Profile Headshot


Manuela Orjuela-Grimm  is a molecular epidemiologist and pediatric oncologist whose research focuses on vulnerability (including social) to environmental exposures, gene-nutrient/ environment interactions during windows of susceptibility such as pregnancy, early childhood, adolescence and the development of later genetic and epigenetic changes contributing to poorer health outcomes in childhood and adolescence. She leads EpiRbMx, a long standing case control/ case series study examining exposure to methyl donors, folate pathway metabolism and risk for retinoblastoma in collaboration with a multidisciplinary team of investigators including the Hospital Infantil de Mexico, the Hospital de Pediatria at the Instituto Mexicano de Seguro Social (IMSS), the Instituto Nacional de Salud Publica (INSP),  and the University of Toronto. In collaboration with INSP researchers, Dr Orjuela is involved in multiple studies examining the intersection between food security, folate related dietary intake, dietary diversity and environmental exposures in central Mexico, including in migrants in transit through Mexico, and in recent Mexican immigrants in New York.

Interests: social contributors to dietary exposures, gene-nutrient interactions; one carbon donor metabolism; methylation; nutrient and environmental exposures during early life and later genetic and epigenetic effects; dietary assessment in Mexico, in populations in 'active migration', and in migrants from Latin America; effects of acculturation and early life migration on nutrient/ environmental exposures in US Latinos.

Global Health Activities

EpiRbMx, Mexico: Epidemiology of sporadic Retinoblastoma in Mexico, Mexico: This project examines the role that gene- nutrient interactions play in the development of retinoblastoma and RB1 genetic and epigenetic changes. We examine the effect of early life exposure to dietary intake of folate/folic acid, genetic variation in metabolism of folate and genetic and epigenetic changes in RB1 and in the development of sporadic retinoblastoma in central Mexico. A collaboration with the Hospital Infantil de Mexico, the Nutrition Epidemiology group of the Instituto Nacional de Salud Publica, the Hospital de Pediatria Siglo XXI of the Instituto Mexicano de Seguro Social (IMSS), and the Instituto de Fisiologia Celular of the Universidad Nacional Autonoma de Mexico(UNAM).

Prenatal Exposures and Procarcinogenic Mutations: This project evaluates pre-natal environmental exposures that may increase the risk of childhood ALL. We propose to measure chromosomal aberrations a subset of newborns from the Columbia Center for Children's Environmental Health (CCCEH) Prospective Cohort Study to gain a greater understanding of the mechanism underlying the development of the first hit in ALL, and to identify exposures that may be causally associated with the development of intermediate genetic changes. A collaboration with the CCCEH and the Institute for Cancer Research, Surrey, UK

METIAB (Measurement of Food Security and Wellbeing in Migrants in Transit), Mexico, Costa Rica: METIAB is a multidisciplinary multisectorial cooperation that seeks to develop informative measurement tools to assess the severity and magnitude of food insecurity in migrants in transit through Mexico. The group includes members from the Instituto Nacional de Salud Publica (Mexico), the Colegio de la Frontera Norte (Mexico), the UN Institutes of Migration (Latin American Regional Office in San Jose, Costa Rica; Mexico Office), the UN Food and Agriculture Organization, and the Casa del Migrante, Saltillo (Mexico). METIAB has received funding from the Institute for Latin American Studies (ILAS)

Urban Health Activities

COMIDITA (Cognitive Outcomes Mexican Immigrants Dietary Intake Toddler Assessment): COMIDITA examines the relationship between toddler nutrition and neurocognitive outcomes in children of recent Mexican immigrants. We are examining the relationship between specific micronutrients and children's performance in neurocognitive assessments. The project involves the Department of Pediatrics, with advising from Fabiola Mejia-Rodriguez at the INSP in Mexico, and Ligi Paul at Tufts University. We have received R21 funding from NIH (NIMHD) as well as pilot funding the Institute of Latin American Studies, and a planning grant (CaMPR) from the CTSA.

Migration and Diet in migrant Mexican women : The Evaluation of Comprando Rico y Sano (CRyS) uses a CBPR based approach, funded by the Community Engagement Resource (CECR) of the Columbia CTSA. We are working in partnership with our community partner the Mexican Coalition, to evaluate the dietary impact of participation in workshops following the UnidosUS/National Council of La Raza curriculum designed to improve healthy grocery purchasing. Our joint project works with community health workers and focuses on Mexican immigrants in the South Bronx and Northern Manhattan.

CAMINANDO: CAMINANDO examines diet, living conditions and risk and protective factors for post migration health in adolescent migrants from Latin America settling in New York. Our multidisciplinary team works with local community partners offering services to migrant teens. We also collaborate with the Instituto Nacional de Salud Publica in Mexico's work on nutrition in young migrants in Mexico. We have received pilot funding from the Columbia Global Mental Health Pilot program, Columbia Population Research Council, and the Institute for Latin American Studies.
