Alejandra Rojas did her degree in Biology in Universidad Nacional de Colombia. Later, during her master's degree in Brazil (Universidade Federal do Rio Grande do Sul), her dissertation was about genetic variations, DNA methylation and perinatal outcomes in new-borns with prenatal exposure to crack and cocaine in Rio Grande do Sul. Her current research topic is the interactions between maternal genes and nutrients, the development of pregnancy and development in the offspring. She is specifically interested in the effects of the level of maternal folate and other related metabolites on metabolic markers of childhood, as well as its effect on epigenetic regulation.

Project: Interactions between genes and maternal nutrients and development in the infant

Maternal imbalances in one carbon metabolites (folates, cobalamin, choline, betaine, dimethylglycine, methionine, and homocysteine), may be associated with epigenetic biomarkers and metabolic outcomes in children at 6-8 years of age. Considering this, the global aim is to investigate transgenerational association between maternal one carbon metabolism, and health and developmental outcomes in the child.
