Carlo Heinrich Séquin (born October 30, 1941) is a professor of Computer Science at the University of California, Berkeley in the United States.

[1] Having received his doctorate, Séquin went on to work at the Institute of Applied Physics in Basel on the interface physics of MOS transistors and problems of applied electronics in the field of cybernetic models.

From 1970 to 1976 Séquin worked at Bell Telephone Laboratories in New Jersey on the design and investigation of charge-coupled devices for imaging and signal processing applications.

While at Bell Telephone Laboratories he was introduced to computer graphics in lectures given by Ken Knowlton.

In 1977 Séquin joined the Faculty in the Electrical Engineering and Computer Science Department (EECS) at Berkeley where he introduced the concept of RISC processors with David A. Patterson in the early 1980s.
