Peter Kozak

Chemical Engineer


Dr. Peter A. Kozak received his B.S. degree in aerospace engineering with a minor in mathematics from the University of Arizona in 2011 and his Ph.D. in Mechanical & Aerospace Engineering from the Illinois Institute of Technology in 2016. He first came to Argonne National Laboratory as a post-doctoral appointee in 2016 and is currently a chemical engineer in the Process Simulation and Safeguards research group in the Chemical & Fuel Cycle Technologies Division. Dr. Kozak’s research areas of interest include additive manufacturing/3D printing applications for nuclear/chemical engineering and medical radioisotope development. Since his arrival at Argonne, Dr. Kozak has improved the versatility and reliability of centrifugal contactors, a solvent extraction device used for separation of chemical elements including nuclear fuel reprocessing and medical isotope production.
