Jim Kaduk is an Adjunct Professor of Chemistry at the Illinois Institute of Technology and President and Principal Scientist of Poly Crystallography Inc. He began his crystallographic career as an undergraduate at Notre Dame. After obtaining a Ph.D. in inorganic chemistry at Northwestern in 1977, he joined Amoco Chemicals and did catalysis R&D for eight years. He ran the X-ray diffraction lab in the Analytical Science Research Services group of Amoco/BP/Innovene/INEOS from 1985-2009. This lab characterized a very wide range of materials, including catalysts, inorganics, corrosion deposits, organics, and polymers. Jim is well known for his expertise in solving and refining crystal structures using powder diffraction data, and for combining crystallography and quantum mechanics to understand not just where the atoms are, but why they are there. His current work involves citrate salts, catalysts, pharmaceuticals, and long skinny molecules.
