He is best known for his work in the field of ionizing radiation response on Bipolar junction transistor (BJT) and Enhanced Low Dose Rate Sensitivity in BJT.

Intel's Ted Hoff was assigned to studying Busicom's design, and came up with a much more elegant, 4 ICs architecture centered on what was to become the 4004 microprocessor surrounded by a mixture of 3 different ICs containing ROM, shift registers, input/output ports and RAM—Intel's first product (1969) was the 3101 Schottky TTL bipolar 64-bit SRAM.
Among the most important of his contributions are the Gummel–Poon model which made accurate simulation of bipolar transisors possible and which was central to the development of the SPICE program; Gummel's method, used to solve the equations for the detailed behavior of individual bipolar transistors,; and the Gummel plot, used to characterize bipolar transistors.
The microprocessor was notable for its high clock frequency (for the time, circa 1997) in the range of 400 to 533 MHz, its use of bipolar transistors for logic and CMOS circuits for memory, and its failure to see use in an Apple Macintosh, the opposite of what industry observers such as Microprocessor Report expected.
