About
I am a Mechanical Engineer teaching and researching in the field of renewable energy technologies and systems. I did my PhD (Dr. techn.) at Vienna University of Technology, Austria. I am currently a researcher at Department of Electric Energy, NTNU. Previously I have been Asociate Professor at Mekelle University, Ethiopia.
I am currently working on the research topic solar energy in Nordic climate conditions associated with Team Solar at NTNU.
Attached my brief CV.
