Doctor of Philosophy

General Information

The Ph.D. degree program in Mathematics and Statistics includes the following concentrations

Doctor of Philosophy in Mathematics and Statistics

  • Concentration in Mathematics
  • Concentration in Bioinformatics
  • Concentration in Biostatistics

These concentrations address the critical need for mathematics faculty and the need for highly trained specialists in the areas of bioinformatics and biostatistics. The concentrations in bioinformatics and biostatistics will graduate strong bioinformaticians and biostatisticians with a broad background in applied areas for direct placement in business, industry, governmental institutions and research universities. The mathematics concentration will graduate mathematicians with broad knowledge of core areas of pure and applied mathematics.
