Staff Profiles

• BEd (Mathematics), Bahir Dar University, Ethiopia, 2004.
• MSc (Mathematics), Addis Ababa University, Ethiopia, 2008.
• PhD ( Mathematics, Analysis), University of Botswana, Botswana, 2017

Dr. Abebe Tufa obtained a Bachelor Degree in Mathematics from Bahir Dar University (Ethiopia) in 2004, where due to his excellent academic track was appointed immediately afterwards as Graduate Assistant in the department of mathematics. His university has sponsored his formation in Addis Ababa University to obtain MSc in 2008. Afterwards, he has been teaching as Lecturer again at Bahir Dar University until he joined University of Botswana in February 2014 for PhD study sponsored by Simon's Foundation. The last two years of his study was also sponsored by the International Mathematics Union (IMU) Breakout Graduate Fellowship: A competitive fellowship offered a limited number of grants for excellent PhD students from Developing countries. He obtained his PhD degree in mathematics from UB in 2017 and rejoined Bahir Dar University as Assistant Professor.

 Dr. Tufa joined University of Botswana as a lecturer in January 2019. Currently, he is one of the academic staffs at UB who is actively engaging himself in the research activities and community services besides teaching in the department of Mathematics. He is also a reviewer in several international mathematics journals such as Afrika Matematika (Springer), Advances in Mathematical Physics (Hindawi) and Mediterranean Journal of Mathematics (Springer).
