Profile Summary

I am a university lecturer and researcher with interdisciplinary experience in scientific computing, optimization, control systems, GIS, spatial data analysis, and AI-based engineering applications. My academic background includes a PhD in Geography, with a strong focus on GIS and spatial analysis, followed by postdoctoral research and subsequent work in control science and engineering. This interdisciplinary background allows me to work comfortably across mathematical modeling, algorithm development, data analysis, simulation, and software implementation. My current research and development work focuses on complex engineering systems, including optimization and scheduling, networked control systems, aerospace transportation systems, UAV-related applications, multimodal transportation, and intelligent perception. I have also worked extensively on spatial-temporal modeling, route and network analysis, resource-constrained optimization, and simulation-based evaluation. My main technical skills include: - Scientific computing and numerical modeling using Python and MATLAB - Mathematical optimization, including MILP, scheduling, routing, and resource allocation - Control-system modeling, simulation, and algorithm development - GIS, spatial analysis, spatial networks, and geospatial data processing - Data analysis, visualization, statistical evaluation, and experiment design - Machine learning and computer vision prototyping - Research-code development, debugging, validation, and reproducibility - Technical writing, scientific reporting, and research methodology design I have authored and co-authored more than 20 academic publications and have extensive experience developing research prototypes, computational experiments, simulation frameworks, and reproducible analysis pipelines. For freelance and consulting projects, I am particularly interested in technically challenging tasks that require more than routine software development. I can help clients translate a complex scientific or engineering problem into a clear mathematical formulation, implement the solution in Python or MATLAB, validate the results, and deliver well-documented code, figures, and technical reports. I value clear communication, reproducibility, and technically defensible results, and I am comfortable working either independently or as part of a research or engineering team.
