Amartya Sen, (born November 3, 1933, Santiniketan, India), Indian economist who was awarded the 1998 Nobel Prize in Economic Sciences for his contributions to welfare economics and social choice theory and for his interest in the problems of society’s poorest members. Sen was best known for his work on the causes of famine, which led to the development of practical solutions for preventing or limiting the effects of real or perceived shortages of food.

Sen was educated at Presidency College in Calcutta (now Kolkata). He went on to study at Trinity College, Cambridge, where he received a B.A. (1955), an M.A. (1959), and a Ph.D. (1959). He taught economics at a number of universities in India and England, including the Universities of Jadavpur (1956–58) and Delhi (1963–71), the London School of Economics, the University of London (1971–77), and the University of Oxford (1977–88), before moving to Harvard University (1988–98), where he was professor of economics and philosophy. In 1998 he was appointed master of Trinity College, Cambridge—a position he held until 2004, when he returned to Harvard as Lamont University Professor.
