Reference excerpt

Varinder Kumar Aggarwal (born 1961) is an Indian organic chemist specialising in asymmetric synthesis. He is a Professor of Synthetic Chemistry at the School of Chemistry of the University of Bristol.

Early life Aggarwal was born in 1961 in Kalianpur, a town in Northern India. In 1963 his family emigrated to the United Kingdom. He was one of six sons, and grew up in Scotland, then Nottingham, England.

Education and career Aggarwal earned his PhD from the University of Cambridge in 1986 under the supervision of Stuart Warren. His thesis was entitled Stereocontrolled synthesis with phenylthio migration. He carried out postdoctoral work with Gilbert Stork at Columbia University, before taking up appointments first in Bath, then Sheffield and finally at the University of Bristol where he is currently a professor.

Research Aggarwal developed new methods of using chemical reactions to assemble complex, biologically important molecules. His research includes new ways of speeding up, or catalysing, these processes of synthesis. His work has applications in medicine, such as helping to provide a more effective vaccine against tuberculosis. Although many organic molecules can occur in "right-handed" and "left-handed" forms, invariably just one of these is seen in living organisms. Normal chemical reactions, however, make both forms in equal amounts. Aggarwal's work on asymmetric synthesis made it possible to selectively synthesise more of the form important to understanding biological processes. Aggarwal specialises in a type of molecule called ylides, which are important to the Wittig reaction – a standard tool in organic chemistry.

Awards and honours Aggarwal is the winner of multiple awards, including the Corday-Morgan and Organic Stereochemistry awards of the Royal Society of Chemistry. He was elected a Fellow of the Royal Society (FRS) in 2012. His certificate of election reads: Aggarwal is distinguished for his outstanding contributions to the field of asymmetric synthesis, particularly applications of ylide chemistry where he is the world leader. The important new methodology he has developed has been complemented by detailed mechanistic studies which have brought about improved understanding of many fundamental reactions. His innovative approach is highlighted by the unusual but highly effective reactions of sulphur ylides with boranes, an area that has much scope for future development. His productivity and breadth make him one of the foremost organic chemists of his generation and one who is very widely recognised internationally. 2019: Awarded the Davy Medal of the Royal Society. 2025: Awarded the Royal Society of Chemistry Pedler Prize.

Worked examples

Example 1 — a first encounter with Varinder Aggarwal

Start with the simplest possible case. Write down what Varinder Aggarwal 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 Varinder Aggarwal 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 Varinder Aggarwal 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 Varinder Aggarwal

In research: Varinder Aggarwal 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 Varinder Aggarwal 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: Varinder Aggarwal is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, 21st-century British chemists, Alumni of the University of Cambridge, so understanding it makes those chapters shorter.
In everyday life: Look for Varinder Aggarwal 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.
