Muhammad Ali Khan is a Research Fellow at CERP. He is the Abram Hutzler Professor of Political Economy with the Department of Economics at The Johns Hopkins University. His research interests include economic interaction, as formalized in general equilibrium theory: models with a representative agent, as well as those with a finite number and a continuum. His interests in literature and epistemology are complemented by those in mathematics, where he works with methods of nonstandard analysis (Loeb spaces), non-smooth analysis and optimization (Mordukhovich-Ioffe cones), chaotic dynamics and stochastic processes (law of large numbers with a continuum of random variables). Dr Ali has a PhD and M Phil from Yale University, B.Sc. (Econ.), 1st Class Honours from the London School of Economics.
