Reference excerpt

Professor Nils Gunnar Hansson von Heijne (born 10 June 1951 in Gothenburg) is a Swedish scientist working on signal peptides, membrane proteins and bioinformatics at the Stockholm Center for Biomembrane Research at Stockholm University.

Education Von Heijne graduated 1975 with a Master of Science degree in chemistry and chemical engineering from the Royal Institute of Technology (KTH). He then became a doctoral student in theoretical physics at KTH, in a research group focussing on statistical mechanics and theoretical biophysics, and was awarded his PhD in 1980. In 1983 he was made docent in theoretical biophysics at KTH, where he remained until 1988. 1982–1985 he was active as a science reporter at Sveriges Radio. 1989–1994 he was active at Karolinska Institutet, and in 1994 he was made a professor in theoretical chemistry at Stockholm University.

Research Von Heijne's research primarily concerns membrane proteins, and he is one of the most cited Swedish scientists in the areas of biochemistry and molecular biology. He heads the Center for Biomembrane Research at Stockholm University.

Awards In 2012 he was awarded the Accomplishment by a Senior Scientist Award by the International Society for Computational Biology. von Heijne is a member of the Royal Swedish Academy of Sciences since 1997 and a member of the Nobel Committee for Chemistry from 2001 to 2009, and the Committees chairman from 2007 to 2009. In 2008, he received an honorary doctorate at Åbo Akademi.

Worked examples

Example 1 — a first encounter with Gunnar von Heijne

Start with the simplest possible case. Write down what Gunnar von Heijne 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 Gunnar von Heijne 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 Gunnar von Heijne 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 Gunnar von Heijne

In research: Gunnar von Heijne 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 Gunnar von Heijne 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: Gunnar von Heijne is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1951 births, Academic staff of Stockholm University, Academic staff of the Karolinska Institute, so understanding it makes those chapters shorter.
In everyday life: Look for Gunnar von Heijne 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.
