Miriam Aguilar-Lopez, MSc

Miriam completed her undergraduate studies in Nutrition at the State University of Hidalgo (UAEH) in Mexico.  In 2012, she began a 1-year internship in the National Institute of Medical Sciences and Nutrition “Salvador Zubiran” in Mexico City. She was part of a study assessing the prevalence of different single nucleotide polymorphisms associated with obesity and diabetes in the Mexican population. In 2015, she completed her MSc in Health Sciences with a focus in Clinical Epidemiology at the National University of Mexico (UNAM). Her research project focused on a dietary intervention with functional foods to improve biomarkers related to metabolic syndrome. At this time, she started to explore the gut microbiome and its effects on health. In 2015, she was a visiting scholar at the University of Illinois Urbana-Champaign under the supervision of Dr. Sharon Donovan. She was fascinated by the gut microbiome and all its significant associations with human health, particularly in the pediatric population, that she decided to continue learning and studying the effect of nutrition on the gut microbiome. Currently, Miriam is a Ph.D. candidate in Nutritional Sciences at the University of Illinois Urbana-Champaign in Dr. Donovan’s Lab. Her current research seeks to understand the effects of human milk and milk fortifiers on the development of the gut microbiome of premature infants and how the gut microbiome might associate with the infant’s growth and development. She has been a member of the ISRHML since 2018. Miriam is currently the ISRHML Trainee Representative of the Region of the Americans. She is happy and excited to be involved in this society and organize the webinars for this region. As part of this role, she hopes to increase the involvement of more researchers and participants from Latin America in these webinars and in the ISRHML society.
