👋 Hi, my name is
Suchinthaka Wanninayaka
I'm a Ph.D. Candidate & ML Researcher
Passionate Machine Learning researcher with 5+ years of experience in Generative AI, Computer Vision, and Deep Learning. Specialized in image reconstruction, multimodal learning, and Semantic Communication frameworks.

About Me
I am a Ph.D. Candidate in Electrical and Computer Engineering at UC Davis, researching cutting-edge Machine Learning and AI systems. My work focuses on Generative AI, Diffusion Models, and Semantic Communications.
I have a strong track record of designing scalable and efficient AI-driven solutions for visual understanding, image generation, and communication-oriented tasks. My research pushes the boundaries of modern AI through innovative frameworks like Diff-GO, LaMI-GO, and TACO.
When I'm not doing research, I enjoy building full-stack applications and exploring new technologies. Previously, I worked as a Software Engineer at Axiata Digital Labs and Codify Lanka, developing enterprise-grade platforms.
