Singapore, officially the Republic of Singapore, is a Southeast Asian island city-state off the southern tip of the Malay Peninsula, 137 kilometers north of the equator. A number of foreign universities, business schools and specialised institutes have also setup their Asian campuses in Singapore. Singapore is one of the safest major cities in the world by virtually any measure.

A PhD, or Doctorate of Philosophy, is the highest degree awarded in many academic fields. Generally requiring a research project and dissertation, as well as several years of study, a doctorate degree qualifies the holder as an expert in a chosen field.
