Summary

Is a lecturer of Physics and Physical sciences in the Department of Science and Engineering of Daystar University. He is currently pursuing doctoral studies in Physics (condensed matter), at the University of Nairobi. Mr. John Nguu has taught University Physics courses for over ten years. John served as the head of Department of Science, from 2007- to 2009 within which time he participated in developing a B.Sc. Physics curriculum for Daystar University.

 

Mr. Nguu has actively been involved in research. His research interests lies in the development and implementation of renewable energy technologies for solar and biogas energy resources. Research topics include; energy conversion technology, modification of materials for energy conversion, powder coatings and characterization, electrophoretic deposition of thin films, developing composite electrodes for dye-sensitized solar cells and solar panels. In 2010, John secured funding of $ 2,000 from Daystar University for research on biogas generation. His current (2013-present) publications include 6 papers in peer reviewed journals.
