Courses on Environmental Health

Doctoral programs in Environmental Health Sciences are designed to prepare students for technical, professional and supervisory positions and careers in academic institutions, public agencies and industry.

 

The curriculum emphasizes the application of classical biological, physical and medical sciences to help solve environmental and public health problems.

 

* Those applying for PhD in Environmental Health need to have completed a Master’s degree in Natural Sciences.
