P Sam Sahil
Research Intern • Research Assistant
Research Intern at Northwestern University, NTU Singapore, and University of Hamburg.
Pivoting from black-box models to principled design. Focused on building systems that are not just performant, but reasoning-capable and transparent.
Research Focus
Interpretability & Trust
Moving beyond "black box" optimization to design transparent AI architectures. Investigating how internal reasoning mechanisms can be made explicit and human-verifiable.
Neuro-Symbolic AI
Bridging the gap between the scale of neural networks and the logic of symbolic reasoning. Developing dual-path architectures (GAT + RoBERTa) to ground semantics in structured knowledge.
Multilingual NLP
Breaking language barriers in emotion detection and polarization. Focusing on cross-lingual generalization to capture nuance across diverse cultural contexts and low-resource languages.
Comp. Social Science
Applying rigorous NLP pipelines to large-scale social data. From geo-tagging historical newspapers to analyzing online polarization to answer fundamental questions.
