[1] Mathayo (formerly known as David Msuya) graduated from Sokoine University in Morogoro with a Bachelor of Veterinary Medicine in 1997.
While in Botswana he "won" an election as an MP of West Same constituent back in Tanzania and got picked to be a deputy minister in Trade and Industry.
His selection was the epitome of president Kikwete's new leadership style which disregarded age as a factor and valued education and talent.
Mathayo's qualifications have been a subject of debate in the public since his selection into his current ministerial position.
Many people who know Mathayo personally including his Sokoine University lecturers believe that his postgraduate qualifications, especially the Ph.D, are unlikely to be genuine.
