I am a professor in the School of Informatics, Computing, and Engineering and a member of the Center for Complex Networks and Systems Research at Indiana University, Bloomington. My background is in Statistical Mechanics, and my research interests are in the area of complex networks and computational social science. Before joining IU, I held research positions in the Cavendish Lab. at the University of Cambridge, the Ralph Parson Lab. at the Massachusetts Institute of Technology, and the Center for Ultra-structural Analysis at University of Lausanne.
