Selection and Type of PhD Dissertations
Choosing a topic for your dissertation must be a carefully considered process. This is a crucial component of your doctoral studies that takes months to complete, and it requires deep immersion into the subject matter.
Based on feedback from program graduates and current students, the selection of dissertation topics is founded on five primary considerations:
- A newly discovered topic of interest drawn from a PhD class or lesson
- Corporate interest, particularly if the student’s employer is funding tuition
- Faculty interest
- Personal interest
- Urgency, based on the availability to certain data or information to the student and limited time or resources to complete a dissertation
Most dissertations in the field of safety science are mixed method studies, a combination of quantitative and qualitative research. These dissertations are founded on survey results, physical experiments, and epidemiological studies. To date, graduates of ÑÇÉ«Ó°¿â’s PhD in Safety Sciences program have most frequently conducted surveys for their dissertation, followed by physical experiments, and then epidemiological studies.
