Cristiano is an Associate Professor in the Department of Physics at NJIT where he runs the Dias lab in computational biophysics. The lab uses multiscale models that can bridge atomistic and mesoscopic length scales to provide a better understanding of biological systems and diseases. Enhanced sampling methods as well as brute force molecular dynamics simulations are used to study these systems. The lab also develops new simulation methods whenever needed.

‚ÄčMain research interests: (i) the structure of amyloid proteins and their aggregation into oligomers and fibrils related to senile plaques in the brain of Alzheimer's patients, (ii) effect of organic molecules/drugs on the structure and aggregation of amyloid proteins, (iii) interactions of amyloid fibrils and lipid bilayers, (iv) allosteric effects in enzymes, and (v) formation of methane clathrates at the atomic level.

Several of the research projects in the Dias lab are performed in collaboration with experimental and theoretical partners. Thus, do not hesitate to contact us if you are interested in collaboration.

Research Interests

Dr. Dias uses theory and computer simulations to understand emerging phenomena at the interface of Physics, Biology, and Chemistry. His group uses all-atom models and develops coarse-grained models to study equilibrium and non-equilibrium phenomena in molecular Bio-Physics. Dr. Dias seeks to decipher: (i) microscopic mechanisms accounting for the aggregation of peptides into amyloid fibrils, (ii) how these fibrils interact with each other accounting for the bulk properties of biomaterials, and (iii) how they interact with micelles/cells. These efforts are of paramount importance for the design of new drugs to treat diseases that result from misfolding and/or aggregation, to understand biological and cellular functions at the molecular level, and to design new biomaterials.
