Data Science

Program Strengths

Students completing the Ph.D. in Data Science will demonstrate competency in the core concepts and techniques of data science, which come from both computer science and statistics. At BGSU, students will develop appropriate techniques to analyze structured, unstructured, or dynamic datasets, understand the principles of analytical methods, and articulate the strengths and limitations of analytical methods. Students will learn the skills needed to communicate effectively with technical and non-technical audiences. The program is designed to identify and respond to ethical concerns with the provenance and use of data while developing new techniques for the analysis of complex datasets.

Why a Doctorate in Data Science?

  • Shortage of skilled staff will persist. In the U.S. alone, there will be 181,000 deep analytics roles in 2018 and five times that many positions requiring related skills in data management and interpretation
  • Over the next five years, spending on cloud-based Big Data and analytics solutions will grow three times faster than spending for on-premise solutions
  • Adoption of technology to continuously analyze streams of events will accelerate as it is applied to Internet of Things (IoT) analytics

Admission Criteria

  • Three letters of recommendation
  • GRE/GMAT test scores
  • Minimum 3.0 GPA on 4.0 scale
  • TOEFL/IELTS scores for international students

All applicants will apply directly to the Ph.D. program whether or not they have earned a master's degree. Upon review by the admissions committee, students who do not have an earned master's degree in data science, statistics, applied statistics, computer science, mathematics, or a closely related field, will be enrolled in the 90 credit pathway and will first complete the 30 credit MS in Data Science program before entering the 60 credit post-master Ph.D. program. Others needing additional prerequisite coursework may be admitted to the 60 credit pathway with additional credit requirements.


Successful candidates for the M.S. or Ph.D. in Data Science must demonstrate proficiency through coursework or clear professional experience in the following areas:
