Nicolas Lux FawziAssistant Professor of Molecular Pharmacology, Physiology and Biotechnology
Nicolas Fawzi received undergraduate degrees in bioengineering and marketing at the University of Pennsylvania. He received a Ph.D. from the Joint Graduate Group in Bioengineering at the University of California, Berkeley and UCSF for his work with Teresa Head-Gordon on molecular simulation of protein aggregation, and completed postdoctoral training in the group of G. Marius Clore at the National Institutes of Health in biomolecular NMR spectroscopy of protein association and aggregation. Nicolas Fawzi joined the faculty at Brown in January 2013.

My laboratory studies the structure, dynamics, and molecular interactions of protein aggregates implicated in neurodegenerative disease. Using a combination of novel NMR spectroscopy approaches and atomistic simulation supplemented by biophysical and imaging methods, we determine high-resolution structures of these species and their toxic interactions with other macromolecules and membranes, as well as their interactions with potential therapeutic agents.
The goal of my research group is to determine the structure and elucidate the molecular mechanisms of toxicity of aggregated and aggregation-prone states of proteins in neurodegenerative disease. My current aims are directed at RNA-binding proteins involved in ALS and frontotemporal dementias as well as amyloid-β aggregation associated with Alzheimer's Disease.
