Welcome to Thinh’s homepage!

Hi, I am a second-year PhD student at Virginia Tech (VT), advised by Prof. Tu Vu. My research focuses on effective and efficient methods to advance reasoning skills for search-augmented large language models and intelligent web search agents.

Previously, I spent 2 years working as an AI Resident at VinAI Research under the supervision of Dr. Dat Quoc Nguyen. Prior to that, I completed my bachelor’s degree in Computer Science at University of Science, Vietnam National University, Ho Chi Minh city.

🌟 Research interests

I am now focusing on improving LLMs’ reasoning skills by injecting knowledge from external tools, including:

• Search-augmented LLMs: enhancing LLMs with search capabilities for more accurate and up-to-date knowledge.
• Web search agents: designing effective approaches to enable agents to find accurate information in noisy web environments.
• Advanced reasoning: developing methods to improve LLMs’ ability to engage in sophisticated reasoning processes.
