Currently, his research focuses on the physiological and endocrine mechanisms in mothers during gestation, as well as the role of the placenta in women's health after pregnancy. His studies are framed within the DOHaD theory (Developmental Origins of Health and Disease), which suggests that environmental factors during gestation and infancy can have long-term consequences on the health of the offspring.
