Hari Singh Nalwa (Scientist)

Hari Singh Nalwa (born January 15, 1954) is an American scientist working in the fields of nanotechnology and materials science. He has authored more than 150 scientific articles, 25 book chapters, 18 patents (Hitachi Ltd., Japan), and 114 scientific books in the fields of nanotechnology, materials science and polymer science.

Nalwa received a Bachelor of Science (B.Sc.) degree in bio-sciences from the Meerut University in 1974, a Master of Science (M.Sc.) in Organic Chemistry from the Indian Institute of Technology Roorkee in 1977, and his PhD degree in Polymer Science/Physical Organic Chemistry from the Indian Institute of Technology Delhi in 1983. In his PhD, he studied the electrical and the thermal properties of macromolecular systems such as thiourea-based polymers and metallophthalocyanines. He worked as a guest scientist at the Hahn Meitner Institute (HMI) in West Berlin, West Germany in 1983–1984, and moved to the University of Southern California, Los Angeles, California in 1984 as a research associate. He moved to the State University of New York, Buffalo in 1987 and worked on nonlinear optics. In 1988, he joined the Tokyo University of Agriculture and Technology, Tokyo, Japan, as a lecturer/assistant professor and worked on conducting polymers and organic materials. In October 1990, he joined Hitachi Research Laboratory, Hitachi City, Japan as a staff scientist. While working at Hitachi Ltd., he was concurrently an honorary visiting professor at IIT Delhi. He resigned from Hitachi Ltd. in 1999 and returned to the United States. He worked as the head of department and R&D manager at Ciba Specialty Chemical Corporation (Ciba-Geigy, Switzerland) in Los Angeles, California for a year (1999–2000), thereafter, he resigned to start his own business entitled "American Scientific Publishers" focused on nanotechnology.

Nalwa’s research includes electrically conducting polymers, nonlinear optical materials for integrated optics, ab initio calculations, electroluminescent materials, low and high dielectric constant materials for microelectronics packaging, organic semiconductors, nanocrystalline and nanostructured materials, Langmuir-Blodgett films, high-temperature resistant polymer composites, epoxy-based photopolymers, rapid modeling, and stereolithography. He has made contributions to a wide spectrum of research areas from polymer science to materials science to nanotechnology and published many outstanding research papers and books. The "Handbook of Advanced Electronic and Photonic Materials and Devices", 10-Volume Set edited by Nalwa was published by Academic Press in 2001.
