The Ph.D. Programme in Electrical and Computer Engineering (PDEEC) addresses the scientific areas of Computers, Electronics, Energy, Systems, Decision and Control, and Telecommunications.  A brief description of these areas is given below.

Computers

The Scientific Area of Computers at DEEC comprises a faculty body of 24 PhD professors, distributed across five multidisciplinary research units.
The area focuses on the scientific principles and on the technologies for designing and implementing hardware and software for computational systems and communication networks. It offers curricular units that cover different domains of Computer Engineering in the undergraduate, master's, and doctoral programmes at Técnico, maintaining a strong connection with advanced research activities.
The research lines developed include topics as diverse as computer networks, computer architecture, systems programming, multimedia processing and communication, intelligent computing, and artificial intelligence.

Electronics

The Scientific Area of Electronics has a strongly multi-disciplinary profile, teaching basic courses in electronic devices and circuits, but also advanced courses in the areas of microelectronics, computer electronics, power electronics, radio frequency, digital signal processing and optoelectronics.

Energy

The Energy Scientific Area of DEEC provides the Técnico community with a set of human and laboratory resources specially designed to equip students in areas related to Electrical and Computer Engineering with the critical skills to address the main challenges of the energy transition. These challenges range from the planning and operation of power systems with high renewable energy penetration to the design of electronic and electromechanical devices for energy production, storage and utilization.

Systems, Decision and Control

Decision and Control Systems (SDC) is a scientific area within the DEEC with a faculty of 30 professors holding PhDs. The SDC area provides 24 courses across 5 Master programs and 18 courses across 5 Doctoral programs at Técnico, and is heavily involved in research activities. The research conducted covers topics as diverse as signal and multimedia analysis, systems control, computer vision, natural language processing, robotics, and artificial intelligence.

Telecommunications

The Telecommunications Scientific Area carries out research in communication and networking technologies, from the physical layer to end-to-end services. Its faculty brings internationally recognized expertise in 5G/6G mobile networks, IoT and radio planning, signal processing and machine learning/AI, multimedia and image/video compression, optical communications and photonics, antenna technologies and nanophotonics, as well as quantum communications and security. In a demanding and collaborative academic environment, PhD students engage in competitive projects and industry partnerships, contributing to new solutions with impact on next-generation connectivity.
