B.S., Slippery Rock University; M.S. and Ph.D., University of Illinois. His research examines the neurochemical basis of biological time keeping. Dr. Weber joined the Rider faculty in 2001.

Education

  • 1999-2001 Research Assistant Professor, University of Houston, Houston, TX

Research Interests

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 chronic circadian disruption on behavior, physiology and neurochemistry in mice.

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 various physiology and neuroscience journals.  Students working on these projects are pursuing careers in research, graduate school, medicine, the pharmaceutical industry and others.

Independent Projects

Biology, Behavioral Neuroscience, Biochemistry or Health Science students with an interest in physiology, neuroscience and behavior are invited to speak with Dr. Weber about the possibility of research projects (BNS/BIO-490).  Studies of circadian rhythms can be approached using a broad range of tools, including physiological tests, immunohistology, neurochemistry, and behavioral analysis.  It is anticipated that students successful in their research ventures may co-author published, peer-reviewed science manuscripts, make poster presentations of their research findings in the Rider science community, and attend national scientific conferences.
