Research activities: The primary focus of my research is to investigate the role of lipid oxidation in chronic diseases. In particular, I am investigating oxysterol involvement in Alzheimer’s disease and chronic kidney disease. My work has shown that oxysterol -treated neuronal cell viability was decreased, associated with a decrease in redox potential and an increase amyloid beta secretion through lipid raft formation. I developed a simple blood-brain barrier model to investigate the oxysterol mobility. Recently, I have developed a high sensitive targeted liquid chromatography and mass spectrometry (LC-MS/MS) based multiple reaction monitoring (MRM) method to quantify oxysterols in cells, tissue and biological fluids.
