Biografi/ Biography :
Ishak Hashim was born in Melaka, Malaysia, in 1969. He obtained the degree of Bachelor of Science (Mathematics) from The Ohio State University, US, in June 1992. He joined Universiti Kebangsaan Malaysia (UKM) as a Mathematics Tutor in March 1993. He obtained the degree of Master of Science in the Mathematics of Nonlinear Models from Heriot-Watt University, UK, in November 1994. His degree of Doctor of Philosophy (Mathematics) was obtained in March 1998 from the University of Strathclyde, UK, under the supervision of Professor S.K. Wilson in Fluid Mechanics. Ishak has been a Professor at the School of Mathematical Sciences, Faculty of Science and Technology, UKM, since August 2008. His research interests in applied mathematics include convective instabilities in fluid flows, boundary layers, computational fluid dynamics and analytical/numeric-analytic methods for nonlinear equations.
