# Lone Simonsen

Lone Simonsen (born 1959) is a Danish epidemiologist and professor of population health sciences. Since the beginning of 2020, she has been the director of PandemiX, an interdisciplinary pandemic research center at Roskilde University. In 2023 PandemiX was established as a Center of Excellence funded by the Danish National Research Foundation.
After receiving her graduate degree in biology and chemistry from Roskilde University in 1985, Simonsen continued her educational career at University of Massachusetts Amherst and in 1992 she received her PhD degree in population genetics. After receiving her degree at UMass, Simonsen conducted research in microbial ecology as a postdoctoral fellow at Danish Technical University. In 1992, she started working as a epidemiologist at Centers for Disease Control and Prevention, where in 1994, she received her graduate diploma in applied epidemiology.
Simonsen continued her career as a epidemiologist working for WHO, UNAIDS and later at NIH, where she conducted research in influenza pandemics. During her career, Simonsen has worked with issues including HIV/AIDS, tuberculosis, antibiotic resistance, SARS, pandemic influenza, e-health, surveillance systems and vaccine program evaluation. She was assigned by the NIH to WHO in Geneva to work on the SARS outbreak in 2003. She uses historical and current disease data together with mathematical models to predict the development of current and future epidemics. Trained in population genetics and epidemiology in the US, Simonsen returned to her native Denmark in 2014, working first at University of Copenhagen and later at University of Roskilde.

## COVID-19

During the COVID-19 pandemic, Simonsen has been a central scientist advising the Danish health authorities and the government on the evolving situation, as well as conducted groundbreaking research on superspreading. She was often used as an epidemiological expert by Danish media and her large exposure gave her the nickname "Corona-Lone".

## Publications

Her primary research field is epidemiology and pandemics. Her main work are within these fields, but her publications cover a broad spectrum of themes within historical epidemiology, burden of disease modelling, global health epidemiology, vaccine program evaluation together with interdisciplinary research.
