Susan Abbatiello, a research scientist in the Broad Institute's Proteomics Platform, has lived with biomarkers since she was 5 years old. After being diagnosed with type 1 diabetes, she grew up aware of daily indicators of her health, measuring her blood sugar levels every few hours and balancing her insulin injections with how much she ate and how active she was. Now, as a Broad scientist, she hunts other kinds of indicators of health and disease: biomarkers in cancer that show up before the disease progresses to a life-threatening stage. Abbatiello brings a passion for mass spectrometry and quantitative analysis to developing a blood test that one day might flag cancer before a malignant tumor can be detected. Hear more about why she became a scientist and the kinds of projects she pursues at the Broad Institute.
