If you really wish to make a difference in the improvement of public health then you can take up masters in public health.
Public health has a long history of implementing policies that improved of the health of people worldwide. Vaccination programmes, family planning or preventive medicine are just a few examples of how public health had a global positive impact. And you can be part of this, too!
Here are the main career options for students who graduate a Master's degree in Public Health:
1. Health informatics specialist
2. Health care administrator
3. Epidemiologist/research analyst
4. Public health project manager
5. Health and safety engineers
Same is for forensic sciences.
However the Scope of forensics in India is shady because the job applications are not openly discussed as that of engineering and medicine.
But, there is always scope when it comes to working in Forensic State Labs, and Central Forensic Labs, IB, CBI, State and Centre Police, Banks, Other Cooperate Institutes, Mental Health Facilities, Consultants, Private Detectives, and, of course, Teaching.
If you aim for excellence in any field, youll create ways for a career by yourself.
Hope this helps!
