Biography

I am Dr Njagi John Nguu , PhD holder in Physics, I have taught University Physics courses for over 15 years. My experience has leveraged my expertise in lecturing, curriculum development, academic journal reviewing, lesson preparation, assessment and developing proposals for research funding. Moreover, I also possess good communication skills which help in disseminating knowledge in conferences and in publications. I have the ability to work independently and as a part of a team.
