Professor Han’s research seeks microbially-mediated solutions and electrochemical approaches for critical environmental issues such as bioenergy production and environmental pollutions.
His studies primarily focus on the production of biofuels from biomass, specifically from microalgae, and of related processes: cultivation, cell harvesting, and lipid extraction.
His research also includes applications of various electrochemical techniques, providing different methods and solutions to air pollution problems. All the while, microbial processes and hydrodynamic cavitation have been steadily studied for effective application to wastewater treatment systems.
He has applied the use of a number of physiological, chemical, and molecular genetic techniques to his studies, underscoring the utility of both classical and newly developed methods in the pursuit of fundamental questions in Environmental Biotechnology.
