It has been a true honor for me to serve as a Guest Editor for this Special Issue of The Journal of Polymer Science, Part B: Polymer Physics. This experience has provided me with invaluable knowledge and has helped me grow as a scientist and member of the Polymer Physics community. I thank the editors and publisher for this opportunity. When Dr. Sanat Kumar invited me to serve as a Guest Editor a few years ago, I thought about what new topics I would like have in this Special Issue, who to invite and how to organize it. Thankfully, Polymer Physics has become a very active and very broad field of research nowadays with ramifications in many other scientific fields. Thus, in this issue, I have tried to capture some modern aspects of Polymer Physics. One of the objectives of this Special Issue is to identify new concepts and problems in Polymer Physics or problems in other areas of science where our knowledge of Polymer Physics can make a significant contribution. In this part, the reader will find new research directions and also speculations that deserve our attention. I have also reserved a section for novel computational methodologies, that is, analytical theory and computer simulations, that can be used to address novel or long-standing, still unresolved problems. This part of the issue includes novel algorithms and numerical methods, and their application to address a particular problem in Polymer Physics. The last area is the one of review articles where the advances in many very interesting topics are clearly presented.
Fifty-one scientists were invited to contribute articles for this Special Issue. Twenty accepted the invitation and nineteen submitted manuscripts. I thank all of them for their help with this issue. I also thank all the referees for spending their invaluable time reviewing the manuscripts. Finally, but not least, I thank Hope Inman for helping me organize this issue.
