My research interests centre around the physics and chemistry of polymers at surfaces and interfaces, heterogeneous media (gels), adhesion, semiconducting polymers, biophysics, and soft nanotechnology: https://www.markgeoghegan.org My team has developed a reversible glue that is inexpensive and scalable. We have also made it conductive, so that it competes with other such glues, but which cannot be reversed. This reversible adhesion is important for recycling technologies. I have written a book: Polymer Electronics by Mark Geoghegan and Georges Hadziioannou (OUP, 2013)
