RESEARCH INTERESTS
My scientific research interests are focused in the fields of Structural Biology / Molecular Biophysics. More specifically, I am dealing with:

1. Structural and self-assembly studies of silkmoth chorion peptide analogues as novel self-assembled polymers with amyloid properties. These studies may lead to the construction of novel biomaterials with extraordinary physical properties. We determined that silkmoth chorion is a natural, protective amyloid and we proposed, for the first time worldwide, the existence of natural, functional amyloids. Currently, we are also experimentally studying the role of a great variety of amyloidogenic ('aggregation-prone')-peptides, predicted by our AMYLPRED prediction algorithm, in several widespread and also rare pathological amyloidoses. We are particularly interested to 'hack' the amyloid code, if such a code exists.

2. Structural and self-assembly studies of fibrous proteins, which form extracellular, proteinaceous structures of physiological importance like lepidopteran, dipteran and fish chorions. Model structures of silkmoth chorion proteins and their interactions have been proposed. Also, we are studying chitin-protein interactions for the formation of arthropod cuticle. We have recently proposed a model structure of cuticular proteins and we developed a universal, freely available through the Internet, cuticular protein relational database.
