About Our Center
The Marshall Center, led by Lynn Marshall, Sc.D., conducts epidemiologic and clinical research on musculoskeletal conditions. Dr. Marshall’s research is informs public health and clinical practice by identifying risk factors for musculoskeletal conditions. This information can used to improve our ability to identify and intervene on high risk groups. Dr. Marshall has extensive training in statistical methods and brings a strong quantitative focus to her research. She actively collaborates with many health professionals, including biostatisticians, molecular biologists, surgeons, physiatrists, and physical therapists, both within and outside of OHSU. In addition to her scholarly activities, Dr. Marshall contributes to the teaching and service missions of OHSU as well. She is a research advisor and mentor to OHSU medical students, Orthopaedic residents, and graduate students. She serves as a Vice Chair of the Institutional Review Board (IRB).
• Low back pain, orthopaedic spine conditions associated with low back pain, and their long outcomes in older adults
• Risk factors for accidental falls and for bone fractures in older women and men
• Factors associated with bone loss and changes in physical functioning during aging
• Outcomes associated with lower urinary tract symptoms severity in older men
• Measurement of biologic phenomena, including assays and body composition imagingThe Marshall Center is collaborative, involving not only epidemiologic methods and statistical analysis but also disciplines that guide investigation of biologic mechanisms and clinical relevance.
