Reference excerpt

Michael Joseph Ryan (born 1965) is an Irish epidemiologist and former trauma surgeon, specialising in infectious disease and public health. He is executive director of the World Health Organization's Health Emergencies Programme, leading the team responsible for the international containment and treatment of COVID-19. Ryan has held leadership positions and has worked on various outbreak response teams in the field to eradicate the spread of diseases including bacillary dysentery, cholera, Crimean–Congo hemorrhagic fever, Ebola, Marburg virus disease, measles, meningitis, relapsing fever, Rift Valley fever, SARS, and Shigellosis.

Early life and education Mike Ryan was born in London to Irish parents, moving to Mayo as a two-year-old. He grew up in the town of Charlestown in County Mayo. His father worked as a merchant sailor. Ryan trained in medicine at the National University of Ireland in Galway. He received training in orthopaedics in Scotland. Ryan has a Masters of Public Health (1992) from University College Dublin. He later completed specialist training in communicable disease control, public health and infectious disease at the Health Protection Agency in London. Ryan also completed the European Programme for Intervention Epidemiology Training (EPIET). In 2021, Ryan was awarded UCD Alumnus of the Year in Health and Agriculture Sciences.

Career

Early career In July 1990, Ryan moved to Iraq with his girlfriend, later his wife, to train Iraqi doctors. Very shortly after his arrival the Invasion of Kuwait happened, which suspended his work and meant he and his wife were made to work as doctors under captivity, often working under duress. A military convoy ran a vehicle Ryan was in off the road, crushing multiple vertebrae. Eventually Ryan and his wife were allowed to leave Iraq due to their injuries. Ryan's severe back injury prohibited him from working as a surgeon. He made a shift into the fields of public health and infectious disease. Ryan worked with the Bill & Melinda Gates Foundation on their efforts to eradicate infectious diseases in Africa.

Worked examples

Example 1 — a first encounter with Michael J. Ryan (doctor)

Start with the simplest possible case. Write down what Michael J. Ryan (doctor) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Michael J. Ryan (doctor) 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 Michael J. Ryan (doctor) 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 Michael J. Ryan (doctor)

In research: Michael J. Ryan (doctor) appears in astronomy 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 Michael J. Ryan (doctor) 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: Michael J. Ryan (doctor) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1965 births, 20th-century Irish medical doctors, 20th-century Irish surgeons, so understanding it makes those chapters shorter.
In everyday life: Look for Michael J. Ryan (doctor) 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.
