first encounter with Nga Lee (Sally) Ng

Start with the simplest possible case. Write down what Nga Lee (Sally) Ng claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Nga Lee (Sally) Ng 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 Nga Lee (Sally) Ng 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 Nga Lee (Sally) Ng

In research: Nga Lee (Sally) Ng appears in chemistry 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 Nga Lee (Sally) Ng 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: Nga Lee (Sally) Ng is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aerosol scientists, Alumni of the Hong Kong University of Science and Technology, American women chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Nga Lee (Sally) Ng 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.
