The Environmental Health Sciences Center supports faculty members with strong interests in environmental hgealth science reserarch and outreach.  The Career Development Core helps faculty develop strong programs and build effective networks to become leaders in the environmental health field.  The core will enable and energize new faculty to coalesce into teams that will develop novel approaches to address the strategic goals of NIEHS.

The Core has a network of Center members and other experts across the OSU campus to serve as mentors and potential collaborators.  Our professional networks also include other Environmental Health Sciences Centers and NIEHS funded groups.

Research efforts of new investigators can be supported by the Career Development Core.  There are also pilot project opportunities.

Graduate and Postdoctoral Training Program Overview

EHSC faculty, staff, and core units assist in the recruitment and training of promising individuals to levels in toxicology and environmental health that can effectively meet the growing global challenge.

The Training Programs, with their hands-on interdisciplinary research opportunities and complementary academics, are integral to providing vital graduate and postdoctoral training at OSU.

Former graduates hold professional positions in government, academia, and industry.

NIEHS Training Grant in Toxicology

 Oregon State University (OSU) offers interdisciplinary training in toxicology through its predoctoral degree program in the Department of Environmental and Molecular Toxicology and through postdoctoral fellowships. The NIEHS Training Grant offers financial support and provides unique research opportunities to selected predoctoral candidates and postdoctoral fellows. Support is available on a competitive basis to applicants with a B.S., M.S., or Ph.D. in chemistry, biochemistry, pharmacology, toxicology, or the biological sciences.

A limited number of graduate fellowships are also available through the Linus Pauling Institute.

Training Grant Faculty

Affiliated faculty members provide challenging basic sciences academics while mentoring students as they develop individual projects; this intensive course of studies leads to the M.S. or Ph.D. degree in toxicology. Training is provided in diverse areas including analytical, aquatic, biochemical, comparative, environmental and molecular toxicology with an emphasis on a mechanistic approach. Research projects focus on some aspect of toxicology or environmental health.

Balz Frei, Ph.D., Director, LPI, OSU Study the mechanisms of atherosclerosis and the modulatory effects of antioxidants, essential minerals, and micronutrients. Investigate the mechanisms and consequences of endothelial dysfunction, the role of pro-oxidant transition metal ions such as iron and copper in this process, and the effectiveness of vitamin C, lipoic acid, and flavonoids in ameliorating endothelial dysfunction. Find new, effective strategies to prevent or treat heart disease and stroke by dietary means or supplements.
Allison Fryer, Ph.D., Dept. of Physiology & Pharmacology, OHSU A major feature of asthma is eosinophils in the lungs. Fryer and her trainees have demonstrated that parasympathetic nerves in the lung are actively engaged in recruiting eosinophils to nerves via expression of chemotactic factors and adhesion molecules. They are investigating regulation of these signals. New data suggest that eosinophils have additional roles, important in modulating peripheral nerve function. They are investigating the role of eosinophils in nerve repair and plasticity.
Tory M. Hagen, Ph.D., Prof., Biochemistry and Biophysics, LPI, OSU Understand the basic biochemical mechanisms of aging and the ways in which micronutrients may promote health in the elderly. Identify precise gene-nutrient interactions that improve xenobiotic and oxidative stress response, which otherwise markedly declines in the elderly. Translate the knowledge gained in rodent models of aging toward developing strategies that may prolong human “healthspan”—the time of life full of vitality and free of disease.
Stacey Harper, Ph.D.
Asst. Prof., EMT, OSU;
Harper and her lab investigate the environmental, health and safety impacts of nanotechnology in order to support the responsible development of this rapidly growing industry. Our current lack of information on the environmental fate and toxic potential of nanomaterials prohibits us from performing valid risk assessments. Issues of particle behavior, bioavailability and toxicity are central to quantitative risk assessment. Studies in the Harper laboratory are designed to effectively improve our understanding of how and why nanomaterials interact with and sometimes alter living systems.
Emily Ho, Ph.D.
Assoc. Prof. of Nutrition and Exercise Sciences, OSU, LPI
