Joshua started his career in research when he pursued a bachelor’s degree in civil engineering at the University of the Philippines Los Baños. In 2017, he initiated a collaboration with Prof. Madlangbayan (Civil Engineering Materials) and Prof. Tapia (Applied Spectroscopy), where he investigated the electrical signals exhibited by cement paste, an integral part of our current structural concrete technology. After passing the national licensure examination in 2018, he worked for a structural engineering firm that reviews and designs the structural integrity of high-rise buildings.

In 2019, he joined Stanford University as a Knight-Hennessy scholar studying two master’s degrees in civil engineering and public policy, where he worked with Prof. Noh (Stanford), Prof. Xu (Stony Brook), and Dr. Wald (USGS seismologist) to apply artificial intelligence (AI) to use NASA satellite imagery products to improve PAGER, the global earthquake loss estimation of the United States. He also worked with Prof. Baker (Stanford) to evaluate the probabilistic regional earthquake risk as a basis for equitable policies for the Greater Metro Manila Area in the Philippines.

In 2021, he served as a consulting assistant to Dr. Eng. Fouad Bendimerad, (a Stanford PhD Alumnus, 1985) and Stanford LBRE to analyze the financial and space losses of over 750 multi-million educational, real-estate, and residential buildings of Stanford University subjected to large earthquakes caused by the Hayward and San Andreas faults. He then continued working with Dr. Bendimerad as an Urban Resilience Fellow at EMI Philippines (an international scientific NGO), where he engaged on quantitative understanding of climate and disaster risks of Quezon City in the Philippines.

In 2022, he joined the UKRI EPSRC Centre for Doctoral Training in the Application of Artificial Intelligence to the study of Environmental Risks at the University of Cambridge to explore how AI can provide an improved understanding of the global resilience in response to intensifying effects of climate change and other natural hazards.
