Radha Sinha (Radharaman Prasad Sinha) was born and educated in Bihar ( India ). After receiving a Masters degree in Economics from Patna University , he became a lecturer in Economics at Ranchi University. He then traveled to the UK for further post-graduate education and received a Ph.D. in Economics from Manchester University in 1958. He returned to his old job at Ranchi University the same year.

In 1963 Radha Sinha moved to the U.K., first working as a lecturer in Manchester University before joining Glasgow University. He taught and conducted research there for twenty five years and retired as Professor of Political Economy and Director of the Centre for Development Studies. Soon thereafter he was invited to take up a Chair in International Economics at Sophia University, Tokyo ( Japan ) where he worked for ten years before retiring in 1999.

Radha Sinha has been committed to raising the standard of efficiency of civil servants in developing countries for which he organized and co-directed Commonwealth Secretariat-funded short-term training programs in developing countries. The programs in India were organized in cooperation with Orissa University and the Institute of Management, Ahmedabad.

During his tenure at Sophia University, for five years, he was also the Director of the Advanced Development Management Program (ADMP), a program funded by Foundation for Advanced Studies on International Development (FASID).

At various short periods in his teaching career, Radha Sinha has also been a visiting professor or a visiting research fellow at various institutions in Australia, Denmark, Israel, New Zealand, Sweden and the United States.

His long-term projections on “The demand for and supply of food in India for 1975”, which he had completed in 1958, brought him to the notice of senior officials of the Statistics Division of the Food and Agriculture Organization (FAO) in Rome. His association as a consultant with the FAO lasted for over a decade, with some intervening interruptions. In this capacity he did some seminal work on the world food problem, highlighting the relationship between poverty and food, poverty and famine deaths as well as the problems associated with landlessness. He also acted as a consultant to the Commonwealth Secretariat in London and authored a two-volume study on Commonwealth agriculture.

Radha Sinha's other important contribution has been the directing of the modeling of income distribution for India, a project funded by the Overseas Development Administration of the British Government; the research was conducted by a team of scholars from Glasgow University, Institute of Growth, Delhi University, and Queen Elizabeth House, Oxford University.

Radha Sinha has also made some important contributions towards the understanding the processes of economic development in China and Japan.

Most recently Radha Sinha spent time as honorary researcher with the Congressional Research Service, U.S. Library of Congress in Washington D.C. During his tenure he authored three reports with Dick Nanto on Chinese economic issues.

Radha Sinha has written extensively on issues connected with food problems, landlessness, income distribution as well as on development issues related to China, India and Japan.
