Background & Vision

About Me

Bridging civil and transport infrastructure with modern computational data science.

I am a transport and infrastructure engineering researcher with interests in traffic engineering, transportation-related air pollution, intelligent transportation systems, spatial analysis, and data science.

My work combines transportation engineering with tools such as Python, R, GIS, Power BI, PTV Vissim, computer vision, and statistical analysis.

I am particularly interested in applying artificial intelligence, digital twins, traffic simulation, and environmental monitoring to improve sustainable urban mobility.

Transport Engineering

Traffic flow theory, intersection geometry, corridor optimization, and multimodal mobility solutions.

Data Science

Statistical regression, Monte Carlo uncertainty analysis, exploratory data analysis, and predictive modeling.

GIS

Spatial network mapping, catchment area accessibility, satellite imagery processing, and remote sensing.

Environmental Research

Traffic-related air pollution, ultrafine particle monitoring, tailpipe emission inventories, and urban health exposure.

Teaching

University lectures, technical workshops in Python, R, Power BI, Vissim, and mentoring next-generation engineers.

Research Collaboration

Cross-border partnerships with international research institutes, academic labs, ministries, and transport agencies.
