The practice of transforming substances into usable products is called chemical engineering. Studies in this discipline can prepare students for careers in areas such as the chemical, pharmaceutical, energy and petroleum industries.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.

Part time learning allows one to obtain part-time degrees even if one cannot attend school on a full-time basis. One can learn at his or own pace, gradually accumulating credits which count towards final qualification.
