Reference excerpt

Kathleen "Kathy" Lewis is an environmental chemist and professor of agricultural chemistry at University of Hertfordshire known for her work on environmental management, especially in the realm of pollution from chemicals.

Education and career Lewis earned a Ph.D. from the University of Hertfordshire in 1999. She was awarded the title of Professor in 2014 and, as of 2022, she is a professor at the University of Hertfordshire.

Academic work Lewis is known for her research in agriculture, especially on the evaluation and management of the environmental impact of agriculture. Her early work developed metrics to quantify the impact of agriculture and pesticides on the environment, and applied these tools to agricultural activities in the United Kingdom. She developed a tool to track agricultural issues known as Environmental Management for Agriculture (EMA), which was distributed on CDs and has been retired. Her subsequent work is as the scientific lead for the on-line Pesticide Properties Database (PPDB). The PPDB provides chemical and environmental information on pesticides and, as of 2011, holds data on over 1800 chemical compounds. In a 2017 expansion of the database, Lewis provided a means to track how pesticides dissipate in the environment.

Worked examples

Example 1 — a first encounter with Kathleen Lewis (chemist)

Start with the simplest possible case. Write down what Kathleen Lewis (chemist) 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 Kathleen Lewis (chemist) 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 Kathleen Lewis (chemist) 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 Kathleen Lewis (chemist)

In research: Kathleen Lewis (chemist) 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 Kathleen Lewis (chemist) 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: Kathleen Lewis (chemist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academics of the University of Hertfordshire, Agricultural chemists, Alumni of the University of Hertfordshire, so understanding it makes those chapters shorter.
In everyday life: Look for Kathleen Lewis (chemist) 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.
