Research in the Seyfried lab is focused on the integration of proteomics, systems biology, and molecular biology to tackle fundamental questions related to the pathogenesis of Alzheimer’s Disease (AD) and other neurodegenerative disorders. In particular, we utilize high resolution liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) to identify and quantify proteins and post-translational modifications (PTMs). Combining tools in both molecular and cellular biology, we also explore the relationship between the function of these proteins and their PTMs in the development of these devastating diseases.
