PhD in Complex Systems and Data Science
Build a deep portfolio of research on important, complicated, data-rich problems that matter.

Overview
Our PhD in Complex Systems and Data Science (CSDS) enables students to build a deep portfolio of research on important, complicated, data-rich problems that matter.
Students will receive a wide and rich training in empirical, computational, and theoretical methods for describing and understanding complex systems.
Depending on their chosen area of focus, students will work within and across research groups, and be strongly connected with other students through co-location and regular student-led meetings and events.
The program's scope is science-wide, encompassing natural, artificial, and sociotechnical systems.
Program Goals
Our Essential Goal
To train the deeply skilled and ethical research data scientists the world needs.
Our More Detailed Goal
Our PhD is for students who want to develop a potent portfolio of scientific research into data-rich problems. We want to make this happen.
And as for our Masters, we provide students with a broad training in computational and theoretical techniques for (1) describing and understanding complex natural and sociotechnical systems, enabling them to then, as possible, (2) predict, control, manage, and create such systems.
Foundation
The PhD rests upon our Master's and our five-course Graduate Certificate.
Major Skill Sets
Being a good team member in a highly-collaborative pan-disciplinary, creative research environment that helps solve some of the biggest questions in the world.
Methods of data acquisition, storage, manipulation, and curation.
Visualization techniques, with a potential for building high-quality web-based applications.
Powerful ways of identifying and extracting explanatory, mechanistic stories underlying complex systems—not just how to use black box techniques.
Step 1 Becoming the Crow

Who we're looking for to join our corvine cohort:
Prerequisites
Students must have a Bachelor's degree and preferably a Master's degree in a relevant field and prior coursework in:
- Calculus
- Coding (Python/R ideal but not necessary)
- Data structures
- Linear algebra
- Probability and Statistics
Additional Background: Training in relevant aspects of physics (e.g., statistical mechanics) will be beneficial but not required. Applicants lacking one or more of these prerequisite areas may be accepted provisionally and will be required to complete an approved program of supplementary work within their first year of study.
Evaluation Criteria: Applicants will be evaluated based on their potential for excellence in research, as judged from their academic background, test scores, relevant experience and three (3) letters of recommendation. We will admit students who we believe are most likely to succeed and thrive in the program.
Catch-up Courses Available
Not all three courses can be taken together. At most one of MATH 2522 or CS 2240 may be taken for graduate credit.
Step 2 Your Destination
Create and defend a PhD Dissertation
Consisting of three or more peer-reviewed journal papers. There are many ways to reach this level.
Step 3 Common Core Requirements
Take the first course in each sequence (9 credits) and at least two accompanying second courses:
Option 1: Data Science
Data Science I: CSYS/CS/STAT 5870
Data Science 2: CSYS/CS/STAT 6870
Option 2: Modeling
Modeling Complex Systems: CSYS/CS 6020
Modeling Complex Systems 2
Option 3: Principles
Principles of Complex Systems 1: CSYS/MATH 6701
Principles of Complex Systems 2: CSYS/MATH 6713
Each course scores 3 credits.
Step 4 Notch up 75 or more credits total
Minimum Requirements
- 75 credits total of graduate study approved by your graduate studies committee
- 30 credits minimum of research
- 30 credits minimum of graduate coursework
- 15 credits minimum must be graded (B- or above)
Transfer Credits and GPA
Students may transfer credits from other universities or within UVM following standard UVM policies.
Minimum GPA to graduate: 3.0
Students with two grades below B are eligible for dismissal.

Step 7 Five Stages to Acquire Corvid Cleverness
Stages 1-2: Coursework and Exams
- Completion of 75 credits of coursework with sufficiently high GPA
- Passing of the written comprehensive exams: PhD students sit for a triplet of 1 hour written exams (in 3 subjects) on topics decided upon in consultation with their research advisor(s)
For example, the exams might cover the content found in CSYS 6701, CSYS 6020, and STAT 6870. Students need not have taken all core classes prior to sitting for a particular exam, and the exams need not be taken on the same day. A follow-up oral exam could be scheduled to address material the student failed to demonstrate mastery of during the written exam.
Stages 3-5: Research and Dissertation
- Presentation and defense of the dissertation proposal
- Generation of at least two published or accepted peer-reviewed publications prior to defending their dissertation, with a third at least in peer-review. These publications must be deemed of sufficient breadth, depth, and quality by their Graduate Studies Committee.
- Delivery of a written dissertation and oral defense of the dissertation
