Specialization / Research Interests
My research explores how seaweeds (brown and green macroalgae) can be converted into renewable energy in salt-rich environments using anaerobic digestion. I work from small laboratory tests to practical bench-scale projects, prioritizing simple, reliable designs, process stability, and clean methane production. I’m interested in pretreatment, co-digestion with coastal by-products, and ocean-related applications that support the blue and circular bioeconomy. I approach my research goal with a space technology mindset: solutions should be closed-loop, resource-efficient, and robust under constraints.
Message to Students
I like to keep science simple: the universe has two core ingredients: energy and space. When we study how energy moves and how space constrains it, we can understand the natural world and evaluate technologies responsibly. In GLA, we study oceans and other environments through this lens, using observation, measurement, and clear reasoning to make sense of complex systems. Sustainability grounds our approach, and the same thinking appears in space technology: close cycles, respect limits, and keep systems reliable under constraints through closed loop, resource efficient, robust practices. You do not need a heavy science background; curiosity, careful thinking, and a willingness to learn are enough. If this way of thinking resonates with you, see me at GLA. I would be glad to help you grow a scientific mindset for evidence-based understanding.
