Hisashi Kobayashi

Hisashi Kobayashi was born in Tokyo, Japan.[5] The mathematician Shoshichi Kobayashi (1932–2012) was Hisashi's elder brother.

Hisashi studied at the University of Tokyo, and completed a Bachelor of Engineering and Master of Engineering in electrical engineering in 1961 and 1963, respectively. He was a recipient of Sugiyama Scholarship (1958–61) and RCA David Sarnoff Scholarship (1960).[5] He worked as a radar system designer at Toshiba, Kawasaki in 1963–65.[6]

In 1965 Kobayashi came to the United States as a recipient of the Orson Desaix Munn Fellowship of Princeton University and received a PhD degree in electrical engineering in 1967.[5]

He worked for the IBM Thomas J. Watson Research Center at Yorktown Heights, New York, for fifteen years (1967–1982). He was a research staff member in its Applied Research Department from 1967 to 1970, where he worked on seismic signal processing, data transmission theory, digital magnetic recording, and image compression algorithms. In 1971 he moved to its Computer Science Department as Manager of the then newly created, "System Measurement and Modeling" group, was promoted in 1976 to Senior Manager of "Systems Analysis and Algorithms", and in 1981 became Department Manager of "VLSI Design".[7] During his tenure at IBM Research, he was granted sabbatical leaves to accept invitations from several institutions. He was a visiting professor at the University of California, Los Angeles (September 1969 – March 1970), University of Hawaii (July 1975 - December 1975), Stanford University (January 1976 - June 1976), Technische Universität Darmstadt (September 1979 – August 1980), and Free University of Brussels (September 1980 - December 1980).[6]

In 1982, Kobayashi was appointed the founding director of the IBM Japan Science Institute (later named as IBM Tokyo Research Laboratory) in 1982,[8][9][10] and served in that position until 1986, when he joined Princeton University's faculty as Dean of the School of Engineering and Applied Science (SEAS),[11] and the Sherman Fairchild University Professor of Electrical Engineering and Computer Science.[6]

He was Dean from 1986–1991, and was responsible for establishing multiple interdisciplinary and/or inter-institutional centers and programs in academic disciplines as material science, opto-electronics, earthquake engineering, surface engineered materials, discrete mathematics for computer science, and plasma etching.[5]

After finishing his tenure as Dean, he was an NEC C&C visiting professor at the RCAST (Research Center for Advanced Science and Technology), the University of Tokyo (1991–1992).[6] Since the fall of 1992 until June 2008, he assumed a full-time research and teaching position at Princeton University's Department of Electrical Engineering.[5]

He was a BC ASI Visiting Fellow at the University of Victoria in Canada from 1998–1999.[6]

He retired from Princeton University in June 2008.[12] In the fall semesters of 2012-13, and 2013-14, however, Kobayashi was a visiting lecturer at Princeton University and taught a graduate course on "ELE 526: Random processes in information systems".[13]

He was a distinguished researcher (part-time) at the National Institute of Information and communications technology (NICT) of Japan in 2008–2016.

Since 2016 he was challenging the Riemann hypothesis.[14][15][16] Since 2020, he was actively pursuing a new stochastic model of an infectious disease.[17] [18][19][20][21]
