John Perepezko

John Perepezko is a Professor in the Department of Materials Science and Engineering at the University of Wisconsin-Madison, within the College of Engineering. His work focuses on alloy solidification, phase transformations, and microstructural design under extreme conditions.

• PhD, Carnegie-Mellon University (1973)
• MS, Polytechnic Institute of New York (1968)
• BS, Polytechnic Institute of New York (1967)

Research interests include phase transformations, interface reactions, metastable phases, kinetics, nucleation, metal powders, superalloys, and microgravity processing. He investigates crystallization mechanisms in amorphous alloys and self-healing coatings via kinetic biasing.

Recent publications emphasize high-temperature oxidation, metallic glasses, radiation effects, and Multiphase microstructures. Key themes include predictive modeling of coating behavior, nanocrystal synthesis, and advanced refractory alloy design.
