Dr. Tek Raj Chhetri


Dr. Tek Raj Chhetri is a Postdoctoral Associate at the Senseable Intelligence Group at the McGovern Institute for Brain Research at the Massachusetts Institute of Technology and the founder and director of CAIR-Nepal, an artificial intelligence research organization in Nepal.

He conducts research in artificial intelligence, Large language models (LLMs), LLM-based multi-agent systems, semantic web, data privacy, and Internet of Things (IoT) data sharing. Details about his current research are available at docs.brainkb.org. 

Wondering what knowledge graphs are? Imagine this: when you know someone’s friends, you naturally start to understand more about that person—their interests, values, and background—because their friends give you context. Knowledge graphs work in a similar way. They connect bits of information and reveal how they relate to each other, allowing us to understand complex topics through their relationships. It’s like building a smart, interconnected map of knowledge that helps us see the bigger picture.
