    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 currently serves on the Board of Scientific Counselors for the US Environmental Protection Agency's Chemical Safety for Sustainability/Human Health Risk Assessment Subcommittee. She has served as a technical expert to the Alliance for the Great Lakes and the International Joint Commission regarding the potential impacts of pharmaceuticals, personal care products and other emerging contaminants on the Great Lakes. She has also served as an invited scientific expert to both the US National Nanotechnology Initiative and the International Organization for Economic Cooperation and Development panel on nanotechnology where she has testified on the potential impact of nanoparticles on the environment and the utility of current testing strategies. She served on the National Academy of Sciences Panel to Develop a Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials. 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.

  • Sonya K. Sobrian, Ph.D.
    Associate Professor, Department of Pharmacology, Howard University College of Medicine Director, Developmental Neurobehavioral Pharmacology Laboratory Howard University, Washington, DC


    Ph.D., Physiological Psychology, Carleton University, Ottawa Canada

    Biographical Sketch

    Dr. Sonya K. Sobrian is an Associate Professor of Pharmacology at the Howard University College of Medicine, Director of the Developmental Neurobehavioral Pharmacology Laboratory, and Immediate Past Chair of the University's IACUC. Dr. Sobrian received her doctorate in Physiological Psychology from Carleton University, Ottawa Canada, and served a postdoctoral fellowship at Princeton University in Developmental Neurobiology; she also added pharmacology and immunology to her graduate (MA, Neuropharmacology: Ottawa University) and post graduate (Fulbright Fellow: Immunology Research Center, Belgrade, Yugoslavia) training.

    The major focus of Dr. Sobrian's research involves the behavioral, immunological, and neurotoxicological consequences of prenatal and neonatal drug administration and drug and environmental stress-induced alterations in behavioral and immunological development. She has a longstanding interest in sex differences, and her lab was the first to show that prenatal environmental and psychological stress deferentially altered immune parameters in rat male and female offspring, research that she continued as a Fulbright Scholar at the Immunological Research Institute in Belgrade, Yugoslavia. Her current research involves the life-span consequences of prenatal exposure to cocaine and nicotine, alone and in combination, with an emphasis on drug addiction in the aging organism. In developing animal models for neuropsychiatric diseases, Dr. Sobrian is currently exploring the role of prenatal environmental noise stress (PENS) in the etiology of autism and depression. For her work in establishing an environmentally-mediated neurodevelopmental animal model of depression, Dr. Sobrian was designated a L. Vernon Maddox NARSAD investigator.
