Dr. Gardner's research interests in plant physiology include photobiology and photomorphogenesis, mode of action of plant growth substances, and naturally occurring compounds in plants that benefit human health. His photomorphogenesis research attempts to identify settings in which manipulation of phytochrome relationships can result in practical agricultural benefit. In this way, research on the role of phytochrome in the natural environment can be extended to the role of phytochrome in the managed environment. Since 2005, his photobiology research has also had a major focus on how plants perceive UV-B irradiation (280-320 nm) in the environment. In recent years, his work on plant growth substances has, in collaboration with Jerry Cohen, focused on the interaction of transport and synthesis of the plant hormone auxin. Dr. Gardner is a member of the graduate faculties in Plant Biological Sciences and Applied Plant Sciences, the Advisory Board of the Healthy Foods, Healthy Lives Institute, and the Executive Committee of the Consortium on Law and Values in Health, Environment & the Life Sciences.
