Willem Gijsbert "Wilbert" Van Panhuis 

Willem G. “Wilbert” Van Panhuis, MD, PhD, died April 13 after a two-year battle with glioblastoma, a brain cancer, at age 48. He held appointments as associate professor of epidemiology at the University of Pittsburgh School of Public Health and biomedical informatics in the School of Medicine. He left Pitt in 2001 to become director of the Office of Data Science and Emerging Technologies at the National Institute of Allergy and Infectious Diseases (NIAID).

Born in the Netherlands, he completed his medical degree at the free Medical University in Amsterdam before coming to the United States and earning a doctorate in global disease epidemiology at the Johns Hopkins Bloomberg School of Public Health in 2009. He joined the Pitt faculty that same year, where he quickly emerged as a leader in population health informatics, data sharing, data visualization, computational epidemiology and infectious disease surveillance on a global level. He taught courses and mentored graduate students on the epidemiology of infectious diseases and vaccines. 

Van Panhuis was expert at assembling and analyzing large infectious disease epidemiology data sets, and in discovering multidecadal, continental scale patterns. He led Project Tycho, a heroic effort that digitized the history of infectious diseases in the U.S. for all cities and states from 1888 onward and used creative analytic and visualization methods to demonstrate that childhood vaccination prevented 100 million cases of serious childhood diseases. He also led a large multi-country collaboration on dengue that revealed region-wide synchrony and traveling waves of dengue across eight countries in Southeast Asia. A champion of open access to data, he led an international team that systematically identified technical, motivational, economic, political, legal and ethical barriers to public health data sharing.

In 2019, he became principal investigator of the Network Coordination Center for the NIH Models of Infectious Disease Agent Study (MIDAS), a nationwide collaborative research network of infectious disease epidemiologists, data scientists and computational modelers.
Van Panhuis served as director of the Office of Data Science and Emerging Technologies from 2021 through 2024, where he played a key role in advancing NIAID's data management and sharing strategy. He took a medical retirement in 2004. Van Panhuis’ expertise and leadership have had a profound impact on improving access and use of data for public health research globally.
