Biografi/ Biography :
Dr. Razik Ridzuan Mohd Tajuddin is a Senior Lecturer in the Department of Mathematical Sciences, Faculty of Science and Technology, Universiti Kebangsaan Malaysia since December 2022. Interested in theoretical statistics with applications to actuarial science which includes GLM and inflated models, as well as quantitative criminology. Current research focus is on the development of heatmaps/hotspots from narcotics abuse crimes in Malaysia, in collaboration with Jabatan Siasatan Jenayah Narkotik, Polis DiRaja Malaysia.
