John Hildebrand

John Hildebrand is a Regents Professor at the University of Arizona, holding concurrent appointments in Neuroscience, Chemistry & Biochemistry, Entomology, and Molecular & Cellular Biology. His research focuses on the neurobiology of insect olfactory systems, particularly in Manduca sexta moths, exploring how sensory inputs guide behavior. He investigates mechanisms of odor detection, neural circuitry in antennal lobes, and the developmental plasticity of olfactory systems. His work also addresses applied issues like vector control for Chagas disease via Triatomine insects.

Research highlights include studies on pheromone processing, plant volatile interactions, and the role of neuromodulators like serotonin. Hildebrand’s interdisciplinary approach combines electrophysiology, neuroanatomy, and behavioral assays. He has pioneered techniques for studying neural ensemble activity and insect-machine interfaces using carbon nanotube probes. His contributions span basic science and applied ecology, emphasizing cross-disciplinary collaboration.

Notable projects include elucidating how olfactory circuits encode odor mixtures, the developmental basis of sexually dimorphic neural structures, and the ecological implications of insect sensory systems. His lab has also characterized CO2 detection in moths and its role in host location. Hildebrand advocates for science policy and education, emphasizing the societal impact of biological research.
