General Bio
Name:
Dr Raymond Paul Agwunobi UnammaB.Sc. (Hon), M.Sc., Ph.D. About Me:
My first exposure to the use of the Computer was during a two months (June – July 1991) Computer Literacy Course at the World Bank Resident Mission, Lagos. The course covered basic Computer Appreciation and Literacy Training for World Bank Principal Staff. A follow up four weeks Advanced Computer Course, in December 1992, at the World Bank Washington D.C. USA, which covered Computer Training on Word Processing and Spread Sheet using Microsoft Word and Excel and System Maintenance. This training was organized at the World Bank HQ to expose senior staff to the use of Windows Programs and modern computer systems maintenance. Several other trainings and tours at the World Bank exposed me to various ways of leading people to achieve common objectives, exposure to better ways of preparing and presenting reports and understanding the systems that enabled me to restructure the Nigerian and other West African extension systems.
