Reference excerpt

John Hagan Pryce Bayley FRS, FLSW (born 13 February 1951) is a British scientist, who holds the position of Professor of Chemical Biology at the University of Oxford.

Life and education Bayley was educated at The King's School, Chester and Uppingham School, before going to Balliol College, Oxford in 1970 and Harvard University, where he was awarded a Ph.D. in 1979. Originally from Wales, he spent much of his early career between the United Kingdom and the United States.

Research Bayley's research is largely based on the study and engineering of transmembrane pore-forming proteins, as well as interests in chemical signal transduction and biomolecular materials. He is the co-founder of Oxford Nanopore Technologies Ltd. Bayley's research includes work on the pore-forming protein alpha haemolysin engineered for sensing has been highly cited.

Career Following his PhD, Bayley completed postdoctoral research at Massachusetts Institute of Technology. He previously held appointments at Columbia University, University of Massachusetts Medical School, and Texas A&M University. Bayley has been based at the University of Oxford since 2003 and is a fellow of Hertford College, Oxford.

Awards and honours Bayley was elected a Fellow of the Royal Society in 2011. His nomination reads Hagan Bayley's achievements lie at the interface between chemistry and biology. He has used protein chemistry, organic chemistry, and biophysics to explore the folding, assembly, and function of transmembrane channels and pores. These studies have led to the development of protein pores as "nanoreactors", with which both non-covalent and covalent chemistry of single molecules can be examined. Applications of this methodology have included host–guest interactions and step-by-step polymer growth. Based on this work, Bayley has developed "stochastic sensing," which has been shown with a wide variety of analytes to reveal both concentration and identity through single-molecule detection. In 2012, Bayley was elected as a Fellow of the Learned Society of Wales. The Science Council recognised him as "one of the UK's 100 leading practising scientists" of 2014.

Worked examples

Example 1 — a first encounter with Hagan Bayley

Start with the simplest possible case. Write down what Hagan Bayley 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 Hagan Bayley 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 Hagan Bayley 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 Hagan Bayley

In research: Hagan Bayley 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 Hagan Bayley 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: Hagan Bayley is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1951 births, Alumni of Balliol College, Oxford, British chemist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Hagan Bayley 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.
