Ivan K. Schuller (born 1946 in Romania) is an American condensed matter experimental physicist. He is born 1946 in Cluj, Northern Transylvania, which belonged to Hungary until 1947. ^[1] He is best known for his work on superlattices. His interests are focused on thin films, nanostructures, novel materials, magnetism, and superconductivity.

The Romanian-born Schuller received his Licenciado (1970) from the University of Chile, MS degree (1972) and PhD (1976) from Northwestern University. From 1978 to 1987, he was a senior physicist and group leader at Argonne National Laboratory. Since 1987, he has been a professor of physics at the University of California, San Diego; in addition to this position, he is also Layer Leader-Materials and Devices of CAL-(IT)2 Institute, and director-AFOSR-MURI at UCSD. He held visiting professorships at the Catholic University - Santiago, Chile; Universidad del Valle, Colombia; the Catholic University-Leuven, Belgium, the Rheinisch-Westfälische Technische Hochschule Aachen, Germany, Universidad Complutense de Madrid, and University of Paris.

Currently he is a Distinguished Professor and holder of Research Chair V of the Center for Memory and Recording Research (CMRR) at the University of California San Diego.
