Students of Data Science and Decisions

Jessica Boyle

"My favourite part about the Data Science and Decisions degree is that I can customise it to fit my interests.

I get to pick electives from a pool that contains everything from Software Construction to Calculus to Economic Game Theory. This has allowed me to follow my passion for mathematics while also building on my newly discovered love of coding and then I get to throw a bit of economics into the mix!

The combination of courses available in this degree has taught me so many practical skills relevant to being a Data Scientist and I can't wait to test them out on real-world problems when I graduate." 

Serena Xu

“My experience of the Data Science degree has been fabulous so far. I have learnt so many interesting things on a large variety of topics from computer science, maths and economics/business. They have all been incredibly interesting and fascinating, broadening up an entire new way of thinking for me.

One of the highlights of the program is the vast scope of knowledge that we are exposed to, which I believe is incredibly useful in the modern world. We live in a world of technology, which revolves around economics, but is all underpinned by maths and numbers. This program covers all three major areas, which are incredibly useful to contribute to society."

Saksham Yadav

"The data science program at UNSW has provided me with a solid foundation in advanced mathematics and computer science, as well as the opportunity to pursue elective courses in physics. Knowledge of these three fields has proven invaluable to my career as they are fundamental to almost every industry."

Careers in Data Science

Data scientists and analysts use their skills to make discoveries and gain new insights through exploring data. The soaring demand for employees with qualifications in data science and analysis means that career opportunities abound across a range of areas. 

  • The skills of data scientists are so highly coveted due to the sheer volume of data which organisations must contend with. Data scientists have the skills to analyse and interpret the growing volumes and help convert this information into insights, which can transform businesses and industries. Over the last four years, jobs requiring the use of data analysis and data management skills and tools have doubled. Jobs in data science can attract generous remuneration. 

  • "As data volume continues to grow and organisations are looking to become more strategically focused, data science and decision modelling are increasingly essential tools for businesses to thrive in a competitive global environment. Having the right analytical tools is critical for growth and success in the 21st century workplace." 

    Ron Elazar, Senior Consultant at Deloitte Australia. Graduate of UNSW Mathematics and Statistics.

  • “The potential for data analysis to impact big and small decisions in our lives is endless. From forecasting the peaks and troughs of chocolate biscuits in your local supermarket throughout a year, to pushing out intervention programs at the right time to people who are high risk of falling into debt. The best thing? These skills are transferable – the same techniques can be used across multiple applications, the only limit is your imagination.”

    Annelies Tjetjep, Customer Success Manager, SAS Australia.

  • "Every job, every industry, requires more and more analytics, more and more understanding of numbers, and more competency when it comes to looking at problems and modelling things."

    Ben Waterhouse, Founder of Model Solutions, a data analytics and forecast modelling company for the pharmaceutical industry. Graduate of UNSW Mathematics and Statistics.

  • “Data science takes the huge and growing amount of data now available in industry and research, and makes it meaningful and useful. This improves efficiency in business, and allows scientists to answer important questions in fields like climate change and cancer research. ”

    Gordana Popovic, Statistical Consultant at Stats Central UNSW, Former PhD Student (Statistics) at UNSW Mathematics and Statistics.
