Invited Seminar at Norwich

On 3rd February 2016, Danilo Roccatano visited the School of Computing Science of the University of East Anglia in Norwich hosted by Dr Steven Hayward. He gave the invited seminar:

Study of Interaction Mechanisms of Block Copolymers with Biological Interfaces

 Abstract

Polyethylene oxide and polypropylene oxide homopolymers as well as block copolymers based on them (Poloxamers or Pluronics®) have many applications in biotechnology and in pharmacology. This versatility is due to their biocompatibility and tuneable properties. Still the molecular mechanisms of their interactions with biological systems remain not fully investigated. A powerful and versatile approach to study these processes is the Molecular Dynamics (MD) simulation method that allows exploring these systems on scale of different order of magnitude in length and time. In the last years, we have developed for these purpose full atoms and coarse-grained models of these polymers that have been successfully tested against several experimental data in solution, and at interface with lipid bilayers. Using a recently proposed and developed Self Consistent density Field MD method, we also accomplished to perform large-scale simulations study of polymeric micelles formation and their interaction with lipid bilayers. These results have unrevealed possible mechanisms of single polymer and micelle interaction with lipid bilayers. In this talk, I will summarize the main achievements and future directions of these studies.

About Danilo Roccatano

I have a Doctorate in chemistry at the University of Roma “La Sapienza”. I led educational and research activities at different universities in Italy, The Netherlands, Germany and now in the UK. I am fascinated by the study of nature with theoretical models and computational. For years, my scientific research is focused on the study of molecular systems of biological interest using the technique of Molecular Dynamics simulation. I have developed a server (the link is in one of my post) for statistical analysis at the amino acid level of the effect of random mutations induced by random mutagenesis methods. I am also very active in the didactic activity in physical chemistry, computational chemistry, and molecular modeling. I have several other interests and hobbies as video/photography, robotics, computer vision, electronics, programming, microscopy, entomology, recreational mathematics and computational linguistics.
