Air quality research related to livestock production, especially quantification of ammonia, dust, and odor emissions in dairies, beef feedlots, and poultry operations. Main objective is to help establish environmentally benign livestock systems.

Environmental physiology research, focusing on effects of air emissions on animal health and welfare.

vogel Christoph Vogel, PhD
Asst Professor Researcher
Dept of Env Toxicology

Phone: (530) 752-1337

Dr. Vogel has conducted research in the area of molecular biology and toxicology. The main areas of his research are the structure and function of receptors for xenobiotics and molecular mechanisms of inflammatory gene expression. His specific focus is on inflammation-associated chronic diseases (for example, cardiovascular diseases) and carcinogenesis mediated by environmental pollutants such as dioxins and airborne particles. He will analyze the toxicity of particle samples collected on various dairy farms based on their inflammatory response elicited in a human macrophage model.
