# Michael Antonio Savageau

Michael A. Savageau (born 3 December 1940) is a Distinguished Professor in the Departments of Microbiology & Molecular Genetics and Biomedical Engineering at The University of California, Davis. He was named Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2013 for application of systems engineering concepts to molecular biology.

## Early life and education

Michael Antonio Savageau one of seven children, was born in Fargo, North Dakota on December 3, 1940. His father was a barber and his mother was a schoolteacher. He was an avid hockey and tennis player through high school, and he has credited sports with teaching him valuable life and professional skills. He struggled with undiagnosed dyslexia throughout his entire academic career, but he developed compensatory strategies. For example, he was unable to take notes in lecture classes, so he developed formidable concentration and memory skills. His dyslexia sparked his interest in mathematics and he excelled in those classes. Savageau graduated from Fargo Central High School in 1958 and went on to earn his Bachelor of Science degree in Engineering from the University of Minnesota in 1962, and a Master of Science degree from the University of Iowa in 1963. He was accepted into the Ph.D. program in Electrical Engineering at Stanford University in 1963, and it was there that he began to develop his interest in applying engineering principles and methodologies to biological systems. Savageau was a postdoctoral fellow at both The University of California, Los Angeles (1967 - 1968, in the laboratory of Prof. Isaac Harary) and Stanford University (1968 - 1970, in the laboratory of Prof. J.P. Steward) prior to joining the faculty at The University of Michigan in 1970. He initiated Michigan’s interdisciplinary training program in Cellular Biotechnology and its interdisciplinary Bioinformatics Program. He also chaired the Department of Microbiology & Immunology from 1979 to 1985 and from 1992 to 2002 and was named the Nicolas Rashevsky Distinguished University Professor in 2002. After moving to the University of California, Davis in 2003 he chaired the Department of Biomedical Engineering from 2005 to 2008

## Personal life

Savageau met fellow student Ann Birky, (currently Ann Savageau, an artist and professor of art and design), at Stanford and they were married in 1967. They raised their family in Ann Arbor, Michigan, where both of them held faculty positions at The University of Michigan. They had three children, Mark, Patrick and Elisa, all of whom have preceded them in death. They are helping to raise their grandchildren in Davis, California.
