A doctorate in public health will let you develop your voice in academia, and potentially help you to research a public health solution that could inform and improve the lives of many. Doctorates in public health usually last between three and six years.
Choosing to get a PhD in this field could see you rise to the top as an expert in your chosen field, and gain future employment prospects.
If you study your PhD in public health on a full-time basis, you should be able to receive financial assistance.
This will depend on where you wish to study, but most institutions require either an undergraduate degree or graduate certificate in public health or a related degree. Some may accept substantial work experience in public health. You will likely need to outline your proposed thesis as well. Check with your institution to see what is required of you.
