Ahmad El-Hellani studies the chemistry and toxicology of electronic cigarettes and other nicotine delivery products, including how device design, liquid ingredients, and user behavior affect nicotine delivery and the formation of harmful chemicals like carbonyls. His work combines laboratory chemical analysis of vaping products with clinical studies of how nicotine enters the bloodstream, aiming to inform tobacco regulation and public health policy.
Publication output has grown over the past decade, rising from about 2-3 papers per year in 2017-2019 to a peak of around 9 papers in 2024, with sustained high activity through 2025.
