Research Interests
The researcher combines transportation science with empirical data collection and advanced optimization to address real-world urban mobility and engineering challenges. In urban transport, representative driving cycles were developed for high-congestion city routes in Guayaquil using direct real-world trip data from an M1 vehicle, processed with OBD tools and statistical analysis, and constructed with a weighting-based method. This work provides a robust basis for emission modeling, vehicle certification, and policy design in Latin American cities, illustrating how driving behavior, speeds, idle times, and acceleration patterns vary by route and affect emissions. In the domain of measurement and materials/industrial optimization, the work explores temperature-driven volumetric variations of gasoline and diesel in tanks, employing a thermographic-assisted mathematical model to visualize fuel dilatation, and identifies a notable 0.55% volume variation due to ambient temperature, with correlations showing temperature directly influences perceived volume though practical detection via thermography depends on tank volume and camera capabilities. A parallel study applies topological optimization to brake discs, balancing stresses, safety factors, and mass reduction, followed by computational fluid dynamics to assess heat dissipation and iteratively redesigning disc geometry; results show a 5 mm perforated design can reduce maximum temperature by 8 °C, underscoring the iterative nature of applying topology to obtain technically valid, performant components. Collectively, the research advances practical, data-driven methods for emissions-aware transport planning, fuel-volume assessment under environmental conditions, and optimized thermal management in mechanical components, highlighting methodological integration across sensors, optimization, and materials science to impact urban policy, automotive engineering, and manufacturing.
