Sabina Halappanavar

Sabina Halappanavar is an Adjunct Professor in the Department of Biology at the University of Ottawa's Faculty of Science. Her work focuses on molecular toxicology, genomics, nanomaterials, and cardiopulmonary effects. She specializes in validating high-content molecular tools for assessing environmental chemical risks, including engineered nanomaterials.

Her research interests include understanding gene expression changes caused by environmental exposures, such as air pollution and nanoparticles, and their implications for human health. Key projects involve investigating pulmonary and hepatic responses to nanomaterials, forestomach carcinogenesis from benzo(a)pyrene, and microRNA regulation in inflammatory conditions.

Dr. Halappanavar's recent publications (2013) explore topics like titanium dioxide nanoparticle toxicity, urban air pollution effects on lipid pathways, and maternal nanomaterial exposure impacts. While no specific grants or awards are listed, her work emphasizes translational research bridging molecular biology and regulatory oversight in toxicology.
