  • Jeffrey Rosen, Professor

    University of Delaware
    227 Wolf Hall
    Newark, DE 19716


    ​Jeff Rosen's lab studies the neurobiology of emotion, focusing on conditioned and unconditioned fear, and how research in animals can be translated to fear and anxiety disorder in humans. The research primarily uses Pavlovian fear conditioning and unconditioned, innate fear of predator odors to study the fundamental neural circuits involved in fear.  This is approached from a neural systems perspective where neural circuits from sensory perception through motor output during emotional experiences are delineated at the neuroanatomical, cellular and molecular, and behavior levels of analysis. A major theme that has reoccurred over many studies is that the neural circuitry and pharmacology for learned fear is different from that for innate fear. In addition to its importance for basic understanding of brain systems during different types of fear, the research is performed with an eye towards translational significance for anxiety disorders in humans. Dr. Rosen's lab also teams up with a number of other labs to study fear conditioning in developing animals, the effects of early exposure to predator odors on expression of fear and anxiety in later life, and molecular correlates of early aversive and affiliative experiences in humans. The research has been funded throughout with grants from the National Science Foundation, National Institutes of Health, the Defense Department, and research foundations.
