Richard J. Sherwood, Ph.D., Director, Professor, Departments of Community Health and Pediatrics; Co-Director, The Fels Longitudinal Study

Dr. Sherwood is a comparative anatomist with specific interest in the forces influencing variation in the craniofacial complex. His current research is directed at elucidating the longitudinal modelling of craniofacial phenotypes as well as dissecting the genetic influences on the craniofacial complex. His research has included paleoanthropological fieldwork in Kenya and Tanzania and analysis of fossils from those regions.

Dana L. Duren, Ph.D. Associate Professor, Departments of Community Health and Orthopaedic Surgery; Director of Orthopaedic Research

Dr. Duren has research specialty in bone and joint health across the life span. She examines genetic and environmental influences on pediatric bone health, endophenotypes of osteoarthritis, musculoskeletal outcomes following weight-loss surgery, and influences on dynamic gait in children, the elderly, and the obese.

Major Active Projects

Dr. Duren is dedicated to improving pediatric skeletal health. She directs successful research programs on the influences on cortical bone accrual during childhood and the later adulthood consequences, and has made significant strides in revamping standards for assessing skeletal maturity from the hand-wrist radiograph. Her current goals are to unite clinical and basic scientists to conquer all barriers to the best practices in maturity assessment. Her lab has recently completed the first phase of data collection for updating skeletal maturity methods to include multiple races and contemporary children. She is also making strides in achieving a semi-automated computer program to accelerate the use of the FELS method for maturity assessment in collaboration with biomedical and computer engineers and clinical pediatric radiologists.

Through the analysis of data from the 80 year history of the Fels Longitudinal Study, Dr. Duren and her team are uncovering a number of important secular trends in the developing skeleton. Root causes of these trends are still unclear. Novel avenues for exploring the underpinnings and consequences of these changes in the skeleton are key areas of exploration and expansion in the Duren lab.

In her overarching theme of Bone and Joint Health Across the Life Span, she also directs research on the following:

1. Genetics of the Pediatric Skeleton

2. Osteoarthritis and Health of Joints and Cartilage

3. Three Dimensional Analysis of Gait and Function

Ramzi W. Nahhas, Ph.D. Assistant Professor, Department of Community Health

Dr. Nahhas is a biostatistician whose interests include both statistical methodology and applying statistical methods to scientific questions. His current research includes longitudinal modeling of craniofacial growth, updating the FELS Method of skeletal maturity assessment, body composition and cardiometabolic risk, latent class analysis of drug abuse, construction of conditional growth standards, and missing data.

Andrew W. Froehle, Ph.D. Assistant Professor, Department of Community Health

Dr. Froehle's research focuses on the effects of development and aging on changes in physical performance (walking gait and exercise capacity) as indicators of disease or compromised function. He is particularly interested in the manner which hormonal changes at menarche and menopause influence physical performance by affecting metabolic processes. Study populations include the Fels Longitudinal Study, bariatric weight-loss surgery patients, a cohort of postmenopausal exercisers in San Diego, CA, and Wright State student athletes.
