Assistant Professor

About Me


Dr. Umberto Celano is an assistant professor with the Faculty of Science and Technology at the University of Twente (Netherlands) and principal member of technical staff at imec (Belgium). His research agenda is focused on nanoelectronics at the interface of condensed matter physics, materials analysis, and semiconductor technology. He studies emerging devices and their physics with emphasis on the design and development of characterization methods for new materials, failure analysis, and correlative metrology. As such, his work is inherently multidisciplinary in nature blending device physics, and reliability with materials science and metrology.

Umberto Celano is a trained electrical engineer from the University of Rome Sapienza (Italy). After a master’s in nanoelectronics, he joined imec for his PhD in the laboratory of Wilfried Vandervorst (2010) where he got interested in materials analysis for semiconductor technology. During this period, he mastered multiple analytical techniques and focused on scanning probe microscopies, working to establish a novel three-dimensional nanoscale imaging technique to study materials in confined volumes (this work got him the 2013 IEDM Roger Haken Award). He received his Ph.D. in Physics from the University of Leuven - KU Leuven (Belgium) in 2015. Later, he joined imec as a permanent researcher, contributing in various roles to the materials/process development and characterization of advanced logic and memory devices. In 2018, he was a visiting scientist with the Geballe Laboratory for Advanced Materials at Stanford University where he expanded his research interest to functional materials in the realm of nanophotonic.
