I am an engineering graduate from Department of Electronic and Telecommunications Engineering at University of Moratuwa. My final-year project explored Vision-Language Models for Histopathology Report Generation and was advised by Prof. Ranga Rodrigo.

I am currently working as a Research Engineer at WSO2. Previously, I was a Visiting Research Student at The University of Sydney under the supervision of Prof. Anusha Withana where I worked on human computer interaction research.

I am interested in building mathematically principled generative models for greater efficiency, controlability and generalization across vision and language. More broadly, I am interested in working on flow and diffuson models.

Outside of work, I enjoy playing guitar and game development.
