Digital and Green Science and Engineering

This field aims to establish new engineering paradigms for a sustainable society by integrating information technology with electrical and electronic engineering.
Core research areas encompass nonlinear systems, energy systems and mobility, statistical machine learning, biomedical signal processing, cyber-physical dynamical systems, and intelligent circuit design. These are complemented by specialized research in optical quantum information science, optoelectronic materials, and the mathematical foundations of networks in machine learning. Together, these disciplines bridge the gap between physical phenomena in the real world and the complex structures of data and information.
By fostering synergies between the physical models of energy and devices and advanced information technologies—such as data analytics, machine learning, and optimization—this field seeks to define new design principles and analytical methods that transcend traditional disciplinary boundaries. Ultimately, the goal is to cultivate professionals who possess a deep understanding of both information and physical systems, enabling them to pioneer next-generation technologies that support a green society.

Electrical, Systems, and Biomedical Engineering

This field focuses on the comprehension and control of complex systems—ranging from engineered systems to living organisms and biological processes—grounded in the fundamental theories and technologies of electrical engineering.
Key research areas encompass digital control theory and its applications, non-contact human sensing, superconducting technologies, computational electromagnetics, space radio engineering, and microwave engineering, as well as advanced electrical devices designed to minimize environmental impact.
By integrating physical insights with mathematical modeling, measurement, control, and system design, this discipline contributes to diverse sectors including energy, healthcare, communications, space, and environmental technology. It aims to develop engineers who can analyze complex phenomena through both theoretical and experimental lenses, ultimately synthesizing these insights into robust, controllable systems.

Photonics, Electronics, and Quantum Science and Engineering

This field is dedicated to advancing next-generation devices, measurement techniques, and information technologies by exploring the fundamental interactions between light, electrons, spins, and matter.
Major research topics encompass wide-bandgap semiconductor materials and their applications in power electronics; optical quantum information processing, communication, and metrology; the quantum control of light and matter for ultra-precise measurement; and the exploration of solid-state quantum materials through spintronics and spin-based sensing. Further areas of focus include superconductivity, magnetism, molecular electronics, and photonic crystals.
Covering a full spectrum of research activities—from fundamental physical insights and material synthesis to device development and applications in measurement and information science—this field aims to nurture leaders capable of spearheading cutting-edge research on both academic and international stages.
