For a while, I thought my research focuses have been fairly random exploring many sectors of interests without much connection each other, including hydrogel adhesion (mechanisms to applications), 3D printing (mechanical isms to active materials), and conducting polymer hydrogels (materials to fabrication).
Interestingly, I find that all these scattered topics are now covering into one place under relatively well categorized forms. With this, getting new ideas and writing papers become much easier than before - I already submit two papers in the last 3 weeks, two more in next two weeks, one more before this September, and maybe one or two more before this December, all first authored. It is unexpected, but enjoyable development after all. All these laborious exploration and meandering in my early grad school days probably be finally paid off. Hopefully, this converting theme can be long-term one to fuel my curiosity and career in the future.
