Research Description:

My scientific philosophy is that I want to find true, clinically relevant and widely applicable mechanisms of disease. Therefore, my lab employs multiple models, from cell-free to animal models, multiple techniques, including metabolomics, histology, genetic manipulations, and pharmacological approaches to tackle complex biological questions. The current research focuses on how N-link glycans affect metabolism and disease progression in Ewing's Sarcoma and late-onset Alzheimer's disease.
