About Me

Hans de Ruiter

I am an electrical & electronic engineer from New Zealand, with a Ph.D. in applied science/engineering from the University of Toronto, Ontario, Canada. As can be expected, many of my interests are computer and engineering related. However, I also enjoy hiking and the outdoors. Playing violin and piano are also spare time hobbies of mine.
