In the age of AI, data is no longer just a supporting component of research โ€” it has become the foundation of intelligent systems.
Iโ€™m pleased to share the full recording of our session on โ€œ๐—จ๐˜€๐—ฒ ๐—ผ๐—ณ ๐—”๐—œ ๐—ณ๐—ผ๐—ฟ ๐——๐—ฎ๐˜๐—ฎ ๐—–๐—ผ๐—น๐—น๐—ฒ๐—ฐ๐˜๐—ถ๐—ผ๐—ป & ๐——๐—ฎ๐˜๐—ฎ๐˜€๐—ฒ๐˜ ๐—–๐—ฟ๐—ฒ๐—ฎ๐˜๐—ถ๐—ผ๐—ปโ€ conducted as part of the Research in the AI Era series at the University of Peradeniya.
Together with Dr. Isuru Nawinne, we explored how researchers can leverage AI to improve data collection, annotation, validation, and dataset curation while also addressing the growing concerns around bias, ethics, synthetic data generation, and reliability.
One important insight from the discussion was the need for developing datasets that truly represent our own contexts, communities, and real-world challenges. Many AI systems still fail to accurately represent regions like Sri Lanka simply because our data is underrepresented in global datasets.
The session also covered:
โœ… AI-assisted annotation and labeling
โœ… Human-in-the-loop validation approaches
โœ… Ethical risks in AI-generated datasets
โœ… Medical and research data challenges
โœ… Synthetic data generation techniques
โœ… Building scalable data pipelines for AI research
A heartfelt thank you to the organizers, participants, and everyone who contributed to the discussion.

I hope this discussion will encourage more researchers and students to think critically about the role of data in AI innovation.

Exploring how Generative AI is transforming the research lifecycle - from literature reviews and idea generation to data analysis and academic writing.

AI is not a substitute for researchers; it is a powerful collaborator that enhances productivity, creativity, and innovation while emphasizing the importance of critical evaluation, ethical responsibility, and academic integrity.
