A Ph.D. graduate in nuclear engineering from Hokkaido Imperial University (Japan) and a Fulbright visiting scholar to Georgia Institute of Technology (USA) (department of mechanical engineering). My experience as a researcher and teacher spans more than 25 years in thermo-fluids with different applications in renewable energies (solar, geothermal), power plants, multi-criteria decision analysis, and Nano and microscales heat transfer. I have also been involved with the Pan African University of Water and Energy Sciences (including climate change) (PAUWES) since its establishment as an expert, teacher, and master's thesis supervisor.
