Overview
What the Master of Science in Catastrophe Modeling and Resilience is
Catastrophe modeling extends traditional actuarial science to rare events. Modelers and resilience specialists study how interdependent infrastructure systems and communities hold up under outside shocks, and what it takes to prepare for and recover from them.
The program is built on engineering and blends in data science, actuarial science and the social sciences. You get a broad grounding in the many facets of catastrophe, risk and resilience modeling, then go deeper in one area of application, such as infrastructure resilience against disasters, forecasting of epidemics, or probabilistic modeling applied to engineering and science.
Applicants come from engineering, mathematics, computer science, economics, earth and environmental sciences, epidemiology and meteorology. If you know basic probability and statistics, calculus, linear algebra and programming, you are ready to start. Others may begin with leveling courses, and some core courses are open to every student while they do.
A 30-credit degree, typically 1.5–2 years of full-time study, delivered on campus, hybrid or fully online.

Curriculum
What you study
The degree requires 30 graduate credits: 15 credits of required core courses, a 3-credit project-based course, 9 credits of approved electives and one 3-credit free elective.
- Required core, 15 credits. Catastrophe Modeling and Resilience (CAT 401), Applications of Catastrophe Modeling and Resilience (CAT 402), Mathematics of Actuarial Science (CAT 403), Introduction to Data Science (DSCI 310), and either Mathematical Methods in Engineering I (ENGR 452) or Numerical Methods for Scientists and Engineers (BIOE 463).
- Project-based course, 3 credits. Choose the capstone (CAT 411), supervised research (CAT 412) or a thesis (CAT 490).
- Approved electives, 9 credits. Select three courses from a list that spans statistics and programming, structural reliability and random vibrations, GIS and deep learning, climate and earth system modeling, environmental policy and justice, and advanced probability, stochastic processes and financial stochastic analysis. Some electives have prerequisites, so not every student has access to every option. No more than a combined total of 6 credits in CAT 412 and CAT 490 can count toward the degree.
- Free elective, 3 credits. One course at the 300 or 400 level, chosen from the approved electives or from another department.
- Course-level rules. At least 24 credits must be at the 300 and 400 level, with 18 of them at the 400 level, and research or thesis registration can count toward the 400-level requirement. At least 18 credits must be in the major field, with 15 of them at the 400 level. You need a B- or better in at least 18 credits of your program and in all 300-level courses in the major field, and courses graded C- or better count toward the degree.

Careers
Where this work leads
Catastrophe modeling and resilience specialists work wherever organizations need to understand and plan for rare, high-impact events.
Professionals in this field build and run models that estimate how likely a disaster is and what it would cost, then turn the results into decisions about insurance, investment, infrastructure and emergency planning. Typical settings include insurance and reinsurance companies, catastrophe modeling firms, specialized financial management firms, and consulting firms that assess resilience, along with emergency management agencies, local administrations and federal agencies. Early roles often center on building and validating models and analyzing data. With experience, people move toward leading modeling teams, advising clients on risk strategy, or directing resilience programs.
