CURRICULUM VITAE of Ibrahim A. Eltayeb
Ibrahim was educated in government schools in Sudan. He was awarded a scholarship to
read Mathematics in the United Kingdom. He graduated from the University of London
in August 1968 and proceeded to read for PhD at the University of Newcastle-upon-Tyne
under the supervision of Professor P.H. Roberts, FRS. He returned to Sudan and took up
the post of lecturer in mathematics at the University of Khartoum in April 1972. He was
subsequently promoted to Senior lecturer, Reader and then to Full Professor in 1980. He
was Dean of the newly established School of mathematical Sciences during the period
1981- 84.
He joined the newly established Sultan Qaboos University in August 1986. He was Head
of the Department of Mathematics and computing, which later became the department of
mathematics and statistics. Under his chairmanship during the period 1988-1998, degrees
in Mathematics, Statistics and Computer Science as well as Master's degrees in Applied
Mathematics, Pure Mathematics and Statistics were established for the first time in
Oman.
The subject of his PhD thesis was thermal convection in rotating magnetic fluids. He has
over the years extended his research interests to the mathematical modelling of
geophysical, environmental and industrial problems. One of the main areas of interest is
that of dynamo theory which relates to the study of the non-linear partial differential
equations governing the maintenance of the geomagnetic field and related problems.
Another area of main interest is that of the transport of sand and dust which relates to
desertification and industrial pollution. Recently he has developed an interest in the
dynamics of directional solidification of fluid alloys and the flow of water in karstic
aquifers.
