About Me

Hi, I'm Alimohammad (Ali) Beigi! I'm a Ph.D. candidate in Computer Science at Arizona State University, where I am fortunate to be mentored by Dr. Huan Liu and work in the DMML Lab. I also serve as a teaching assistant and instructor at ASU.

I hold a bachelor's degree in Mathematics and Applications from the University of Tehran and a master's degree in Computer Science from Shahid Beheshti University.

My research sits at the intersection of causality, machine learning, NLP, and trustworthy AI. I work on projects including:

  • Causal Feature Selection: Redefining CFS to go beyond Markov Blanket discovery and support predictive modeling, fairness, treatment-effect estimation, and domain generalization.
  • LLMs for Fact-Checking: Building multimodal fact-checking systems that generate and answer relevant fact-checking questions using LLMs and VLMs.
  • Digital Twins for Decision-Making: Combining causal discovery, reinforcement learning, and LLM-augmented reasoning for battlefield and disaster-response scenarios.
  • Disaster Assessment: Leveraging BERT-based embeddings, multimodal news/Reddit data, and county-level property damage labels (SHELDUS) to model and predict disaster impacts.

Beyond academia, I explore applied AI and entrepreneurship. Currently, I am working on a Remote Therapeutic Monitoring (RTM) mobile app for chronic pain management, integrating CBT-style prompts, daily symptom tracking, and LLM-powered chat flows.

Outside research, I am a BMW enthusiast, enjoy travel, creative writing, and building communities through collaboration and mentorship.

If you have any questions about my work, research, academia, or programming, feel free to reach out!

Projects

LRQ-FACT: Multimodal Fact-Checking with LLM/VLM-Generated Questions
Framework where LLMs/VLMs generate relevant fact-checking questions and answer them via RAG over trusted sources, improving F1 by up to 10% on MMFakeBench; includes ablations, random-question baselines, and runtime analysis (BigData’25).

Interventional Disaster Assessment via Causal Attribution
Real-time disaster assessment using causal graphs for scenario simulation, attribution scoring, and practical counterfactual strategies; leverages multimodal signals (news, Reddit) aligned with SHELDUS county-level labels (CIKM’25).

LLM-Heuristic Local Causal Discovery
Augments local structure learning with LLM heuristics to disambiguate edges when CI tests are brittle.

Model Attribution in LLM-Generated Disinformation
Domain-generalization + supervised contrastive learning pipeline to separate human vs. LLM-generated text and infer the likely source model—achieving a 7% accuracy gain (DSAA’24).

Digital Twin for Decision-Making
A pipeline that fuses causal discovery (PC, GES, NOTEARS), RL objectives, and LLM-augmented graph extraction to support scenario exploration and policy testing for battlefield/disaster-response settings.

CBT-based Remote Therapeutic Monitoring (RTM) App for Chronic Pain
Co-building an RTM mobile app with clinicians and engineers: daily symptom tracking, CBT-style prompts, and LLM-powered chat flows. Focus on patient–provider loops, CMS RTM billing flows, concurrency-safe chat, and user-specific memory.
