After completing her medical degree at Javeriana University School of Medicine (Bogota, Colombia) in 2007, she participated in the development and implementation of a surveillance program of birth defects, started a DNA bank with samples from infants with congenital defects, and developed a training program for medical staff to screen for birth defects.
During her postdoctoral fellowship and Master’s degree, her research in basic nutritional sciences focused on identifying factors associated with pregnancies complicated by birth defects, specifically midline field defects. She developed a laboratory assay to measure antibodies targeting folate receptors. The assay was effective to measure antibodies in a diversity of tissue samples (plasma, serum, placenta) in pregnancies complicated with neural tube defects, congenital heart defects and orofacial clefts. She also discovered a novel mechanism of teratogenicity of valproic acid, a common anti-epileptic drug used to treat epilepsy and bipolar disorders worldwide which is known to cause a variety of birth defects.
She then pursued a PhD in Nutritional Sciences at the University of Texas at Austin and graduated in 2020. During her studies, she did secondary analyses to identify factors associated with anemia in young children from Guatemala and Haiti. Her research to date has focused on identifying nutrition disparities and developing, implementing, and evaluating nutrition interventions (including some with micronutrient supplements) in Latin America and the US.
More recently, she has assessed barriers and facilitators to replacing packed snacks for fresh fruits and vegetables in childcare programs in urban and rural Georgia, and implemented two online randomized controlled trials, the first assessing the effectiveness of lactation cookies in objective and subjective measures of milk production; and the second trial assesses the effectiveness of an online digital wellness intervention in diet quality, weight loss and other secondary outcomes of overweight and obese US adults, relative to standard of care.
With her diverse background in medical and nutrition and implementation sciences, she has supported primary and secondary population-based nutrition and health studies and health studies across six different countries in Latin America and the US in a diversity of settings.
