Rate My Professor Alan Vajda

Alan Vajda, Ph.D., serves as a Professor and Biology Research Faculty member in the Department of Integrative Biology at the University of Colorado Denver's College of Liberal Arts and Sciences. He earned his Ph.D. in Environmental Endocrinology and M.A. in Environmental Toxicology from the University of Colorado at Boulder, along with a B.A. in Biology and Science, Technology, and Society from Pomona College in California. In his role as a graduate advisor, Vajda instructs courses such as Human Physiology (BIOL 3225), Environmental Toxicology (BIOL 4460/5460), Endocrinology (BIOL 4674/5674), and Topics in Integrative and Systems Biology (BIOL 7010).

The research in Vajda's laboratory centers on the emerging eco-human health concerns posed by endocrine-active chemicals in the environment. Investigations include neural mechanisms underlying reproductive disruption from estrogenic mixtures, ecosystem responses to wastewater treatment plant upgrades, and the effects of water management decisions on mitigating chemical impacts to human and wildlife health. His expertise encompasses endocrine disruption, environmental toxicology, and ecological developmental biology. Key publications feature 'Reproductive disruption in fish downstream from an estrogenic wastewater effluent' (Environmental Science & Technology, 2008), which revealed intersex conditions and reproductive impairments in Colorado streams affected by wastewater; 'Demasculinization of male fish by wastewater treatment plant effluent' (Aquatic Toxicology, 2011); 'Fish endocrine disruption responses to a major wastewater treatment facility upgrade' (Environmental Science & Technology, 2012); 'Perturbation and restoration of the fathead minnow gut microbiome after low-level triclosan exposure' (Microbiome, 2015); 'Integrated assessment of wastewater treatment plant effluent estrogenicity in the Upper Murray River, Australia, using the native Murray rainbowfish (Melanotaenia fluviatilis)' (Environmental Toxicology and Chemistry, 2015); 'Multi-omic responses of fish exposed to complex chemical mixtures in the Shenandoah River watershed' (Science of the Total Environment, 2023); and 'Bioconcentration of Per- and Polyfluoroalkyl Substances and Precursors in Fathead Minnow Tissues Environmentally Exposed to Aqueous Film-Forming Foam-Contaminated Waters' (Environmental Toxicology and Chemistry, 2024). Vajda's contributions have illuminated contaminant effects on aquatic life and supported environmental policy and management.
