Hi, this is Kashob.

I’m 3rd year PhD student in Computer Science at University of Illinois Urbana-Champaign, working with Prof. Kevin C.C Chang. My research is focused on advancing the capabilities of large language models (LLMs) in the fields of Information Retrieval and Retrieval-Augmented Generation. My primary emphasis is on enhancing Knowledge and Reasoning within LLMs, which includes: i) Knowledge: Enhancing factuality and improving retrieval-augmentation methods; ii) Reasoning in multi-agent systems: Developing LLM-based multi-agent systems for complex reasoning task.
