About Jon Allem, PhD, MA

Jon-Patrick Allem is an Assistant Professor of Research at the Keck School of Medicine of USC. Dr. Allem's research harnesses digital data sources and cutting-edge methodologies to improve population health surveillance and policy. His multidisciplinary expertise in behavioral science, preventive medicine, and data science has led to data-driven public health insights featured in prominent media and scholarly outlets such as Nature, Scientific American, CNN, and the American Journal of Public Health. With the use of data from online platforms such as Twitter, Instagram, YouTube, and Google Web Search, Dr. Allem's research has included studies on the effectiveness of mass media campaigns, use and appeal of tobacco products, HIV education, the marketing practices of micromobility companies, and the sources and content of online misinformation. He has successfully competed for close to 4 million dollars in government contracts and grants, with current projects focused on identifying sources of exposure to tobacco marketing among adolescents and young adults. He recently became the principal investigator for the California Tobacco Control Program's Tobacco Industry Monitoring Evaluation. The main goal of the project is to inform comprehensive tobacco control policy efforts by monitoring core tobacco industry practices related to electronic cigarettes and other new and emerging non-combustible nicotine products, and little cigars and cigarillos in three core tobacco industry practices: advertising and marketing on social media platforms, direct marketing, and underage online sales.
