Dr. Weber’s research addresses the organization of mammals’ physiology and behavior into circadian (daily) rhythms by the nervous system. Experiments in the lab address how the circadian system influences other aspects of physiology & behavior. Current student projects include studies of jetlag at behavioral, physiological and neurochemical levels in mice.
A second line of research investigates neurogenesis in the hippocampus of mice, one of only two brain areas in mammals where neuronal proliferation occurs throughout adulthood. Persistence of this trait in such limited areas suggests an important role in brain function, but neither the necessity of this process nor the role it plays in hippocampal function have been elucidated. Student projects in Dr. Weber's lab are examining the result of severely inhibiting this process through the use of antimitotic chemotherapeutic drugs traditionally used for treatment of cancer, to observe for potential behavioral or cognitive consequences.
Results of these projects have been presented by students at national conferences of the Society for Research on Biological Rhythms and the Society for Neuroscience, and have been published or submitted for publication in neuroscience journals. Students working on these projects are pursuing careers in graduate school, medicine, and pharmaceutical industry.

Biology/ Biopsychology/Biochemistry majors: Students with an interest in neuroscience and behavior are invited to speak with Dr. Weber about the possibility of independent research projects (BPY/BIO-490) or work study. Studies of circadian rhythms can be approached using a broad range of tools, including molecular biology, electrophysiology, anatomy & histology, neurochemistry, and behavioral analysis. It is anticipated that students successful in their research ventures will co-author published, peer-reviewed science manuscripts, make poster presentations of their research findings in the Rider science community, and attend national scientific conferences.
Interdisciplinary students: Library projects for students interested in interdisciplinary issues may be selected from topics that deal with the broad range of physiological and behavioral phenomena that are affected by the circadian system – for example, sleep & sleep disorders, jetlag, many mental disorders, timing of chemotherapeutics and other pharmaceuticals, hormone cycles, reproductive function. Other topics to match individual student interests are also possible.
