Doctorate Studies in Life Sciences in China
The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
In regards to the study of biological & life sciences, students may focus on one aspect of natural science or study how they work together, such as the environment and human health or biology and geology.
