Expert has 50 years of experience in ceramic processing and properties of electrical ceramics,
including capacitors,multilayer ceramic capacitors, insulators, dielectrics, inductors, resistors, thermistors, sensors,
transducers, varistors, superconductors, and thin-layer capacitors. He has 10 years of industrial experience and
36 years of university experience, has published nearly 300 articles and 12 patents, lead a large research
group,pioneered integrated ferroelectric films via sol-gel processing, and lectured on dielectric ceramics, ceramic
materials and properties,ceramic processing, and optical microscopy. He has been a consultant to the electrical
ceramics industry for over 40 years.

Expert's major area of research is directed at improving and developing new ceramic capacitor materials. He has experience with all types of ceramic capacitors and manufacturing methods. His emphasis is on interrelationships that exist in the processing cycle, and their manipulation to advantage, between composition, structure, and properties.

A professor of materials science and engineering/ceramic engineering, Expert teaches a variety of courses on advanced ceramic materials. These courses cover topics such as ceramic materials and properties, ceramic processing, dielectric ceramics, electrical ceramics, ceramic microscopy, and hybrid circuits. Expert also conducts an extensive research program on advanced electrical ceramics, which includes areas such as synthesis, crystal growth, processing, microstructure-property relations of ferroelectrics, antiferroelectrics, piezoelectrics, capacitors, superconductors, and magnetoresistance.

Expert has teaching, research, and industrial experience on ceramic processing and forming methods, including solid-liquid processing (suspensions, casting, extrusion), powder processing (granulation, pressing), and thermal processing (firing, drying). He has expertise on the ceramic processing of multilayered capacitors and packages by tapecasting methods. He has also established a hot-pressing facility.

Expert has over 10 years industrial experience and 36 years academic research activity on ceramic capacitors,
including high voltage, disc, tube, multilayer, and thin layer. He is very familiar with manufacturing methods,
testing, and
reliability issues.

Expert has established a research facility for ferroelectric and related materials--piezoelectrics, pyroelectrics, and electrostriction--with dielectric measurement and characterization capability as a function of temperature, voltage, frequency, and other variables. He is an expert on barium titanate- and lead zirconate titanate-based materials, their properties, and applications.

Expert's research group pioneered the deposition of ferroelectric thin films by sol-gel processing methods over 25
years ago. Since then, they have investigated many materials and dielectric issues, including size and scale
effects, and the role of residual stress on properties.

Expert is leading a research group on the sol-gel processing of electrical and optical ceramics. The group has carried out sol-gel processing of thin-layers and bulk ceramics for optical and electrical/magnetic applications. He has established a materials chemistry laboratory, with synthesis, processing, and characterization capability. Other areas of his expertise include the synthesis of metallo-organic precursors, polymeric sol-gel processing, thermal conversion to metal oxides, and stress measurements.

Expert established a crystal growth laboratory for ferroelectric, electrooptic, piezoelectric, and superconducting materials. His facilities include high-temperature crystal growth equipment, flux, and hydrothermal methods. He has experience with a wide range of materials and methods.

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.


Expert consulted on ferroelectric memories; he provided on-site assistance, technical evaluations, and testing.He consulted on PTCR sensors. He provided on-site trouble shooting, technical reviews, and materials characterization. Expert consulted on piezoelectric actuators, providing on-site evaluation, improved design, and better materials.He consulted on ceramic capacitors; he provided on-site product evaluation, process improvements, and quality assurance.
