Welcome to the Circadian Cancer Biology Group (CCBG) at Tulane University School of Medicine. The CCBG provides an organizational structure to promote, enhance, and coordinate research and educational activities among circadian rhythm and cancer researchers at Tulane University and the Louisiana Cancer Research Consortium. The primary goal of the CCBG is to promote discoveries in the field of biological timing and the circadian system, as they relate to the biology of cancer and the host/cancer balance. This program is also committed to the education and training of researchers at all levels and in diverse disciplines, with circadian biology and cancer as a research focus. Furthermore, the CCBG is dedicated to educating the public regarding the emerging the health issues related to the consequences of circadian disruption on cancer and related diseases, as well as to serve as a resource of information for those seeking to know more about biological timing, circadian rhythms, circadian disruption and cancer.
