Overview


Dr. Di Giulio's research is concerned with basic studies of mechanisms of contaminant metabolism, adaptation and toxicity, and with the development of mechanistically-based indices of exposure and toxicity that can be employed in biomonitoring. The long term goals of this research are to bridge the gap between mechanistic toxicological research and the development of useful tools for environmental assessment, and to elucidate linkages between human and ecosystem health. The bulk of Dr. Di Giulio's work employs a comparative approach with aquatic animals, particularly fishes, as models. Of particular concern are mechanisms of oxidative metabolism of aromatic hydrocarbons, mechanisms of free radical production and antioxidant defense, and mechanisms of chemical carcinogenesis, developmental perturbations and adaptations to contaminated environments by fishes.

Evaluating the use of the extracellular flux analyzer assay to determine mitochondrial effects of pesticides with zebrafish (Danio rerio).

Journal article Comparative biochemistry and physiology. Toxicology & pharmacology : CBP · October 2026 Pesticides are used to control pest organisms and diseases in order to protect products and increase productivity. Improper use of these pesticides can lead to environmental accumulation in water, where they can become a risk to non-target organisms. Zebra ... Full text Cite

Developmental exposure to cigarette smoke particulate matter induces cross-generational DNA methylation changes in zebrafish.

Journal article Comparative biochemistry and physiology. Toxicology & pharmacology : CBP · July 2026 Prenatal exposure to cigarette smoke has been associated with adverse developmental outcomes and epigenetic alterations; however, the persistence of these effects across generations remains poorly understood. Using zebrafish (Danio rerio), we investigated ... Full text Cite

How can academic researchers more effectively contribute to environmental toxicology and health efforts for regulatory decisions, policymakers, nonprofits, and communities?

Journal article Journal of toxicology and environmental health. Part B, Critical reviews · January 2026 Most ecological and human environmental health researchers are motivated both by curiosity and a desire to do work that will be useful sooner rather than later. However, the academic research process does not always produce and present results that meet th ... Full text Cite
