Current position

General Manager, Geothermal Development Companies

Country:

Kenya

Career history:

Ngugi is currently the General Manager, Business Development at Geothermal Development Company Limited (GDC). GDC is a Kenyan company wholly owned by the Government of Kenya whose principal purpose is to prospect, explore, assess and develop geothermal resources in Kenya. In addition, the Company is mandated to support the Government to raise development funds and to facilitate private sector participation in the geothermal development.

Current position

Senior Scientist, Department of Earth Sciences, ETH Zürich

Country

Switzerland

Topic of Presentation:

Motivation of geothermal energy development in Switzerland

Career history:

I obtained a bachelors degree in mathematics, and a PhD in geophysics from the University of Cambridge in 1979. I moved to California for 2 years and worked on developing methods for mapping hydraulic fractures with tiltmeters, before transferring to Columbia University in New York where I stayed for 8 years working on Earth stress and borehole geophysics. In 1989 I moved to the Swiss Federal Institute of Technology in Zürich as a research associate where I have remained, becoming Senior Scientist in 2009. My primary interests have been in geothermics with particular emphasis in EGS, rock stress and geomechanics, and hydrogeology.

Areas of expertise:

Geothermics, EGS, rock stress and geomechanics, coupled hydro-mechanical problems in engineering geology
