About the course

Harvard Business Review recently described the job of Data Scientist as “the sexiest job of the 21st century”. Data science is about doing some detective work and carrying out the investigations needed to inform important decisions and to predict new trends. Technology is growing and evolving at an incredible speed, and both the rate of growth of data we generate and the devices we use to process it can only increase.

At Essex, we help you to understand how utilising the speed and processing-power of computers can assist in using data to make better decisions. You discover the new methods and the smart, unusual questions needed to make sense of both numerical and textual data. Your course balances solid theory with practical application through exploring topics including:

  • Computer science and programming
  • Databases and mathematical skills
  • Ethical issues around the use and processing of data
  • Specialist skills in the areas of big data, data analytics and data science

You don’t need to know any computer programming before you begin the course, and as you study a module on the mathematics required for data science, you don’t need an A-level in mathematics either.

A successful career in data science requires you to possess truly interdisciplinary knowledge, so we ensure that you graduate with a wide-ranging yet specialised set of skills in this area. You are taught mainly within our School of Computer Science and Electronic Engineering, but also benefit from input from our Department of Mathematical Sciences, Essex Business School, and our International Academy.

Data scientists are required in every sector, carrying out statistical analysis or mining data on social media, so our course can open the door to almost any industry, from health, to government, to publishing.

Study abroad

Your education extends beyond the university campus. We support you extending your education through providing the option of an additional year at no extra cost. The four-year version of our degree allows you to spend the third year studying abroad or employed on a placement, while otherwise remaining identical to the three-year course.

Studying abroad allows you to experience other cultures and languages, to broaden your degree socially and academically, and to demonstrate to employers that you are mature, adaptable, and organised. Popular destinations include:

  • The United States
  • Europe
  • Canada
  • Australia
  • New Zealand
  • Latin America
  • The Middle East
  • Hong Kong
  • Japan

Placement year

Alternatively, you can spend your third year on a placement with an external organisation, as part of one of our placement year degrees. The learning outcomes associated with this programme focus on using the specialist technical skills acquired in the first two years of the course and developing communications skills with customers. You will be responsible for finding your placement, but with support and guidance provided by both your department and our Employability and Careers Centre.

Students are provided with support to secure a placement. Recent placements undertaken by our students have been with ARM, Microsoft, Intel, Nestlé, British Aerospace, and the Rutherford Appleton Laboratory, as well a range of SME software and hardware companies.

Your future

Demand for skilled graduates in the areas of big data and data science is growing rapidly in both the public and private sector, and there is a predicted shortage of data scientists with the skills to understand and make commercial decisions based on the analysis of big data.

The University of Essex is bridging the gap between academia and business, and we are at the forefront of helping the UK grasp the big data opportunities to get ahead in the global race. Our graduates in data science have been very successful in finding employment in the public sector, consulting, technology, retail, and utilities, while a number have gone on to postgraduate study or research.

Our recent graduates have gone on to work for a wide range of high-profile companies including:

  • BT
  • EDS
  • IBM
  • Royal Bank of Scotland
  • Accenture
  • Google
  • Force India F1

Our School has a large pool of external contacts, ranging from companies providing robots for the media industry, through vehicle diagnostics, to the transforming of unstructured data to cloud-based multidimensional data cubes, who work with us and our students to provide advice, placements and eventually graduate opportunities.

We also work with the university’s Employability and Careers Centre to help you find out about further work experience, internships, placements, and voluntary opportunities.

Example structure

Studying at Essex is about discovering yourself, so your course combines compulsory and optional modules to make sure you gain key knowledge in the discipline, while having as much freedom as possible to explore your own interests. Our research-led teaching is continually evolving to address the latest challenges and breakthroughs in the field, therefore to ensure your course is as relevant and up-to-date as possible your core module structure may be subject to change.

For many of our courses you’ll have a wide range of optional modules to choose from – those listed in this example structure are just a selection of those available. The opportunity to take optional modules will depend on the number of core modules within any year of the course. In many instances, the flexibility to take optional modules increases as you progress through the course.

Our Programme Specification gives more detail about the structure available to our current first-year students, including details of all optional modules.

Please note that depending on your entry grades you will take either Mathematics for Data Science or Linear Mathematics in your first year, but not both.

Year 1

This module introduces students to three key aspects of professional development. These are product development, team work, and project management. In teams of six you work throughout the year to develop a performance for a Nao robot, with a Python module at the core of the product. Apart from the core skills you also learn about contextual issues such as intellectual Property (IP), sustainability, ethical issues, and health & safety. The module is a great opportunity to build a product in a team of fellow students and have that wonderful feeling of having created something original.

Understand the theory and practice of distributed computing technology. Examine conventional techniques (eg Sun Java RMI) and web-based middleware techniques, like web services.

The world demands software systems with ever increasing richness of behaviours and degrees of complexity. However, traditional software engineering techniques, which were inherited with relatively minor adaptations from other, older branches of engineering, have been struggling to scale up to the challenges posed by modern software systems. As a result, a large proportion (as much as a quarter!) of software projects based on traditional methods end up being cancelled at some point in their lifecycle, with many more being late, over budget and with less features than initially stipulated. In this module you will learn why traditional software engineering techniques fail, and you will become very familiar (through lectures, labs, videos and a large group project) with a novel set of techniques, known as Extreme Programming and Agile Software Development, which fundamentally solve these problems. In the last decade, these techniques have been so successful that today as many as 80% of all projects adopt agilite methods.

As humans we are adept in understanding the meaning of texts and conversations. We can also perform tasks such as summarize a set of documents to focus on key information, answer questions based on a text, and when bilingual, translate a text from one language into fluent text in another language. Natural Language Engineering (NLE) aims to create computer programs that perform language tasks with similar proficiency. This course provides a strong foundation to understand the fundamental problems in NLE and also equips students with the practical skills to build small-scale NLE systems. Students are introduced to three core ideas of NLE: a) gaining an understanding the core elements of language--- the structure and grammar of words, sentences and full documents, and how NLE problems are related to defining and learning such structures, b) identify the computational complexity that naturally exists in language tasks and the unique problems that humans easily solve but are incredibly hard for computers to do, and c) gain expertise in developing intelligent computing techniques which can overcome these challenges.
