研究领域

My research interests are to understand the effects of naturally occurring and man-made chemicals on immunity, development, and homeostasis. Specific chemicals of interest are halogenated aromatic hydrocarbons, pesticides, ethanol, and botanical dietary supplements. These compounds are thought to impact health and development through direct mechanisms, such as altered gene expression, or indirectly through alteration of hormone levels and other pathways. The focus of my laboratory is to investigate mechanisms of toxicity at the organismal, cellular, and molecular levels with the ultimate aim to improve human and animal health.
