The Division of Environmental Health Sciences provides a cornerstone to public health through multidisciplinary research, training, and practice that is focused on chemical, physical, and biological agents in the environment that influence human health. Its scope is broad, encompassing both the environmental and biological processes and mechanisms underlying human disease and prevention.
Research in environmental health seeks to understand the effects of external influences on our health. Much of our faculty's scholarly work is done in collaboration across the university and with other institutions. Research and other funded projects in our division include:
- Chemical properties in berries that may prevent oral cancer
- Safety of Lake Erie water for recreation and as a source of drinking water
- Effects of automobile traffic on human health
- Ohio Public Health Training Center
- Effects of air pollution reduction in Beijing during the Summer Olympics
The PhD degree requires a significant program of study and research that qualifies the recipient to work independently and contribute to the advancement of the field of knowledge. The emphasis is on mastery of the field and particularly on the acquisition of research skills as a basis for original work. Students admitted to the PhD degree program are assigned faculty advisors who will provide guidance throughout the program. Students are encouraged to get to know their advisor and meet with him/her at least twice each semester.
Program of Study
The PhD-EHS curriculum requires a minimum total of 90 semester credits or 60 credits beyond a master’s degree. Some of the specified courses may have been included in a prior master’s degree. A maximum of 30 semester credits of master’s degree work may be applied to PhD requirements if approved by the advisor. Requirements include:
1. Major field (24 credits)
2. Research methods (24 credits)
3. Approved electives (6 credits)
4. Minor congnate field (12 credits)
5. Dissertation (24 credits)
For detailed additional information about specific requirements, students are directed to the College of Public Health (CPH) Graduate Student Handbook and to the Ohio State University Graduate School Handbook.
Strong undergraduate education in science (e.g. biology and chemistry) and math is recommended. Admission decisions are made largely based on GPA, GRE scores, recommendations, personal statement and experience. Minimum GPA and GRE are generally 3.0 and 50th percentile on Verbal and Quantitative sections, respectively. The personal statement is reviewed for writing ability and "fit" between the student's interest and motivation in the degree, relative to what the degree will achieve and the capability and interests of the faculty. The stronger the application with respect to these elements (especially GPA and GRE), the more likely it will be to compete for financial support.
