Program Learning Outcomes
Upon completion of the doctoral degree, students in the Data Science program are expected to be able to:

• Demonstrate competency in the core concepts and techniques of data science, which come from both computer science and statistics.
  
• Demonstrate the ability to use or develop appropriate techniques to analyze structured, unstructured, or dynamic datasets.
  
• Demonstrate an understanding of the principles that underlie analytical methods, to articulate the strengths and limitations of analytical methods, and to defend choices to use some methods over others.
• Demonstrate the ability communicate effectively to technical and non-technical audiences orally, in writing, and with effective visualization.
• Demonstrate the ability to identify and respond to ethical concerns with the provenance and use of data.
  
• Demonstrate the ability to develop new techniques for the analysis of complex datasets or real-time modeling and decision-making, or extend existing techniques to novel and challenging datasets.
  
• Demonstrate the ability to organize data using tools appropriate to the problem, code new techniques in the appropriate computer language, optimize for performance and scalability, and distribute new tools to the data science community in a usable form.
  

Prerequisite to Graduate Work
Prerequisite coursework includes differential, integral, and multivariate calculus, linear algebra, senior-level introduction to probability and statistics, programming skills in high level languages such as C, C++, Java, Python, and understanding of data structures and computer algorithms

Admission Procedure
Applicants must complete the admission process required by the Graduate College that includes submission of the complete online application, all previous college and university official transcripts (a minimum GPA of 3.0 required), GRE General Test or GMAT scores, statement of purpose, resume, three letters of recommendation from faculty or professionals in the field, and, for certain international students, TOEFL or IELTS scores. Applicants should refer to the Graduate Admissions web site for a complete list of admission procedures. 

All students will apply to the PhD program whether or not they have earned a master’s degree.  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 Data Science Master’s program before entering the 60 credit post-master PhD program. Students with an earned master’s degree in data science, statistics, applied statistics, computer science, mathematics, or a related field should have the course background that makes it possible to immediately take PhD-level courses in computer science or statistics.  Others who have been determined by the Committee to need additional prerequisite coursework may be admitted to the 60 credit pathway with additional credit requirements.

Applied Data Science Experience (3 hours) 
DATA 7890 Internship/DATA 7930 Directed Reading: Satisfy this requirement by getting Graduate Coordinator's pre-approval for a data science related internship or professional position, or joining a research group on or off campus, preferably after successfully completing at least 9 credit hours in Data Science. The experience is documented by registering for 3 credit hours of internship, DATA 7890, directed readings credit such as DATA 7930, or similar course.  The final report for these classes must identify and analyze ethical considerations encountered during the experience.  

Elective Courses (21 credit hours):  
Choose 7 additional courses with at least 2 from CS, at least 1 from MATH,  and at least 1 from OR/STAT.

Qualifying Examination: 
Students will take a qualifying examination preferably after the first  academic year of the PhD program (approximately 18 credit hours) in order for the program faculty to evaluate the student’s progress in the different disciplines necessary for the degree. In order to continue in the PhD program, a student must pass the qualifying examination. Students will take and pass one exam in Statistics and one exam in Computer Science. These may consist of two PhD-level exams or one PhD-level exam and one master's-level exam. The choices of the exams are:

Preliminary Examination: 
A student must pass the Qualifying Examination to qualify to take the Preliminary Examination. The Preliminary Examination includes a written and an oral component. This is a research-oriented examination intended to help prepare students to begin their dissertation research. The Preliminary Examination Committee must have representation from at least two of the three departments participating in the program.

Dissertation:  
A doctoral candidate must enroll in at least 16 credit hours of dissertation work (DATA 7990), maximum of 30 credit hours.
