Professional & Research Experience

Mar 2026 — Present Amirkabir University of Technology Under Dr. Momtazi

Undergraduate Researcher: LLM Evaluation & Benchmarking

  • Curated and annotated high-quality, multi-domain benchmark datasets across diverse categories, including Medical and Religious domains, ensuring robust data preparation for model ingestion.
  • Conducted comprehensive evaluations of state-of-the-art generative language models (e.g., LLaMA, Qwen, Mistral) to systematically track response accuracy and answer correctness.
  • Analyzed model performance limitations and behavioral edge cases, focusing on measuring hallucination rates and evaluating domain-specific knowledge alignment.

Undergraduate Researcher: Autonomous Driving & Simulation

  • Tested and benchmarked diverse open-source autonomous vehicle control and end-to-end planning models within the CARLA simulation framework.
  • Integrated system nodes with Autoware and ROS2 stacks to evaluate vehicle behaviors, lane-keeping, and routing under various environmental conditions.
Mar 2026 — Present Amirkabir University of Technology Under Dr. Javanmardi

Undergraduate Researcher: Autonomous Driving & LLM Agents

  • Developed agentic decision-making frameworks based on Generative LLMs for autonomous vehicles as an alternative to traditional rule-based behavioral planners.
  • Designed integration pipelines connecting high-level LLM agent outputs with ROS2 / Autoware lower-level planning and control modules.
  • Reviewed contemporary literature on foundation models for robotics to draft simulated scenarios and evaluation suites for testing planning logic.
Mar 2025 — Feb 2026 Amirkabir University of Technology Under Dr. Nazerfard

Undergraduate Researcher: NLP & Large Language Models

  • Conflict Prediction: Utilized transformer-based architectures (BERT, GPT-style models) to parse and process political speeches and social-media texts for predicting underlying tension patterns.
  • Cross-platform Profile Mapping: Implemented feature extraction and representation learning workflows to map user profiles across platforms using textual alignment.
  • Big Data Analysis: Explored distributed processing architectures and engineered medium-scale preprocessing pipelines to handle textual data challenges.
