Reference excerpt

Patrick G. O’Shea (born c. 1957) is an Irish-American scientist and academic. From February 2017 to September 2020, he was the fifteenth president of University College Cork. He was previously vice president and chief research officer at the University of Maryland.

Biography O'Shea was born in Cork, Ireland, and attended secondary school at Coláiste Chríost Rí. He has a B.Sc. degree from University College Cork, and M.S. and Ph.D. degrees from the University of Maryland, all in physics. At Maryland, O'Shea was a professor in the Department of Electrical and Computer Engineering and an affiliate professor in the Department of Physics, and was previously chair of the Department of Electrical and Computer Engineering and director of the Institute for Research in Electronics and Applied Physics. O'Shea's area of expertise is in electromagnetics, electron-accelerators and free-electron lasers. He is a Fellow of the American Physical Society, the Institute of Electrical and Electronics Engineers and the American Association for the Advancement of Science. He is also a University of Maryland Distinguished Scholar-Teacher. His board memberships include the Universitas 21 Research Leaders Steering Group, the National Institute of Aerospace, Oak Ridge Associated Universities, Maryland Life Sciences Advisory Board, the Maryland Cybersecurity Council and the Maryland Innovation Initiative. On 14 June 2016, O'Shea was appointed the fifteenth president of University College Cork, effective from 1 February 2017. On 15 September 2020, O'Shea's retirement, announced in July 2020 began. In March 2025, it was announced that O'Shea was assuming the position of Deputy Vice President for Research at the University of Maryland. O'Shea and his wife, Miriam, were married in 1987. They have a son, Ronan.

Worked examples

Example 1 — a first encounter with Patrick G. O'Shea

Start with the simplest possible case. Write down what Patrick G. O'Shea claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Patrick G. O'Shea 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 Patrick G. O'Shea 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 Patrick G. O'Shea

In research: Patrick G. O'Shea appears in physics 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 Patrick G. O'Shea 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: Patrick G. O'Shea is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950s births, 20th-century Irish physicists, 21st-century Irish physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Patrick G. O'Shea 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.
