There are many exciting areas of research currently being explored by PhD students in electrical engineering. Some prominent topics include power systems, renewable energy, communications and signal processing, electronics and semiconductors, control systems, and electromagnetics.
Power systems is a growing field as the world moves towards more sustainable energy sources. PhD researchers are studying ways to modernize and strengthen existing power grids to integrate diverse renewable energy sources like solar and wind farms. Topics include distributed energy resources, microgrids, smart grid technologies, demand response, transmission line monitoring, and system stability under normal and abnormal conditions. For renewable energy specifically, some areas of focus are solar photovoltaic cell materials and designs, wind turbine technologies, energy storage systems, and hybrid renewable plants.
In communications and signal processing, cutting edge work is being done in wireless communications, optical fiber communications, information theory, machine learning for communications, and radar and sensor systems. Wireless research includes 5G and beyond networks, MIMO techniques, millimeter wave communications, full duplex radios, and signal processing for IoT devices. For optical communications, topics span high-speed fiber transmission, nonlinear signal processing, network coding, free-space optics, and quantum communications. Machine learning is also being widely applied to improve communications systems like cognitive radios.
Semiconductor device fabrication and materials science remain active areas for electrical engineering PhDs. Researchers are developing new materials and device structures for applications such as flexible electronics, integrated photonics, quantum computing, power devices, and bioelectronics. Specific subjects of investigation involve carbon nanotubes, 2D materials like graphene, III-V and strained silicon technologies, spintronics, neuromorphic computing, and nanoelectromechanical systems. Process techology and modeling are equally important, with work on topics like 3D chip stacking, heterogeneous integration, and thermal management techniques.
Control systems engineering is enabling increasing levels of automation across many industries. PhD projects range from fundamental control theory to application areas like robotics, autonomous vehicles, precision motion control, haptics, and bionics. The use of learning and data-driven approaches like reinforcement learning, deep learning, and model predictive control applied to systems with complex, uncertain dynamics is a major area of growth. Electrical engineers also conduct research in fields touching electromagnetics like antennas, metamaterials, nanophotonics, plasma physics, and biomedical imaging and sensing modalities.
This covers just a high-level overview of some of the exciting research directions for PhD students in today's electrical engineering landscape. As technology needs accelerate and converge across multiple domains, opportunities will continue growing in interdisciplinary fields that integrate EE principles with other areas like materials science, computer science, mechanical engineering, health technologies, and more. Overall, the field remains rich with possibilities for innovators who want to push the boundaries of what's possible and solve pressing challenges through advanced technologies.
