Expert has over 50 years experience in ceramic materials and processing. He is an expert on electrical ceramics
and has received numerous awards. He has both industrial and academic experience, and is active in the
American Ceramic Society, having held all positions in the Electronics Division, including past Chair. Expert directs
an electrical ceramics research program at the University of Illinois at Urbana-Champaign and has published nearly
300 papers and12 patents, and graduated 60 Ph.D. and M.S. graduate students. Most of the research has been
involved with advanced materials processing through the use of new and improved starting materials and the
control of microstructure. He is an expert on structure-property relations. In the past decade he has pioneered the
chemical-solution processing of ferroelectric thin films at greatly reduced temperatures, which has led to materials
integration with semiconductors and new products. Other notable achievements by his research group include the
crystal growth of highly efficient piezoelectric materials, and novel methods of additive patterning by microcontact
printing with self-assembled monolayers. Expert continues to be at the forefront of developments in advanced
materials processing of electrical ceramics and is a consultant to industry.
