While at AIMS, Guy showed mathematically the existence of new cylindrical interface or stationary sets of the Ohta-Kawasaki functional energy which is a well studies model in block copolymer melt. He used Crandall-Rabinowitz bifurcation Theorem, to prove the existence of Delaunay-type surfaces which are critical points of the sharp interface limit of the Otha-Kawasaki model.

Guy is currently a Postdoctoral researcher at the University of Dresden, Germany. Prior to this, he obtained his PhD in Analysis (PDEs) from Bielefeld University, Germany
