Joshua Panganiban

Hi, I'm Joshua — thank you for visiting my page!

I am a researcher and engineer working at the intersection of computational modeling, high-performance simulation, and real-world decision problems. My work focuses on developing numerical and simulation-based methods for analyzing complex physical and socio-economic systems, using empirical data to inform, calibrate, and validate models. My applications include disaster impact analysis, seismic resilience, and infrastructure decision-making.

In collaboration with the Computational Science and High-Performance Computing Laboratory at the Earthquake Research Institute, The University of Tokyo, I work on large-scale agent-based economic simulation. This research develops an HPC-enhanced agent-based simulator that uses firm-level and regional economic data to represent national-scale economies at 1:1 resolution. The framework is designed to estimate post-disaster economic impacts and support policy analysis for more effective recovery planning.

Currently, I am also a Research Engineer at Takeuchi Construction, Inc., where I contribute to the development of patented construction technologies for seismic base isolation and ground improvement. I primarily lead two research projects: a particle-based simulation framework for evaluating the vibration reduction performance of sandbag-based seismic isolation systems, and a neural network-enhanced analysis framework for foundation systems. These projects aim to support more cost-effective and resilient infrastructure solutions in earthquake-prone regions.

My broader research interest lies in micro-macro computational modeling: developing simulation frameworks that connect agent-, particle-, or component-level mechanisms with emergent system-level outcomes, particularly in infrastructure resilience, disaster impact analysis, and socio-economic systems.

In 2022, I worked as a Research Fellow with the Earthquakes and Megacities Initiative (EMI), where I contributed to the Climate and Disaster Risk Assessment for Quezon City, Philippines. My work focused on computational analysis of shelter needs and evacuation planning, supporting the development of tools for managing complex emergencies and strengthening disaster preparedness.

Before moving further into research, I worked as a Structural Engineer at the Manila office of JGC Holdings Corporation from 2019 to 2021, focusing on the analysis and design of oil and gas facilities and the development of structural design and automation tools. I am also a licensed Civil Engineer and Master Plumber in the Philippines, with prior freelance experience in residential design, building plans, and permit documentation.
