I am a physician by trade. After a career in the pharmeceutical world I decided to take it a bit slower and do things I like. Other than my hobbies that involves grassroots medicine in S.E.&P Asia. I have built low income cow dung bio-reactors, solar lamps and family fish ponds as well as houses out of every kind of thinkable material. Instructables is an endless source of inspiration for my projects.
