Make sense of the mountain of data produced every day

Gather raw data, analyze it, and make decisions. That’s data science in a nutshell.

Data science has become indispensable to industries around the world. How do you know if social media advertising is worth the cost? What is the best way to confirm a life-changing diagnosis from multiple MRI images? Will a tornado touch down in your community? Decipher the data that drives decision-making that changes lives

In this program you’ll merge programming, mathematics, artificial intelligence, machine learning, and analytical skills to answer challenging questions.

Find out how data from sensors, digital images, streaming videos, satellites, medical imagery, and interactions with cloud computing shape our future.

Courses in computer science and statistics will teach you how to leverage technology to analyze large amounts of raw data and extract meaning from clutter. After graduation you’ll put your skills to work in diverse fields including medicine, business, advertising, entertainment, public health, and more.

Co-op = relevant paid work experience

Waterloo's co-op program, the largest in North America, is an amazing way to explore potential careers, learn to interview for jobs, graduate with up to two years of valuable experience — and make money!

Sample co-op job titles

  • Data scientist
  • Risk management intern
  • Developer
  • Software engineering intern
  • Reporting analyst
  • Project manager
  • Enterprise analyst
  • QA analyst

Co-op work-study sequence

Starting in second year, you'll normally alternate between school and work every four months, integrating your classroom learning with real-world experience. You can return to the same employer for a couple of work terms to gain greater knowledge and responsibility or work for different employers to get a broad range of experience.

Your first work term will be after first year (May to August 2026).

Year September to December (Fall) January to April (Winter) May to August (Spring)
First Study Study Co-op
Second Study Co-op Study
Third Co-op Study Co-op
Fourth Study Co-op Study
Fifth Co-op Study -

or halfway through second year (which can be January to April 2027).
