This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Merryn Tawhai rather than just read about it. In short: Merryn Tawhai is a New Zealand engineering scientist. She is a professor at the University of Auckland, director of the Auckland Bioengineering Institute, where she was a fellow from 2002, and a former director of MedTech CoRE.

Key takeaways

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

Reference excerpt

Merryn Tawhai is a New Zealand engineering scientist. She is a professor at the University of Auckland, director of the Auckland Bioengineering Institute, where she was a fellow from 2002, and a former director of MedTech CoRE. She is known for the development of mathematical models of the lungs that will help scientists understand differences between physiologically normal lungs and the pathological changes that might occur in a disease. She was inducted into the International Academy of Medical and Biological Engineering in June 2018. In November 2018, Tawhai was elected a Fellow of the Royal Society of New Zealand.

Life When Tawhai was in high school, her favorite subjects were mathematics and biology. In 2001, she graduated with a PhD in engineering physics from the University of Auckland. Her doctoral thesis, supervised by Andrew Pullan and Peter Hunter, was titled An anatomically based mathematical model of the human lungs, applied to gas mixing and water vapour and heat transport. She had two children during her PhD studies. Following her PhD studies, Tawhai was a research fellow at the American Institute for Medical and Biological Engineering beginning in 2002. In 2013, Tawhai was appointed deputy director of the Auckland Bioengineering Institute (ABI). In 2015, Tawhai was appointed deputy director, and then from 2018 to 2021 director, of the Medical Technologies Centre of Research Excellence (MedTech CoRE). She remains part of the research network of this organisation. In 2023, Tawhai was appointed director of the Auckland Bioengineering Institute (ABI). In May 2025 Tawhai was announced as an inaugural member of the Prime Minister's Science and Technology Advisory Council, which was established to advise government on funding priorities in New Zealand science, including identifying areas that could receive less funding.

Awards In 2016, Tawhai was awarded the MacDiarmid Medal by the Royal Society of New Zealand, and the following year she was named one of the Royal Society Te Apārangi's "150 women in 150 words", celebrating women's contributions to knowledge in New Zealand. Tawhai is a Fellow of the International Academy of Medical and Biological Engineering, and a Fellow of the American Institute for Medical and Biological Engineering.

Worked examples

Example 1 — a first encounter with Merryn Tawhai

Start with the simplest possible case. Write down what Merryn Tawhai 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 Merryn Tawhai 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 Merryn Tawhai 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 Merryn Tawhai

In research: Merryn Tawhai 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 Merryn Tawhai 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: Merryn Tawhai is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century births, Academic staff of the University of Auckland, Fellows of the American Institute for Medical and Biological Engineering, so understanding it makes those chapters shorter.
In everyday life: Look for Merryn Tawhai 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.
