It also focuses on finding ways to improve experimental design and create new measurement tools for science, medicine and engineering applications.

  • Biochemistry

Biochemistry explores the chemical processes present within and linked to living organisms. It is a sub-discipline of both chemistry and biology and can be used to conduct research in areas such as protein structure, metabolic pathways and enzymology. The skills gained while pursuing a PhD in biochemistry can be applied in agriculture to investigate soil and fertilisers and improve crop cultivation and storage.

  • Environmental chemistry

Environmental chemistry involves the study of chemical and biochemical occurrences that can be observed in natural places. It allows researchers to study the sources, reactions and effects of different chemicals in air, soil and water. While environmental chemistry greatly depends on analytical chemistry, it also involves the study of the atmosphere and other elements present in the environment.

  • Medicinal chemistry

Medicinal or pharmaceutical chemistry is an interdisciplinary field that involves the study of chemistry along with medical or pharmacy. It focuses more on the design and development of pharmaceutical drugs for therapeutic use. A PhD in medicinal chemistry will teach you the skills needed to identify organic chemical compounds that can be used for treating various health concerns. 

Some of the common branches of chemistry are listed above. Several universities offer interdisciplinary courses that allow students to combine chemistry with other subject areas. Based on your goals, you can select a specialisation that aligns with your preferences.
