He is Kenya's first cardiothoracic surgeon and a professor of thoracic and cardiovascular surgery at the University of Nairobi.
During his tenure, he successfully steered the faculty towards cost-sharing through its most difficult period for both staff and students.
Odhiambo has campaigned widely against substance use and is at the forefront in the fight for the liberation of tobacco farmers in East Africa.
He is involved in many community projects in his home village of Kanyaluo, found in Rachuonyo District in Western Kenya's Homa Bay County.
The tragedy, which exposed corruption in the Kenya Police at that time, received wide media coverage and was a major source of motivation for Odhiambo's interest in, and consequent campaigns toward, the efficiency and effectiveness of the Kenya Police.
