Education:   Creighton University School of Medicine
 
Teaching:
Dr. McCumber’s teaching interests are in gross human anatomy and histology with specific interest in dynamic small group and laboratory activity in relation to student learning and retention. Dr. McCumber participates in the Structure and Development of the Human Body course for medical, physician assistant, physical therapy, and graduate students; as well as medical Cellular Processes and Function of the Human Body Cores. Additionally, Dr. McCumber serves as the Director of UNMC Gross and Advanced Anatomy Laboratories.

Research:
Dr. McCumber’s research interests are related to mechanical regulation of bone tissue with specific interest in bone and immune system interactions. Mechanical loading of bone is necessary for maintaining bone structure and strength; however, repetitive loading can lead to fatigue induced microdamage. Tissue damage and the accumulation of microcracks within mineralized bone matrix results in increased bone fragility. Targeted bone remodeling is the localized remodeling and repair of bone tissue microdamage via the coupled interaction of intra-cortical osteoclasts and osteoblasts. The mechanism initiating intra-cortical osteoclasts for the targeted removal of microdamage has yet to be fully described. Ongoing studies are focused on bone and immune cell signaling interactions in relation to targeted bone remodeling and repair of fatigue induced microdamage.
