MPH, University of Turin Andrea Baccarelli is an Italian American epigeneticist and clinical endocrinologist, best known for his academic contributions in the field of epigenetics, mitochondriomics, and computational epigenomics, with a research focus on investigating the impact of environmental exposures on human health.

[8] Baccarelli's research has pioneered the field of public health epigenetics, which explores how environmental factors can modify gene expression without changing the DNA sequence.

[9] His studies have demonstrated that air pollution can alter the epigenome, leading to changes in gene regulation that may contribute to the development of diseases such as cardiovascular disorders and neurodegenerative conditions.

[10][11] Baccarelli conducted research showing that short-term exposure to air pollution, including levels considered "acceptable," can impair cognitive ability in the elderly.

[15] He also conducted research showing that ambient air pollution is associated with an increased risk of osteoporosis and bone fractures in older individuals.
