Researcher biography
My research portfolio integrates, at a deep level, fundamentals of process engineering and molecular & microbiology across applications including biominerals engineering, bioenvironmental systems, valorisating & repurposing waste, bioproducts and algal biotechnology. Integrating microbial dynamics and structure – function relationships informs building robust & resilience bioprocesses and novel bioproducts. Using IDTD research, I seek sustainable approaches to mineral & water-sensitive systems
