GRACE: Geriatric Research in Ambulatory and Cognitive Excellence

Themes People Videos Talks Sponsors Publications Bibliography

Status: Completed

The GRACE program (http://collab.sam.pitt.edu/dev/grace) aims to connect neurological aging with mobility impairment in older adults through medical imaging, mathematical analysis and computational tools. The program goals are to: 1) Implement efficient automated procedures for correlating multiple mobility factors with cognitive measurements, 2) Develop new practical regression algorithms capable of handling very large databases of measurements, 3) Design novel visual paradigms for effective mining and communication of multidimensional and multicomponent correlations between observed ambulatory characteristics and cognitive measurements. GRACE connects in this effort the University of Pittsburgh Departments of Computer Science, Epidemiology, Mathematics and the Center for Simulation and Modeling.
