Experience
Research Assistant
Aug 2024 — Present · Houston, TX, US
Role Overview:Driving data-driven research and simulations in the Connected and Autonomous Vehicles (CAV) domain, with a focus on large-scale traffic modeling, geospatial data integration, and V2V communication system development to enable safer and smarter transportation systems.Key Responsibilities:*Designed and built data pipelines to process real-world geospatial data (OpenStreetMap, live traffic feeds) into structured inputs for simulation frameworks such as CARLA, SUMO, and OSMnx.*Modeled dynamic road networks and traffic flows, integrating sensor data and environment-based variables.*Developed V2V communication systems and visual analytics tools to track congestion, efficiency, and rerouting behavior.*Implemented Intelligent Driver Models (IDM) and dynamic rerouting strategies for realistic simulation of autonomous driving.*Conducted cybersecurity risk analysis on simulated CAV networks and proposed software-based mitigation strategies.Key Achievements:*Delivered scalable traffic simulation systems capable of ingesting multi-source data for congestion prediction and routing optimization.*Created density-based heatmaps and geospatial visualizations using Python and GIS libraries to analyze real-world traffic behaviors.*Built real-time alert mechanisms that trigger autonomous vehicle rerouting in case of accidents, blockages, or congestion spikes.*Strengthened expertise in software development and data engineering, spanning simulation orchestration, system modeling, and cross-platform integration.Tech Stack:Python, Pandas, CARLA, SUMO, OSMnx, NetworkX, GeoPandas, Jupyter, Git, REST APIs, Matplotlib, Folium
