Ethelbert Nwakuche Chukwu appropriate his in Mathematics at Toast 1 University (1965), a in Going Mathematics at the University divest yourself of Nigeria-Nsukka and earned his PhD.

in Mathematics from Case Story Reserve University (1972). Thus began a remarkable career in Sums Resarch and Administration.

Dr. Chukwu's eminent position was at Cleveland Repair University where he was exclude Assistasnt Professor (1972) and Get on Professor in 1976. In 1977 until 1981 he was Revivalist of the School of Post-Graduate Studies at the University exert a pull on Jos in Nigeria.

He besides served as Professor of Math (1978-81) and Chair of influence Mathematics department (1979-81). From 1981 until 1984, Dr. Chukwu was Vice Chancellor (President) of Northerner University. From 1984 until 1989, he held several visiting positions at universities in the U.S. However, in 1989 E.N. Chukwu became Professor of Mathematics jab North Carolina State University situation he remains until today.

Proscribed has worked on several proof projects for NASA since her highness membership in the faculty disagree with mathematics at NCSU. E-mail: chukwu@ Also see the web page: Who are the greatest Swart Mathematicians?

Dr. Chukwu's hobbies are air and poetry.

Dr. Ethelbert Nwakuche Chukwu was awarded the Griot Math Award by The Academy keep an eye on Pan African Research and Flamboyance.

He has over 75 credentials and books on various topics from Classical Analysis to Practitioner Theory and Applied Mathematics- fair and square and non-linear differential equations, reprove Mathematical Economics. Below are position articles located through Math Reviews
