Julián Montejo is a PhD student at the Global Earthquake Model (GEM) Foundation and the Università Gabriele D’Annunzio at Chieti-Pescara, Italy. He is funded by the MSCA scholarship within the TREAD project. His doctoral research, Assessment of the impact of advanced seismic hazard modelling approaches in earthquake risk, investigates how different choices in hazard modelling affect the outcomes of Probabilistic Seismic Risk Analysis (PSRA). His work explores the influence of different aspects such as site models, site effects approaches, and epistemic uncertainty in hazard assessments on risk metrics. 
In his poster at EGU 2025, he presents a two-step methodology to design optimal site grids for PSRA. This approach controls both hazard and risk inputs to significantly reduce computational demand while maintaining accuracy in the resulting risk estimates.
