Research Interests and Experience

As the lead enterprise fellow in bioprocessing, my focus is to convert research ideas into useful products which will enable biomanufacturing and the biotech industry as a whole. I currently lead the technology commercialisation of the ultra scale-down (USD) technology platform developed in the department to help speed up bioprocess development.

My research interests lie in the area of bioseparation and purification (eg  filtration, centrifugation, chromatography). In particular, I am interested in the development and application of:
•    innovative solutions to accelerate bioprocess development and gain understanding of biomanufacturing operations (eg ultra scale-down methodologies and other process analysis tools); and
•    process engineering and economic models for technology assessments and improvements.  

My recent industry experience as a senior consultant engineer involved evaluating technology and process options; creating process, cost or manufacturing capacity models to support business cases of bioprocess options; and bioprocess software product management and development.

Previously, I was a lecturer in chemical engineering in the Philippines and was a key investigator on plant-based bioproducts (eg biofuels, bioactive compounds).
