Zoher Kachwala

I am currently pursuing a PhD in Computer Science at Indiana Universityâs Luddy School of Informatics, Computing and Engineering, under the guidance of Professor Filippo Menczer. I am actively involved in the Observatory on Social Media and the NaN research group. I also have the privilege to collaborate with Professor Jisun An and Professor Haewoon Kwak.
My research focuses on enhancing LLM reasoning during inference, particularly at the token decoding stage. I aim to identify patterns that estimate a modelâs confidence in its responses and develop methods to improve this confidence through guided decoding.
I approach this in two key ways. First, I explore diverse chains of thought and implement advanced voting/aggregation mechanisms that consider not only top-ranked answer tokens but also lower-ranked alternatives. Second, I enhance the modelâs reasoning by incorporating soft signals, such as answer labels, to guide its chain of thought toward more accurate responses.
