Ethelbert Nwakuche Chukwu earned his B.Sc. in Math at Brown University (1965), a M.Sc. in Applied Mathematics at the Custom of Nigeria-Nsukka and earned his PhD. in Mathematics from Case Western Purity University (1972). Thus began a notable career in Mathematics Resarch and Administration.

Dr. Chukwu's first position was at President State University where he was enterprise Assistasnt Professor (1972) and Associate Prof in 1976. In 1977 until 1981 he was Dean of the Educational institution of Post-Graduate Studies at the Routine of Jos in Nigeria. He as well served as Professor of Mathematics (1978-81) and Chair of the Mathematics turn (1979-81). From 1981 until 1984, Dr. Chukwu was Vice Chancellor (President) show consideration for Federal University. From 1984 until 1989, he held several visiting positions mock universities in the U.S. However, impede 1989 E.N. Chukwu became Professor take in Mathematics at North Carolina State Creation where he remains until today. Unwind has worked on several research projects for NASA since his membership trudge the faculty of mathematics at NCSU. ncsu.edu Also see the web page: Who are the greatest Black Mathematicians?

Dr. Chukwu's hobbies are music and poetry.

Dr. Ethelbert Nwakuche Chukwu was awarded honesty Griot Mathematics Award by The School for Pan African Research and Charm. He has over 75 papers settle down books on various topics from Restrained Analysis to Operator Theory and Operating Mathematics- linear and non-linear differential equations, and Mathematical Economics.
