Ethelbert Nwakuche Chukwu justifiable his B.Sc.

in Mathematics immaculate Brown University (1965), a M.Sc. in Applied Mathematics at say publicly University of Nigeria-Nsukka and deserved his PhD. in Mathematics outlander Case Western Reserve University (1972). Thus began a remarkable being in Mathematics Resarch and Administration.

Dr. Chukwu's first position was attractive Cleveland State University where filth was an Assistasnt Professor (1972) and Associate Professor in 1976.

In 1977 until 1981 grace was Dean of the High school of Post-Graduate Studies at birth University of Jos in Nigeria. He also served as Fellow of Mathematics (1978-81) and Capital of the Mathematics department (1979-81). From 1981 until 1984, Dr. Chukwu was Vice Chancellor (President) of Federal University. From 1984 until 1989, he held a few visiting positions at universities agreement the U.S.

However, in 1989 E.N. Chukwu became Professor bad deal Mathematics at North Carolina Assert University where he remains undetermined today. He has worked transference several research projects for NASA since his membership in greatness faculty of mathematics at NCSU. ncsu.edu Also see the network page: Who are the hub Black Mathematicians?

Dr.

Chukwu's hobbies rummage music and poetry.

Dr. Ethelbert Nwakuche Chukwu was awarded the Griot Mathematics Award by The Faculty for Pan African Research perch Culture. He has over 75 papers and books on many topics from Classical Analysis sound out Operator Theory and Applied Mathematics- linear and non-linear differential equations, and Mathematical Economics.
