Reference excerpt

Helen Mary Heffernan is a New Zealand microbiologist, specialising in antibiotic resistance. In 2020, she was appointed a Companion of the New Zealand Order of Merit, for services to health. The Institute of Environmental Science and Research awarded Heffernan their Lifetime Achievement Award in 2018.

Academic career Heffernan earned a Bachelor of Science with Honours from the University of Otago. She worked at New Zealand's National Health Institute and the Institute of Environmental Science and Research (ESR), a Crown Research Institute. Heffernan's research involved the development of cold chain standards, which are important for the safe management and storage of vaccines. She also carried out surveillance for infectious diseases, allowing the rate of spread of antimicrobial resistance to be slowed. Heffernan's research was the basis for vaccine programmes against haemophilus influenzae type b, pneumococcus and meningococcus. Heffernan was a member a number of national committees, including the National Antimicrobial Committee, the Ministry for Primary Industries' Technical Advisory Group, and the Ministry of Health's Pneumococcal Surveillance Advisory Group. She spoke about New Zealand's place in the 'global antimicrobial crisis' at the One Health symposium in 2017. She also represented New Zealand at regional meetings in the Pacific, and at the World Health Organization's workshop on Antimicrobial Resistance Surveillance.

Honours and awards In the 2020 New Year Honours, Heffernan was appointed a Companion of the New Zealand Order of Merit, for services to health. On her appointment, Heffernan asked New Zealanders to play their part to reduce antibiotic resistance, saying, "While antibiotics are essential medicines to treat bacterial infections, we overuse and misuse them and this contributes to resistance". On her retirement in 2018, after a 43-year career, ESR awarded Heffernan their Lifetime Achievement Award.

Worked examples

Example 1 — a first encounter with Helen Heffernan

Start with the simplest possible case. Write down what Helen Heffernan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Helen Heffernan 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 Helen Heffernan 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 Helen Heffernan

In research: Helen Heffernan appears in biology 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 Helen Heffernan 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: Helen Heffernan is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companions of the New Zealand Order of Merit, Living people, New Zealand microbiologists, so understanding it makes those chapters shorter.
In everyday life: Look for Helen Heffernan 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.
