Daniel Shawul Abdi,
an Ethiopian computer scientist and civil engineer with focus on wind engineering and computational wind / structural engineering, actually postdoc at Naval Postgraduate School, Monterey, California. He holds a B.Sc. from Addis Ababa University, a M.Sc. from Indian Institute of Technology, and a Ph.D. from Western University in 2013, and was also affiliated with Florida International University and its Wall of Wind testing facility for hurricane simulations. His research includes high performance computing, and the use of artificial neural networks for boundary layer wind tunnel (BLWT) profile development [2]. During his Ph.D., he developed a finite-volume code for the simulation of wind flow over complex terrain. Recently, he has extended the code to use high-order Discontinuous Galerkin methods [3].
As computer chess and games programmer, Daniel is author of the chess engines DanChess, Scorpio with its own open source endgame bitbases (EGBBs) format, and the general game playing engine Nebiyu based on Scorpio, able to play Chess variants, Checkers, Reversi, Go and Amazons [4].
