Steerable Adversarial Scenario Generation through Test-Time Preference Alignment
Poster presentation at ICLR 2026 for SAGE, where I presented our preference-aligned adversarial scenario generation work for safer autonomous driving.
IEEE ITSC 2025 Invited Session Co-Chair
Session co-chair for the invited session on innovative applications of large language models in multimodal transportation systems.
Collaborative Time Series Imputation through Cross-city Meta Learning
Poster presentation at ICLR 2025. I presented our cross-city meta-learning work and had many valuable conversations on implicit neural representations and urban time-series learning.
Exploring the Roles of LLMs in Transportation Systems
Invited talk at the TRZ Youth Forum, discussing our LLM4TR framework, case studies, and open questions around LLM-powered transportation systems.
