What can you do with a PhD in Public Health?

Studying public health is a wonderful choice for those who wish to dedicate their career to advancing healthcare delivery & practices and improving the health and wellbeing of the public. This can take many forms – from studying diseases in a laboratory to using statistical analysis to develop better distribution of medication.

A PhD programme in Public Health equips students with knowledge in environmental health, statistical analysis, data collection, ethics, research, report writing, and environmental law amongst others. This makes Public Health doctorates suitable for a wide range of careers in the field, both academic and non-academic.

A PhD degree also offers the student the opportunity to specialize their study in a particular area of interest. Generally, the principal research areas that contribute to the subject include:

 

Epidemiology

The World Health Organization defines epidemiology as “the study of the distribution and determinants of health-related states or events (including disease), and the application of this study to the control of diseases and other health problems.”

Public Health doctorates can use their knowledge of diseases and health events to transition into a career in epidemiology. Typical employers include public health departments (for example the NHS), health institutions (for example WHO) and private companies (for example companies developing medication).

The world is in the middle of a global pandemic, as the coronavirus continues to spread rapidly across the globe. It is epidemiologists who are leading the efforts to monitor the transmission of virus and study the disease (COVID-19) it causes. Using this as an example, typical responsibilities of an epidemiologist include studying infectious diseases, educating governments, and advising policy makers.

Behavioural Science

Behavioural science is the scientific study of human and animal behaviour. In the context of public health, this relates to the study of the human behaviours and social constructs, identify links with public health issues.

For example, obesity is often caused by a poor diet and lifestyle choices more than it is by medicinal/genetic factors. There are often social and behaviour factors which influence diet and lifestyle choices. A career in behaviour science would look to establish relationships between the two, and whether we as a society can take preventative action.

According to a Press release by Public Health England, a quarter of cardiovascular disease deaths are in people under the age of 75, with 80% of these preventable if people made lifestyle and behaviour changes to improve their heart health. This highlights the influence behavioural scientists can make in society, by educating the public and advising the government and policy makers to enforce new policies which aim to address social issues and change behaviour to improve public health.

 

Biostatistics & Health Informatics

Biostatisticians and health informatics specialists analyse health data, applying statistical models to interpret the data and drawing conclusions to address public health and medicinal issues.

The nature of this role lends itself to many departments within public health. For example, typical employers range from Food and Drug Administration clinics, research centres looking at genomes, local governments, and other public health organisations.

 

Environmental Health Sciences

Environmental health science is the study of all aspects of the natural and built environment which influence human health. For example air pollution, soil contamination, climate change, food hygiene, drinking water contamination. Environmental health scientists aim to reduce the environmental factors which adversely affect human health. Much like other public health professionals, they do this by carrying out research, helping governments develop and enforce policies & laws, and educating the public.

Examples of typical roles that public health PhD holders transition into include: air pollution analysts, health inspectors, toxicologists, and health, safety and environment advisors.

Health Policy and Management

Health policy and management professionals use their knowledge to improve the effectiveness of healthcare delivery in terms of finances, management, logistics, and quality.

Such a career would involve management duties such as managing teams, delegating tasks, monitoring project progress, managing budgets and identifying opportunities to improve performance.

Typical employers include research and development companies, government institutions and NGOs.

 

Education

Typically, people think education relates to teaching at a school or university. However, with a PhD in public health you can work with public health organisations, governments and NGOs, to educate about health and safety issues. With this career you could run education programmes or produce informative brochures and posters to encourage a healthier lifestyle (e.g. eating a balanced diet), stress the importance of health and safety practices (e.g. look both ways before crossing at a road) and more.

 

Higher education teaching

One of the biggest advantages of holding a PhD degree is the opportunity it provides for teaching at Universities. A PhD is typically a requirement for a teaching role at universities. University lecturers have much more freedom in the contents of their course than lower education teachers, which allows you to focus on your chosen speciality. Universities often offer their doctorates part time teaching positions as a way of assisting in the transition from student to teacher.

It is important to note that an educational role in higher education is not just limited to lecturing at a university, but also includes tutoring and researching.

Other roles

A PhD degree in public health can lead to a career in nutrition and diet, which can vary from research into the nutritional content of foods, to being dietician who creates meal plans for clients. Other public health jobs include involvement in global health, genetics and maternal & child health.

 

Skills for your CV

It is important to remember that whilst most Public Health doctorates pursue a career in the field, holding a PhD in the subject gives you several skills and attributes which make you desirable to a wide range of employers. You must be able to recognise these skills when preparing your CV and job applications.

Examples of skills you will learn as a student with a Public Health background include:

  • An understanding of the public health issues faced across the world
  • And understanding of the social and environmental factors which can influence health
  • An understanding and application of statistical methods and analytical techniques
  • Use the above knowledge to become more influential in society and relate your knowledge to public policy

 

In addition to the above, having a PhD also equips you with a number of transferable skills. These are skills which are vital in the professional working environment and can be used in any sector. Examples include communication, team working, work ethic, time management, problem solving and the ability to carry out independent research.
