Howlett, Susan - Dalhousie University - Department of Pharmacology

研究领域

Dr. Howlett is best known for her work on cardiac contraction. She has discovered profound differences in the way male and female heart cells function and how this changes with age. She has pioneered the measurement of frailty with a "frailty index" in aging animals, a major advance that will help translate scientific discoveries in aging research into meaningful clinical interventions.
