Abebe R. Tufa (Ethiopia) received one of the three IMU Breakout Graduate Fellowships awarded in 2016 to complete a research that was already in progress. He has obtained his Ph. D. in June 2018 with a thesis on Approximating Solutions of Fixed Point, Variational Inequality and Hammerstein Type Equation Problems, developed in the Department of Mathematics of the University of Botswana, Gaborone, supervised by Prof. Habtu Zegeye Hailu (Botswana International University of Science and Technology) and co-supervised by Dr. Mosalagae Thuto (University of Botswana). After a four years period of study in Botswana he is now back at his home University at Bahir Dar in Ethiopia where he started working as Assistant Professor.
