The Sister Study


Studying aging and disease risk

Dr. Jacob Kresovich is a Sister Study researcher and post-doctoral fellow in the Epidemiology Branch at NIEHS. His research explores how a naturally occurring chemical modifications to DNA, called DNA methylation, are related to aging and disease risk. He previously showed that a higher ‘biological age’, as measured changes to DNA methylation, was associated with increased likelihood of developing breast cancer. Currently, he is studying how biological aging is affected by modifiable lifestyle factors such as physical activity and alcohol use.
