Anaerobic fermentation
Statistical analsyes and machine learning
Our research focuses on producing bioenergy and biofuels from organic wastes through fermentation and anaerobic digestion processes. To achieve this, we investigate strategies to maximize microbial activity and enhance both waste treatment efficiency and energy productivity by improving process design and applying hybrid systems. In particular, we systematically analyze the abundances and functions of microbial communities and functional genes to elucidate their relationships with process performance, while also exploring the physiology and activation strategies of specific microorganisms in depth. We further integrate statistical analyses and machine learning approaches to identify key drivers of process performance, predict microbial and operational responses, and develop data-driven strategies for system optimization. Based on this understanding, we aim to develop high-efficiency bioenergy and biofuel production technologies.
2.Bioremediation for persistent contaminants
Our research focuses on developing microbial bioremediation technologies for persistent contaminants, including per- and polyfluoroalkyl substances (PFAS). We aim to identify microorganisms with high potential for removing specific contaminants from complex microbial communities and to enhance their activity and growth in order to develop sustainable and cost-effective treatment processes that can serve as alternatives to conventional remediation technologies. Particular emphasis is placed on systematically analyzing the composition and functions of microbial communities to elucidate their relationships with contaminant removal performance, as well as on exploring the physiological traits and activation strategies of key microorganisms. To achieve this, we employ a wide range of molecular biological tools to uncover the microbial mechanisms involved in contaminant degradation and removal, ultimately enabling the development of efficient and sustainable bioremediation processes.
3.Biochar application for net-zero
Our research focuses on producing biochar from organic wastes through pyrolysis and developing value-added applications across diverse industrial sectors to support sustainability and net-zero goals. We aim to convert a wide range of organic waste streams into functional biochar materials and utilize them in agriculture, white biotechnology such as anaerobic digestion and fermentation, as well as in industrial applications including electrode and concrete materials. Particular emphasis is placed on understanding the physicochemical properties of biochar and tailoring its functionality for specific applications, thereby enhancing resource recovery, process performance, and material value. Based on these approaches, we seek to develop sustainable biochar platforms that contribute to waste valorization, carbon sequestration, and the transition toward a circular and net-zero economy.
