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.
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. [1] [2]
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. [3]
Colizza has also been a visiting professor at Tokyo Institute of Technology since 2020.
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. [4]
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. [5] [6] Colizza and her team have been also investigating the effect of school closure and testing in the mitigation of COVID-19. [7] [8]
Vittoria Colizza has published or co-published more than a hundred scientific articles at the end of 2020, including:
A pandemic is an epidemic of an infectious disease that has a sudden increase in cases and spreads across a large region, for instance multiple continents or worldwide, affecting a substantial number of individuals. Widespread endemic diseases with a stable number of infected individuals such as recurrences of seasonal influenza are generally excluded as they occur simultaneously in large regions of the globe rather than being spread worldwide.
The 1918–1920 flu pandemic, also known as the Great Influenza epidemic or by the common misnomer Spanish flu, was an exceptionally deadly global influenza pandemic caused by the H1N1 subtype of the influenza A virus. The earliest documented case was March 1918 in the state of Kansas in the United States, with further cases recorded in France, Germany and the United Kingdom in April. Two years later, nearly a third of the global population, or an estimated 500 million people, had been infected in four successive waves. Estimates of deaths range from 17 million to 50 million, and possibly as high as 100 million, making it one of the deadliest pandemics in history.
An influenza pandemic is an epidemic of an influenza virus that spreads across a large region and infects a large proportion of the population. There have been six major influenza epidemics in the last 140 years, with the 1918 flu pandemic being the most severe; this is estimated to have been responsible for the deaths of 50–100 million people. The 2009 swine flu pandemic resulted in under 300,000 deaths and is considered relatively mild. These pandemics occur irregularly.
Alessandro Vespignani is an Italian-American physicist, best known for his work on complex networks, and particularly for work on the applications of network theory to the mathematical modeling of infectious disease, applications of computational epidemiology, and for studies of the topological properties of the Internet. He is currently the Sternberg Family Distinguished University Professor of Physics, Computer Science and Health Sciences at Northeastern University, where he is the director of the Network Science Institute.
The 2009 swine flu pandemic, caused by the H1N1/swine flu/influenza virus and declared by the World Health Organization (WHO) from June 2009 to August 2010, was the third recent flu pandemic involving the H1N1 virus. The first identified human case was in La Gloria, Mexico, a rural town in Veracruz. The virus appeared to be a new strain of H1N1 that resulted from a previous triple reassortment of bird, swine, and human flu viruses which further combined with a Eurasian pig flu virus, leading to the term "swine flu".
In public health, social distancing, also called physical distancing, is a set of non-pharmaceutical interventions or measures intended to prevent the spread of a contagious disease by maintaining a physical distance between people and reducing the number of times people come into close contact with each other. It usually involves keeping a certain distance from others and avoiding gathering together in large groups.
The pandemic H1N1/09 virus is a swine origin influenza A virus subtype H1N1 strain that was responsible for the 2009 swine flu pandemic. This strain is often called swine flu by the public media due to the prevailing belief that it originated in pigs. The virus is believed to have originated around September 2008 in central Mexico.
The 1889–1890 pandemic, often referred to as the "Asiatic flu" or "Russian flu", was a worldwide respiratory viral pandemic. It was the last great pandemic of the 19th century, and is among the deadliest pandemics in history. The pandemic killed about 1 million people out of a world population of about 1.5 billion. The most reported effects of the pandemic took place from October 1889 to December 1890, with recurrences in March to June 1891, November 1891 to June 1892, the northern winter of 1893–1894, and early 1895.

Individual human mobility is the study that describes how individual humans move within a network or system. The concept has been studied in a number of fields originating in the study of demographics. Understanding human mobility has many applications in diverse areas, including spread of diseases, mobile viruses, city planning, traffic engineering, financial market forecasting, and nowcasting of economic well-being.
The International School and Conference on Network Science, also called NetSci, is an annual conference focusing on networks. It is organized yearly since 2006 by the Network Science Society. Physicists are especially prominently represented among the participants, though people from other backgrounds attend as well. The study of networks expanded at the end of the twentieth century, with increasing citation of some seminal papers.
