Hi there! I’m Abhinav, a senior at UIUC majoring in Computer Science. My research focuses on preference learning and reasoning in large language models. I am fortunate to be advised by Prof. Dilek Hakkani-Tür and Prof. Heng Ji.

Currently, I am exploring scientific reasoning in LLMs at ConvAI Lab and working as a research intern at Sandia National Labs.

Feel free to reach out to me at achinta3[at]illinois[dot]edu.
