Doctor of Philosophy (PhD)(Mathematics)
Ph. D. in Mathematics, Faculty of Science (FOS), is a programme that fosters pure and applied research in different branches of Mathematics. The Mathematics Group offers postgraduate research opportunities in a number of areas of Pure and Applied Mathematics, Statistics, Operations Research and Financial Mathematics. A particular focus initiative of the Group is the recentlyestablished Mathematical Modelling and Simulation Cluster, which aims to pursue research in areas such as mathematical epidemiology, inventory analysis, hydrology, crop production and the properties of nanoparticles. One important resource available to the Modelling and Simulation Cluster is UBD’s BlueGene supercomputer, which is currently the only supercomputer in South East Asia. The Programme is designed for qualified individuals, who wish to acquire advanced knowledge, as well as analytical and research skills in Pure and Applied Mathematics. Students interested in starting a Masters or Doctoral degree in Mathematics at UBD should in the first instance contact one or more of the staff members, and liaise with them to design a suitable research project.
Programme Details
Aims and Scope
The PhD Programme in Mathematics aims to make researchers and scientists with high level specialised skills in order to cope with the increased demands of governments, industries, banks, hospitals etc. The scope of the Programme is to provide students the necessary specific scientific information, as well as to train them to develop their skills and analytical capabilities.
Structure
Students conduct research on an approved research topic, under the supervision of one or more staff members. Upon completion of their research, they submit a Thesis, which normally does not exceed 100,000 words.
Assessment
 Compulsory modules SR5101. These are modules that all postgraduate students must read and pass to satisfy their graduation requirement.
 Assessment includes examination of the thesis by internal and external examiners. As stipulated in the relevant UBD regulations the examiners may subject a candidate to an oral examination or any other test they think necessary to assess the acceptability of the thesis. Periodic assessment of the progress of the candidate is carried out as stipulated in the relevant UBD regulations.
