Dr. De Vizcaya-Ruiz is an award-winning expert in environmental toxicology whose research focuses on the effects of particulate matter, microplastics, and nanomaterials toxicity on the human body. Using in vitro and in vivo models, she assesses different physiological responses – from issue injury and inflammation to oxidative stress – that arise after exposure to different environmental and occupational hazards. She has over 50 peer-reviewed publications, in addition to 10 book chapters and short reviews on toxicology. De Vizcaya-Ruiz also has active interdisciplinary collaborations with other research groups in Mexico, the Netherlands, Canada, and across the U.S.
In addition to her role as Professor, De Vizcaya-Ruiz also participates in several research initiatives across the university. These include the Center for Occupational and Environmental Health (COEH), Air Pollution Health Effects Lab (APHEL), and UCI Atmospheric Integrated Research unit (AirUCI). Outside of her various roles at UCI, she has also participated as an advisor for the Mexican Ministry of Health, the Mexican Ministry of Environment and the Mexico City Government to help establish guidelines on air pollution and regulation of nanomaterials safety. She also serves as a member of the Editorial Board of Particle and Fibre Toxicology and as an active member of the US Society of Toxicology and the Mexican Society of Toxicology.
“Health equity has always been an important component of my work. In toxicology, we always think about how exposures will affect different groups. When we design a study, we must consider what happens to different populations."
I was always interested in the natural sciences and biology. Anything that had to do with living things, really. After majoring in veterinary medicine as an undergraduate student at the National Autonomous University of Mexico, I soon discovered toxicology, specifically how experimental in vitro (cellular) and in vivo (animal) models are used to understand health effects in human populations. It wouldn’t take long for me to realize that this was my passion.
