Reference excerpt

Vittoria Colizza is an Italian scientist, research director at INSERM and a specialist in mathematical modeling of infectious disease and computational epidemiology. In particular, she has carried out research on the modeling of seasonal and pandemic flu, Ebola and the COVID-19 pandemic.

Career Vittoria Colizza was born in 1978 in Rome, Italy. She earned her undergraduate degree in physics from the University of Rome Sapienza in Italy, in 2001 and her PhD in Statistical and Biological Physics from the International School for Advanced Studies, Italy in 2004. After that, she moved to the United States and conducted postdoctoral research at the University of Indiana in Bloomington from 2004 to 2006 under the direction of Alessandro Vespignani, through a grant from the European Research Council, before becoming a visiting assistant professor at the same institution from 2006 to 2007. In 2007, Colizza joined the ISI Foundation in Turin, Italy, starting a new lab after receiving the award of a Starting Independent Career Grant in Life Sciences by the European Research Council Ideas Program. Here, she conducted research on the 2009 Influenza A (H1N1) pandemic. In 2011, Colizza joined the INSERM (French National Institute for Health and Medical Research) in Paris, where she was promoted to Research Director in 2017. She currently leads the EPICx lab at INSERM and works on modeling the spread of emerging infectious diseases using statistical physics, computational sciences and mathematical epidemiology. Colizza has also been a visiting professor at Tokyo Institute of Technology since 2020.

Research Collizza is known for her research on infectious disease dynamics and public health, using data-driven mathematical and computational models. Her research focuses on how hosts' behavior such as contact, commuting, air travel, migration, etc) result in the spread of disease. (CITE ORCID) and applications of her work can be seen in epidemics in humans (e.g. 2009 Influenza A (H1N1) pandemic, Ebola virus epidemic, seasonal flu, COVID-19 pandemic) and in animals (bovine brucellosis and tuberculosis), raising awareness of infectious diseases, providing risk assessment analyses to enable preparedness, mitigation and control of such diseases. Colizza has played a large role in the COVID-19 pandemic research in 2020. Her research includes predicting trends in importations of the pandemic in France and in Europe and also quantifying undetected imported cases, and evaluating the impact of lockdown measures in France and the proposal of exit strategies. Colizza and her team have been also investigating the effect of school closure and testing in the mitigation of COVID-19.

Awards and honors 2021: Prix Irène Joliot Curie – Prix spécial de l'engagement by the French Academy of Sciences 2020: Knight of the Order of Merit of the Italian Republic 2012: Louis-Daniel Beauperthuy Prize from the Académie des Sciences 2013: Young Scientist Prize in Socio-Econophysics 2013, awarded by the German Physics Association. 2017: Erdős–Rényi prize for her contributions to fundamental and data-based modeling of network epidemic processes. 2017: Telethon-Farmindustria Award for her research predicting the peak of the Influenza A (H1N1) pandemic in 40 countries.

Worked examples

Example 1 — a first encounter with Vittoria Colizza

Start with the simplest possible case. Write down what Vittoria Colizza 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 Vittoria Colizza 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 Vittoria Colizza 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 Vittoria Colizza

In research: Vittoria Colizza 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 Vittoria Colizza 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: Vittoria Colizza is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1978 births, 21st-century Italian scientists, 21st-century Italian women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Vittoria Colizza 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.
