Research description

Prof. Y. Alex Xue is a theorist who conducts research across the boundaries of traditional disciplines. His scholarly interests range from theoretical and computational studies of the electronic, atomic, and mesoscale processes in nanostructured systems to empirical and critical studies of the cultural, economic, and political processes involved in the rise of the knowledge society.
