Biography

I have been working on bio-analytical techniques and developing fluorescent tags which can be useful for biological imaging during my PhD (University of Oklahoma USA). I continued to work on molecular and cell biology after my PhD, focusing on aptamer-ligand interactions and developing applications to medical technology. Also I studied interactions amongst proteins (Mms6) that promote crystallization of iron in magnetotactic bacteria, expanding my area of work beyond pure cell biology. After returning to Sri Lanka, I’ve been working on optimizing a cost-effective screening tool to analyze urine protein in the lower range, using a 25% SSA method. My long-term objective is to share my knowledge in bio-analytical chemistry together with my teaching experience to empower the future Sri Lankan healthcare workforce, using available resources in Sri Lanka. I enjoy listening to music, singing, bird-watching, hiking and working with children.
