Mathematical Approaches to Smart Energy & Information Systems Design
Mathematical Approaches to Smart Energy & Information Systems Design
Embedded Files
Our laboratory conducts research at the intersection of systems control, energy, and information and communication technologies. Building on a broad range of academic disciplines—including
Systems and Control Theory, Informatics, Big Data Science, Mathematical Optimization, and Software Engineering
—we study the mathematical foundations that enable future social infrastructure systems. Our work focuses particularly on:
Smart Grids = Next-generation power systems that maximize the utilization of renewable energy
Beyond 5G/6G = Next-generation information and communication networks beyond fifth-generation mobile systems
The “mathematical science” we pursue is not merely the manipulation of equations. Instead, it is a discipline that uncovers the essential principles and structural mechanisms behind complex phenomena using mathematics. By extracting and understanding the hidden structure of modern large-scale social systems, we aim to design optimal and sustainable infrastructure for the future.
