Margaret Daube-Witherspoon

Margaret Daube-Witherspoon is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Margaret Daube-Witherspoon rather than just read about it. In short: Margaret E. Daube-Witherspoon is an American biomedical engineer specializing in positron emission tomography.

Key takeaways

Margaret Daube-Witherspoon belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Margaret Daube-Witherspoon to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Margaret Daube-Witherspoon from memory before moving on to harder problems.

Reference excerpt

Margaret E. Daube-Witherspoon is an American biomedical engineer specializing in positron emission tomography. She holds the position of "senior research investigator extraordinaire" with the PennPET Explorer project in the Department of Radiology of the Perelman School of Medicine at the University of Pennsylvania.

Education and career Daube-Witherspoon majored in physics at Swarthmore College, graduating in 1978. She completed a Ph.D. in physics in 1983 at the University of Wisconsin–Madison. After postdoctoral research from 1983 to 1986 with Gerd Muehllehner at the University of Pennsylvania, she worked in the National Institutes of Health from 1986 until 1998, before returning to her present position at the University of Pennsylvania. She was president of the Physics, Instrumentation and Data Sciences Council of the Society of Nuclear Medicine and Molecular Imaging from 1995 to 1997.

Recognition Daube-Witherspoon was elected as an IEEE Fellow, in the 2023 class of fellows, "for contributions to 3D image reconstruction in PET and corrections for physics effects".

Worked examples

Example 1 — a first encounter with Margaret Daube-Witherspoon

Start with the simplest possible case. Write down what Margaret Daube-Witherspoon claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Margaret Daube-Witherspoon 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 Margaret Daube-Witherspoon 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 Margaret Daube-Witherspoon

In research: Margaret Daube-Witherspoon appears in engineering 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 Margaret Daube-Witherspoon 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: Margaret Daube-Witherspoon is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American engineers, 21st-century American women engineers, American biomedical engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Margaret Daube-Witherspoon 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.
