My current work is to understand how the texture, microstructure and flavour develop in Swedish long-ripened hard cheese, in relation to raw milk composition and properties. The project is implemented in collaboration between SLU (Uppsala and Umeå) and Norrmejerier, Umeå.

Presentation

I am a PhD student in Food Science at Åse Lundh Lab, Department of Molecular Sciences. My major focus area is dairy (cheese) technology. I have involved in many extracurricular activities during my PhD (i.e. Organizing a study trip, a symposium and chairing the SLU's PhD council). A well-organized, strategic, result-oriented and enthusiastic team player. Confident and influential communicator with good scientific practices (i.e. Departmental social media coordinator, invited to deliver speeches & various presentations, popular articles and scientific papers; see below). 

I obtained Erasmus Mundus Food of Life double masters from University of Copenhagen (MSc. in Food Science) and Swedish University of Agricultural Sciences (MSc. in Animal Science). I obtained my bachelor’s degree (first class division) in Agricultural Technology and Management from the University of Peradeniya, Sri Lanka.

Teaching

Teaching in Food Chemistry and Physics (LV0105) MSc. Course - Enzymes in Food

Lab assistant/demonstrator in Animal Food Science (LV0099) MSc. Course
1.) Milk coagulation and rheology lab exercise 
2.) Meat texture and colour lab exercise 

Research

I am applying several food structure chracterization methods such as; hyperspectral imaging, microscopic (confocal, electron and flurocence) imaging, rheological techniques and other advanced food strucutre measuring techniques to track the changes over the ripening period. Development of aroma components and sensorial properties will be analyzed both qualitatively and quantitatively (sensory pannel and headspace GC-MS).
