Director, Translational Research Training Program in Gerontology and Geriatrics
Co-Director, Biology of Frailty Program, Johns Hopkins School of Medicine
Schools\degrees: Oberlin College\AB Chemistry; University of Illinois at Champaign-Urbana\PhD Biochemistry
Training: National Institutes of Health Postdoctoral Fellowship
Research summary: I received an A.B. in Chemistry from Oberlin College in 1980 and a Ph.D. in Biochemistry from the University of Illinois at Champaign-Urbana in 1987. After post-doctoral work at the National Institutes of Health, I was recruited to Johns Hopkins University in 1992 where I am currently a Professor in the Division of Geriatric of Medicine and Gerontology. My research interests include age-related dysregulation of tissue remodeling, cellular differentiation and apoptosis; with an emphasis on tumor progression.
