The field of semiconductor-based electrochemical systems focuses on integrating semiconductor technology with electrochemical platforms to enable precise control and monitoring of electrochemical processes at the micro- and nanoscale. By leveraging semiconductor systems, researchers can induce and observe subtle electrochemical reactions and monitor minute changes in real-time, leading to the discovery of new mechanisms and previously undetectable chemical and physical transformations. Developing such advanced systems requires comprehensive research spanning semiconductor fabrication processes and specialized semiconductor packaging tailored for electrochemical applications. This interdisciplinary approach holds the potential to revolutionize electrochemical sensing, catalysis, and energy conversion technologies by offering unprecedented sensitivity and control.

Our laboratory is conducting research to develop semiconductor-based electrochemical systems capable of individually controlling hundreds to tens of thousands of electrodes. We are also working on designing customized electrochemical systems tailored to various applications, including biosensing, bio-synthesis, and electrochemical catalyst analysis.

Biological computing systems, including neural network and DNA computing, are essential for advancing next-generation information processing technologies. Neural network-based computing mimics the brain's parallel processing capabilities, offering powerful solutions for complex pattern recognition, decision-making, and learning tasks. DNA computing, on the other hand, leverages the inherent information storage and processing capabilities of DNA molecules, enabling ultra-dense data storage and massively parallel computation with minimal energy consumption. Together, these systems have the potential to overcome the limitations of traditional silicon-based computing, paving the way for revolutionary applications in artificial intelligence, personalized medicine, and data-driven scientific discovery.

Our laboratory is conducting research to elucidate the principles of biological computing systems by monitoring and emulating neural networks. Additionally, we are developing technologies to store data in DNA by synthesizing desired DNA sequences simultaneously and in parallel on semiconductor chips.

Research on electrocatalytic systems, including CO₂ reduction, hydrogen evolution, and oxygen evolution reactions, is crucial for developing sustainable energy solutions and addressing global environmental challenges. CO₂ reduction offers a pathway to convert greenhouse gases into valuable fuels and chemicals, contributing to carbon neutrality. Hydrogen evolution is central to clean hydrogen production, a key component in the transition to renewable energy sources and the development of hydrogen-based energy economies. Oxygen evolution, essential in water splitting and metal-air batteries, plays a critical role in efficient energy storage and conversion systems. Advancements in these electrocatalytic processes are vital for creating scalable, efficient, and eco-friendly energy technologies, ultimately supporting the shift towards a sustainable, low-carbon future.
