Dr. Bijan Najafi and his team at Baylor College of Medicine are part of the newly established Precision Aging Network, which will focus on how and why individuals experience aging differently. Led by the University of Arizona, the network was established through a five-year, $60 million grant from the National Institutes of Health. The multisite study will recruit 275,000 individuals over the age of 60 and collect genome, DNA, biomarkers and other data from them. Under the leadership of Dr. Bijan Najafi, professor and director of clinical research in the division of vascular surgery in the Michael E. DeBakey Department of Surgery at Baylor, the Baylor team will focus developing a better understanding of the link between mobility and cognitive brain aging using wearable technology to collect information about sleep, stress and physical activity. They also will collect data on cognitive frailty.
