Dr. Klaper received her MS in Entomology in 1995 and her Ph.D. in Ecology in 2000 from the Institute of Ecology University of Georgia examining the impacts of chemicals on the population dynamics of insects.
Dr. Klaper currently studies the potential impact of emerging contaminants, such as nanoparticles, pharmaceuticals, personal care products and pesticides on aquatic life and how we may design these chemicals to be sustainable and have the least environmental impact. She published some of the first studies on the impacts of nanomaterials on aquatic organisms, describing differences in toxicity among nanomaterials, discussing the possible impacts of surfactants on nanomaterial toxicology. Dr. Klaper is now one of the lead PI's for the Center for Sustainable Nanotechnology, a distributed Center of eight universities to evaluate the mechanisms by which nanomaterials may cause toxicity and investigate the potential for principles to use in the design process of these chemicals.
Dr. Klaper received a AAAS-Science and Technology Policy Fellowship where she worked in the National Center for Environmental Assessment at the US Environmental Protection Agency evaluating the potential use of genomic technologies in risk assessment. She is also on the editorial board of the SETAC journal Environmental Toxicology and Chemistry as well as the ACS journal Chemical Research in Toxicology. Her current research focuses on (1) determining the presence of contaminants in freshwater systems; (2) the impacts of low level chronic exposures of these chemicals to fish and invertebrates in freshwater systems; (3) evaluating the ability of contaminant removal technologies to remove biological impacts of chemicals; (4) methods to quickly assess the potential impacts of a chemical, including genomic technologies; and (5) alternative options for minimizing the impacts of emerging contaminants including chemical redesign and Green Chemistry, altering use and distribution, and evaluating prescription levels for pharmaceuticals. Dr. Klaper's goal is to conduct basic and applied research to inform policy decisions involving freshwater resources.
