Biswas is the  Glidden Visiting Professor from the University of Southern Mississippi.

Abstract: In this talk, I will address the problem of designing complex material as an inverse problem, and show that many aspects of structural and electronic properties of amorphous materials can be understood better from an inverse or a hybrid point of view.  In particular, I will discuss how the distribution of hydrogen in amorphous silicon can be obtained by inverting experimental nuclear magnetic resonance spectra in conjunction with first-principles density-functional calculations.  New results concerning two important aspects of hydrogen microstructure, such as voids and molecular hydrogen, will be presented in this talk.
