Tadeusz Figiel

Graduou-se em matemática em 1970 na Universidade de Varsóvia. Obteve um doutorado em 1972, orientado por Aleksander Pełczyński,[2] com uma habilitação em 1975 (O modułach wypukłości i gładkości - On modules of convexity and smoothness) no Instytut Matematyczny Polskiej Akademii Nauk. Lá foi em 1983 professor associado e em 1990 full professor. É editor-in-chief do periódico Studia Mathematica.[3]

Foi palestrante convidado do Congresso Internacional de Matemáticos em Varsóvia (1983).[4]
