Reference excerpt

Rebecca J. Troisi is an American cancer epidemiologist specialized in the hormonal etiologies of reproductive cancers. She was a senior associate scientist in the trans-divisional research program at the National Cancer Institute before retiring in 2026.

Life Troisi completed a Sc.D. from the Harvard T.H. Chan School of Public Health in 1994. Her dissertation was titled, Epidemiology of adult-onset asthma. She joined the National Cancer Institute (NCI) the same year. Her research has focused on the hormonal etiologies of reproductive cancers and the role of maternal, gestational, neonatal and early life factors in breast cancer risk, including endocrine disruptors such as diethylstilbestrol, a drug previously given to pregnant women. Troisi and colleagues Marlene Goldman and Kathryn Rexrode edited the second edition of Women and Health, a comprehensive review of the behavioral, social, and biological determinants of health and well-being in women, published in late 2012 and the third edition published in 2026 by Elsevier. Troisi was a senior associate scientist in the trans-divisional research program in the NCI division of cancer epidemiology and genetics before retiring in 2026.

Worked examples

Example 1 — a first encounter with Rebecca J. Troisi

Start with the simplest possible case. Write down what Rebecca J. Troisi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Rebecca J. Troisi 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 Rebecca J. Troisi 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 Rebecca J. Troisi

In research: Rebecca J. Troisi appears in science 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 Rebecca J. Troisi 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: Rebecca J. Troisi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American women scientists, American epidemiologists, American women epidemiologists, so understanding it makes those chapters shorter.
In everyday life: Look for Rebecca J. Troisi 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.
