I am half academic and half practitioner after 20 years in business and 20 years in Academia. I have a Master in Chemical and Process Engineering and have worked with mainly cement production as process engineer, quality manager, production manager and consultant. About 10 years of my working practice has been carried out in Sub Saharan Africa, notably in Angola, Bening, Congo Brazzaville and Tanzania. My research focuses on sustainable block based building materials with focus on affordability and low carbon footprints. I currently work with contacts in Kenya, Uganda and Tanzania.
