MICKYDAWSONAs he tells it, his Dad’s choice for secondary school was either of St. Augustine’s Secondary or Mfantsipim Schools, but Mickey had a better choice. Thus, on Wednesday September 25, 1974, Mr. Mickey Otabil Dawson-Annan (fka Michael Baidoo-Otabil) entered GSTS as a resident of Dodoo House (House 6) until June 1981.

He completed his O/level (1979) and A/Level (1981). Mickey was an excellent “da-me” (draughts) player, and represented his house. He also played Scrabble and was a member of the Chess Club.

In 1987, Mickey graduated from KNUST with a BS in Geological Engineering. At KNUST, was elected Queens Hall Secretary and SRC Member (1985).

A year later he was appointed Queens Hall NUGS Representative and served on local NUGS Board. After graduation, taught Mathematics at Apam Secondary School for his National Service and then worked for the Drilling Unit of Ghana Water and Sewerage Company as Trainee Hydrogeologist. In 1989, he was appointed Assistant Hydrogeologist/Geophysicist in the Unit and worked on borehole drilling projects across Ghana but mainly in the Northern and Upper Regions of the country.

He followed this up with an MSc. in Computer Systems Engineering from the Technical University of Denmark. After rediscovering his passion for Statistics, he obtained a second MSc in Statistics from the University of Calgary, Calgary, Canada and went on to obtain a PhD in Biostatistics from the same university in 2008.

Joseph credits his love for humanitarian engagements and tolerance to his 5 years of study at GSTS. During that time, he engaged and lived with people from all walks of life. For example, he worked on school projects and made lifetime friends with students from across Ghana and Africa, including students from war-ravaged countries like Liberia and Namibia. Joseph also gives a lot of credit to GSTS for his love for Statistics because GSTS provided him with a strong foundation in Mathematics.

Dr. Amuah is a member of the Board of Trustees of GSTS Alumni Association of North America. At GSTS, Dr. Amuah was a member of Weston House (House 3) and was the Welfare Monitor of the house during his final year of study.
