Karen J. Bandeen-Roche, PhD

Dr. Bandeen-Roche

Dr. Karen Bandeen-Roche is the Frank Hurley and Catharine Dorrier Professor and Chair of Biostatistics at the Johns Hopkins Bloomberg School of Public Health.  She received her Ph.D. from Cornell University in Ithaca, NY.   In addition to a biostatistician she is a gerontologist who has invested nearly 20 years of commitment to scholarship on aging.  Her gerontological research has been focused on the causes and course of physical disability and the measurement and physiological etiology of frailty and aging.  She served as the Interim Director of the Johns Hopkins Center on Aging and Health between 2008 and 2012, co-directs the Johns Hopkins Older Americans Independence Center, and directs both its Biostatistics Core and that of the Johns Hopkins Alzheimer’s Disease Research Center.  In addition to these roles she has served as the principal statistician on the Women’s Health and Aging Studies (WHAS), Salisbury Eye Evaluation studies (SEE), and the Baltimore Memory Study and served as Johns Hopkins site P.I. of the WHAS.  She directs the Johns Hopkins Training Program on the Epidemiology and Biostatistics of Aging, which she co-founded in 1996.  She is one of two statisticians named as a Brookdale National Fellow over its history. 

As a Brookdale Fellow, Dr. Bandeen-Roche: (1) developed and validated new regression methods for statistical analysis of multiple outcomes collected in longitudinal studies of disability in older persons; (2) developed statistical software that implements the new methods; (3) assessed the relative advantages and disadvantages of the new methods and their existing counterparts, by applying each to important gerontologic data sets. The methodologic advances from this research will enable scientists involved in intervention trials and epidemiologic studies on aging to more efficiently investigate physical functioning and its causes and modifiers. It is hoped that the new methodologies will improve our understanding of what determines functioning and ultimately contribute to the mitigation of disability in older populations.          
In biostatistics Dr. Bandeen-Roche has published extensively on statistical methods to analyze longitudinal and time-to-event analysis as well as for complex measurement, including the development of latent variable models to describe syndromal outcomes such as frailty, assess their internal validity, and evaluate the degree to which hypothesized theoretical determinants affect targeted outcomes as opposed to their individual symptoms and signs.  She is a Fellow of the American Statistical Association, Chaired the NIH Study Section on Biostatistical Methods and Study Design (2006-8), and held multiple leadership roles in statistical professional societies including most recently election as President of the International Biometrics Society’s Eastern North American Region (2012).
