University Teaching

Dr. Henderson is currently an Assistant Professor at the University of Florida in the Environmental Engineering Sciences department. His interests are the chemistry and physics of air pollution as it relates to human health, ecological health, and climate change. Dr. Henderson currently teaches a graduate class called "Global Air Pollutants" and an undergraduate course called "Energy & Environment." "Global Air Pollutants" focuses on the modeling of chemistry and physics at the global scale with a focus on persistent organic pollutants, mercury, ozone, and aerosols. "Energy & Environment" focuses on understanding the limitations and trade-offs of energy sources in the context of present and future societal uses. He has also taught "Foundations of Air Pollution," and regularly guest lectures in other courses on the scientific, regulatory and public health implications of air pollution and climate change.
